Introduction: Why Is the Electricity Market So Complex?<\/strong><\/p><p>The inherent complexity of the electricity market stems primarily from the imperative that electricity must be generated and consumed simultaneously (TE\u0130A\u015e). As electricity cannot be stored on a large scale, it necessitates a real-time, dynamic balance where supply and demand must match within milliseconds. The market mechanisms designed to achieve this delicate equilibrium result in a multifaceted structure, interwoven with numerous generation and consumption actors, transmission network constraints, and external factors (EPDK).<\/p><ul class=\"wp-block-list\"><li><strong>EP\u0130A\u015e&#8217;s Market Making and Regulatory Role:<\/strong> Energy Markets Operations Joint Stock Company (EP\u0130A\u015e) is a central and regulatory arm of the Turkish electricity market. Beyond merely operating as a market operator, EP\u0130A\u015e is responsible for managing critical markets such as the <strong>Day-Ahead Market (DAM)<\/strong>, <strong>Intra-Day Market (IDM)<\/strong>, and <strong>Balancing Power Market (BPM)<\/strong>. Its role extends to ensuring the transparency, reliability, and fair competitive conditions of these markets. EP\u0130A\u015e operates within the regulatory framework established by the Energy Market Regulatory Authority (EPDK), providing a level playing field for market participants and aiming to optimize the total cost of the system by ensuring the most efficient meeting of supply and demand (EP\u0130A\u015e).<\/li>\n\n<li><strong>Unpredictability of Prices and Its Impact on HPPs:<\/strong> Electricity prices constantly fluctuate under the influence of countless factors such as meteorological conditions, global fuel prices, unforeseen plant outages, transmission constraints, and even geopolitical developments. This unpredictability creates strategic challenges, particularly for <strong>hydroelectric power plants (HPPs) (<\/strong>HES\u0130AD). Unlike other power plants, HPPs have the ability to store their primary fuel, water. However, this advantage comes with the necessity of converting water into energy at the right time and at the right price. Hydrological conditions, such as drought periods or excessive rainfall, directly affect HPPs&#8217; generation potential, while market price uncertainties turn production planning and, consequently, revenue forecasting into a complex chess game (DS\u0130).<\/li>\n\n<li><strong>&#8220;Maximize Income, Not Production&#8221; Approach:<\/strong> In the traditional understanding of energy generation, the focus has often been on producing maximum electricity by utilizing the full technical capacity. However, in a competitive market environment, this approach doesn&#8217;t always yield the most profitable outcomes. Especially for resources with storage capabilities like HPPs, there has been a strategic shift: <strong>&#8220;Maximize income, not production.&#8221;<\/strong> This approach means using water as a resource when market prices are expected to be at their highest. For instance, instead of generating electricity late at night or during low demand periods, reserving water resources for times when high MCP values are expected during the day or week can significantly increase the revenue generated per unit of water. A deep understanding of MCP and balancing mechanisms is a crucial tool for HPP operators to implement this strategic vision. This ensures that power plants are not only technically efficient but also perform at the highest financial level (EP\u0130A\u015e).<\/li><\/ul><div class=\"wp-block-group is-nowrap is-layout-flex wp-container-core-group-is-layout-ad2f72ca wp-block-group-is-layout-flex\"><figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"462\" height=\"462\" src=\"https:\/\/renewasoft.com.tr\/wp-content\/uploads\/2025\/07\/image-31.png\" alt=\"\" class=\"wp-image-2489\" srcset=\"https:\/\/renewasoft.com.tr\/wp-content\/uploads\/2025\/07\/image-31.png 462w, https:\/\/renewasoft.com.tr\/wp-content\/uploads\/2025\/07\/image-31-300x300.png 300w, https:\/\/renewasoft.com.tr\/wp-content\/uploads\/2025\/07\/image-31-150x150.png 150w, https:\/\/renewasoft.com.tr\/wp-content\/uploads\/2025\/07\/image-31-262x262.png 262w, https:\/\/renewasoft.com.tr\/wp-content\/uploads\/2025\/07\/image-31-405x405.png 405w, https:\/\/renewasoft.com.tr\/wp-content\/uploads\/2025\/07\/image-31-400x400.png 400w, https:\/\/renewasoft.com.tr\/wp-content\/uploads\/2025\/07\/image-31-100x100.png 100w\" sizes=\"auto, (max-width: 462px) 100vw, 462px\" \/><\/figure>\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"466\" height=\"466\" src=\"https:\/\/renewasoft.com.tr\/wp-content\/uploads\/2025\/07\/image-32.png\" alt=\"\" class=\"wp-image-2490\" srcset=\"https:\/\/renewasoft.com.tr\/wp-content\/uploads\/2025\/07\/image-32.png 466w, https:\/\/renewasoft.com.tr\/wp-content\/uploads\/2025\/07\/image-32-300x300.png 300w, https:\/\/renewasoft.com.tr\/wp-content\/uploads\/2025\/07\/image-32-150x150.png 150w, https:\/\/renewasoft.com.tr\/wp-content\/uploads\/2025\/07\/image-32-262x262.png 262w, https:\/\/renewasoft.com.tr\/wp-content\/uploads\/2025\/07\/image-32-405x405.png 405w, https:\/\/renewasoft.com.tr\/wp-content\/uploads\/2025\/07\/image-32-400x400.png 400w, https:\/\/renewasoft.com.tr\/wp-content\/uploads\/2025\/07\/image-32-100x100.png 100w\" sizes=\"auto, (max-width: 466px) 100vw, 466px\" \/><\/figure><\/div><p><strong>2. Day-Ahead Market (DAM): What Is It?<\/strong><\/p><p>The Day-Ahead Market (DAM) is one of the fundamental pillars of the Turkish electricity market. As the name suggests, it is an organized market where electricity is bought and sold on an hourly basis for the delivery day ahead (EP\u0130A\u015e). The DAM allows market participants (generators, consumers, and supply companies) to submit their production and consumption plans in advance for the following day and to engage in energy trading accordingly. This process provides the system operator (TE\u0130A\u015e) with a preliminary projection of the next day\u2019s supply-demand balance, enabling the necessary adjustments for secure and stable system operation (TE\u0130A\u015e).<\/p><p><strong>2.1. Definition of DAM and EP\u0130A\u015e&#8217;s Role<\/strong><\/p><p>The DAM offers a transparent, competitive, and reliable platform for electricity trading.<\/p><ul class=\"wp-block-list\"><li><strong>Free Market Logic and Price Discovery:<\/strong> The DAM is fundamentally a platform where supply and demand freely interact. Electricity generators submit sell bids considering their production costs, marginal costs, and expected fuel prices. Electricity consumers or retail companies enter their buy bids into the system based on their consumption expectations. This mutual interaction enables <strong>price discovery<\/strong> in the market. In other words, market participants directly contribute to the price-setting process based on their own forecasts (EP\u0130A\u015e, EPDK).<\/li>\n\n<li><strong>1-Day-Ahead Planning and Risk Management:<\/strong> One of the most important functions of the DAM is to allow market participants to lock in their electricity generation and consumption for the next day. This enables both generators to plan their fuel supply and operations and consumers to forecast their costs and budgets. It serves as a proactive risk management tool, especially against sudden market fluctuations (EP\u0130A\u015e).<\/li>\n\n<li><strong>TE\u0130A\u015e&#8217;s Need to Maintain System Balance:<\/strong> Turkish Electricity Transmission Corporation (TE\u0130A\u015e) is the national transmission system operator responsible for the safe, stable, and uninterrupted operation of Turkey&#8217;s electricity transmission system. DAM results provide TE\u0130A\u015e with vital information about the expected supply-demand balance for the next day. With this data, TE\u0130A\u015e manages transmission constraints, determines necessary reserve capacities, and prepares for potential system imbalances. The DAM is an important leading indicator in TE\u0130A\u015e&#8217;s mission to ensure grid security (TE\u0130A\u015e).<\/li><\/ul><div class=\"wp-block-group is-nowrap is-layout-flex wp-container-core-group-is-layout-ad2f72ca wp-block-group-is-layout-flex\"><figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"474\" height=\"474\" src=\"https:\/\/renewasoft.com.tr\/wp-content\/uploads\/2025\/07\/image-33.png\" alt=\"\" class=\"wp-image-2491\" srcset=\"https:\/\/renewasoft.com.tr\/wp-content\/uploads\/2025\/07\/image-33.png 474w, https:\/\/renewasoft.com.tr\/wp-content\/uploads\/2025\/07\/image-33-300x300.png 300w, https:\/\/renewasoft.com.tr\/wp-content\/uploads\/2025\/07\/image-33-150x150.png 150w, https:\/\/renewasoft.com.tr\/wp-content\/uploads\/2025\/07\/image-33-262x262.png 262w, https:\/\/renewasoft.com.tr\/wp-content\/uploads\/2025\/07\/image-33-405x405.png 405w, https:\/\/renewasoft.com.tr\/wp-content\/uploads\/2025\/07\/image-33-400x400.png 400w, https:\/\/renewasoft.com.tr\/wp-content\/uploads\/2025\/07\/image-33-100x100.png 100w\" sizes=\"auto, (max-width: 474px) 100vw, 474px\" \/><\/figure>\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"453\" height=\"420\" src=\"https:\/\/renewasoft.com.tr\/wp-content\/uploads\/2025\/07\/image-34.png\" alt=\"\" class=\"wp-image-2492\" srcset=\"https:\/\/renewasoft.com.tr\/wp-content\/uploads\/2025\/07\/image-34.png 453w, https:\/\/renewasoft.com.tr\/wp-content\/uploads\/2025\/07\/image-34-300x278.png 300w, https:\/\/renewasoft.com.tr\/wp-content\/uploads\/2025\/07\/image-34-283x262.png 283w, https:\/\/renewasoft.com.tr\/wp-content\/uploads\/2025\/07\/image-34-437x405.png 437w, https:\/\/renewasoft.com.tr\/wp-content\/uploads\/2025\/07\/image-34-431x400.png 431w\" sizes=\"auto, (max-width: 453px) 100vw, 453px\" \/><\/figure><\/div><p><strong>2.2. Market Calendar and Timeline<\/strong><\/p><p>Operations in the DAM occur within a strict calendar and timeline. This ensures equal conditions and market transparency for all participants (EP\u0130A\u015e).<\/p><ul class=\"wp-block-list\"><li><strong>Hourly Bidding Times:<\/strong> Market participants submit their buy or sell bids for each hour of the next day (total 24 hours) to the EP\u0130A\u015e electronic platform until <strong>11:30 AM daily<\/strong> (may vary for public holidays and weekends). A separate price and quantity bid can be submitted for each hour (EP\u0130A\u015e).<\/li>\n\n<li><strong>Bid Revision Period and Closing:<\/strong> Participants can modify their bids as many times as they wish during the bidding period, based on their strategies or updated data. However, after the specified closing time of 11:30 AM, no further bid revisions are possible. This strict closing time is part of ensuring fairness and integrity in the market (EP\u0130A\u015e).<\/li>\n\n<li><strong>Publication of Results and Acceptance Processes:<\/strong> After the bid closing, EP\u0130A\u015e&#8217;s advanced algorithm comes into play. Generally, around <strong>12:30 PM<\/strong>, the DAM results, namely the hourly Market Clearing Prices (MCPs) and matched quantities, are published through EP\u0130A\u015e&#8217;s transparent platforms. Participants can view how their bids were matched through these results and complete their acceptance processes to finalize their operational plans for the next day (EP\u0130A\u015e).<\/li><\/ul><p><strong>2.3. Bid Types<\/strong><\/p><p>The DAM offers various bid types suitable for different operational constraints and commercial strategies of market participants (EP\u0130A\u015e).<\/p><ul class=\"wp-block-list\"><li><strong>Demand and Generation Bids:<\/strong> There are fundamentally two main bid types:<ul class=\"wp-block-list\"><li><strong>Generation Bids (Sell):<\/strong> Indicate how much electricity generation plants commit to sell at a certain price (EP\u0130A\u015e).<\/li>\n\n<li><strong>Demand Bids (Buy):<\/strong> Indicate how much electricity consuming entities or retail companies commit to buy at a certain price. Each bid includes a price and a quantity (in MWh) to be bought\/sold at that price (EP\u0130A\u015e).<\/li><\/ul><\/li>\n\n<li><strong>Minimum \u2013 Maximum Production Limits:<\/strong> Production facilities (thermal power plants, HPPs, etc.) are technically constrained to operate within a certain minimum (technical minimum generation) and maximum (installed capacity or instantaneous capacity) production range. These limits are specified in the bids and considered by the matching algorithm (TE\u0130A\u015e).<\/li>\n\n<li><strong>Flexibility: What is a Block Bid?<\/strong> Block bids are offers valid for a specific period consisting of consecutive hours (e.g., a 4-hour block). These bids operate on an &#8220;all or nothing&#8221; principle; meaning, either the entire bid is accepted, or it is entirely rejected (EP\u0130A\u015e). Block bids are strategically important, especially for HPPs with flexible generation capabilities or certain industrial facilities requiring continuous production. For instance, an HPP might submit a 4-hour block bid at a high price for the 12:00-16:00 period to capitalize on high price potential during midday. This is also a crucial strategy for pumped-hydro storage plants; block bids can be used to pump water during low-price hours and generate electricity during high-price hours (HES\u0130AD).<\/li><\/ul><div class=\"wp-block-image\"><figure class=\"aligncenter size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"377\" height=\"377\" src=\"https:\/\/renewasoft.com.tr\/wp-content\/uploads\/2025\/07\/image-35.png\" alt=\"\" class=\"wp-image-2493\" srcset=\"https:\/\/renewasoft.com.tr\/wp-content\/uploads\/2025\/07\/image-35.png 377w, https:\/\/renewasoft.com.tr\/wp-content\/uploads\/2025\/07\/image-35-300x300.png 300w, https:\/\/renewasoft.com.tr\/wp-content\/uploads\/2025\/07\/image-35-150x150.png 150w, https:\/\/renewasoft.com.tr\/wp-content\/uploads\/2025\/07\/image-35-262x262.png 262w, https:\/\/renewasoft.com.tr\/wp-content\/uploads\/2025\/07\/image-35-100x100.png 100w\" sizes=\"auto, (max-width: 377px) 100vw, 377px\" \/><\/figure><\/div><p><strong>2.4. Supply-Demand Balance and Price Matching<\/strong><br>In the DAM, price formation occurs at the point where all bids are matched\u2014that is, where supply meets demand. This process is typically guided by the \u201cmerit-order\u201d system (EP\u0130A\u015e).<\/p><p>\u2022 <strong>Merit-Order (Supply-Demand Ranking):<\/strong><br>EP\u0130A\u015e\u2019s matching algorithm ranks all sell offers from the lowest to highest price, forming a supply curve. Similarly, buy offers are ranked from highest to lowest price to create a demand curve. This ordering is designed to ensure that the system operates at the lowest possible cost (EP\u0130A\u015e).<\/p><p>\u2022 <strong>How Is the System Marginal Price (SMP) Determined?<\/strong><br>The SMP is the price formed at the intersection point of the supply and demand curves. This point reflects the cost of the last (most expensive) power plant needed to meet the total demand in the system. In other words, it represents the cost of supplying one additional unit of electricity for that hour. The SMP reflects the marginal equilibrium in the market (EP\u0130A\u015e).<\/p><p>\u2022 <strong>Determining the Clearing Offer:<\/strong><br>During the matching process, all sell offers equal to or below the SMP and all buy offers equal to or above the SMP are accepted. This ensures that all market participants transact at the same price\u2014the Market Clearing Price (MCP) (EP\u0130A\u015e, EPDK).<\/p><p><strong>2.5. <\/strong><strong>EP\u0130A\u015e Day-Ahead Market (DAM) Price Calculation Algorithm<\/strong><\/p><p>EP\u0130A\u015e utilizes advanced software to manage the bid matching and market clearing price (MCP) determination process in the Turkish day-ahead electricity market. This system meticulously analyzes bids submitted by market participants to determine the MCP for each hour, as well as the matched quantity and price for each bid (EP\u0130A\u015e).<\/p><p><strong>1. Bid Database and Structures:<\/strong> EP\u0130A\u015e collects all bids from market participants into a detailed database. There are three primary types of bids in the Turkish day-ahead electricity market: hourly, block, and flexible bids. Each bid includes at least one price-quantity pair and can be for buying or selling. If the quantity is negative, it indicates a sell; if positive, it indicates a buy. Quantities are expressed in lots, with one lot equivalent to 0.1 MWh.<\/p><ul class=\"wp-block-list\"><li><strong>Hourly Bids:<\/strong> Participants submit price-quantity breakpoints for each hour of the following day. For sell-side price breakpoints, quantities are specified as negative values. As price breakpoints increase, quantities are expected to decrease (i.e., buy quantities should decrease, and the absolute value of sell quantities should increase). Hourly bids form a piecewise linear function by allowing linear interpolation between breakpoints. The matched quantity is determined as the quantity corresponding to the MCP on this piecewise linear function (EP\u0130A\u015e).<ul class=\"wp-block-list\"><li><strong>Example:<\/strong> An hourly bid for a participant could be exemplified as follows:<\/li><\/ul><\/li><\/ul><figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><td>Price (\u20ba\/MWh)<\/td><td>10<\/td><td>50<\/td><td>100<\/td><td>150<\/td><td>200<\/td><td>250<\/td><\/tr><\/thead><tbody><tr><td>Quantity (lot)<\/td><td>200<\/td><td>150<\/td><td>100<\/td><td>50<\/td><td>-50<\/td><td>-100<\/td><\/tr><\/tbody><\/table><\/figure><ul class=\"wp-block-list\"><li><strong>Block Bids:<\/strong> Block bids are similar to consecutive hourly bids that cannot be fragmented across time. They have a single price-quantity pair for their entire effective duration and are submitted with the condition that the entire offered quantity must be accepted or rejected. A block bid is either fully accepted or fully rejected for the period it is active.<ul class=\"wp-block-list\"><li><strong>Linked Block Bids:<\/strong> If one block bid is linked to another, the linked bid is called a &#8220;child&#8221; bid, and the bid it is linked to is called a &#8220;parent&#8221; bid. If the parent bid is not accepted, the child block bid is also not accepted. A maximum of three block bids can be linked to each other, and they cannot form a circular dependency. Furthermore, linked block bids must be in the same direction (either all sell or all buy).<\/li>\n\n<li><strong>Example:<\/strong> An example of a linked block bid:<\/li><\/ul><\/li><\/ul><figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><td>Block Bid<\/td><td>Duration<\/td><td>Price (\u20ba\/MWh)<\/td><td>Quantity (lot)<\/td><td>Linked Block<\/td><\/tr><\/thead><tbody><tr><td>X<\/td><td>1-4<\/td><td>120<\/td><td>-200<\/td><td><\/td><\/tr><tr><td>Y<\/td><td>2-6<\/td><td>15<\/td><td>-80<\/td><td>X<\/td><\/tr><\/tbody><\/table><\/figure><p><em>In this example, for block bid Y to be accepted, block bid X must also be accepted.

Solution Method:<\/strong> The problem is solved through four main modules: pre-processing, heuristic algorithms, optimization, and post-processing algorithms (EP\u0130A\u015e).<\/p><ul class=\"wp-block-list\"><li><strong>Pre-processing:<\/strong> In this stage, data is read, hourly bids for each hour are aggregated into a single bid (aggregation), and variable elimination is performed to reduce the problem size without losing the optimal value (EP\u0130A\u015e).<\/li>\n\n<li><strong>Heuristic Algorithms:<\/strong> To provide the optimization module with an initial solution that has a high total surplus, two heuristic algorithms, such as Tabu Search and Genetic Algorithm, run in parallel. These algorithms focus on finding the block bid combination that yields the best total surplus, treating flexible bids as non-existent (or rejected). Once the most suitable block combination is found, flexible bids are added to this solution (EP\u0130A\u015e).<\/li>\n\n<li><strong>Optimization:<\/strong> The solution obtained from the heuristic algorithms is fed into a mathematical programming solver, aiming to find the best solution within a specified time limit. Both the constrained and unconstrained models (where constraints &#8216;e&#8217; and &#8216;g&#8217; of the model are absent) are solved by this solver. If the unconstrained model satisfies constraints &#8216;e&#8217; and &#8216;g&#8217;, this solution is taken as the final solution. Otherwise, the constrained model is solved, the solution of the unconstrained model is repaired to satisfy constraints &#8216;e&#8217; and &#8216;g&#8217;, and these two solutions are compared to declare the one yielding the highest total surplus. The problem is modeled as a Mixed Integer Quadratic Program (MIQP) (EP\u0130A\u015e).<\/li>\n\n<li><strong>Post-processing:<\/strong> This module includes the curtailment procedure applied in cases of supply or demand surplus, solution verification and repair algorithms, and reporting. Verification algorithms check the conformity of solutions produced by the heuristic and optimization modules with the constraints stated in Section 3.2. If a generated solution does not satisfy these constraints, a repair algorithm is used to make the solution feasible (EP\u0130A\u015e).<\/li><\/ul><p><strong>5. Demand or Supply Surplus Situations:<\/strong> In cases of energy deficit (demand surplus) or energy surplus (supply surplus), the supply and demand in the system cannot be balanced within the currently valid price limits in the market and while satisfying all the constraints mentioned in the preceding section. In such situations, to ensure supply-demand balance, hourly bids are curtailed, and the acceptance conditions for block and flexible bids may not be met (EP\u0130A\u015e).<\/p><ul class=\"wp-block-list\"><li><strong>Energy Surplus:<\/strong> In an energy surplus situation, the MCP for that hour is set at the minimum price (P_min). In this case, the total demand offered to the market at the minimum price (Demand(P_min)) is less than the total supply at this price (Supply(P_min)). The energy surplus in an hour is calculated as the difference between the supply and demand corresponding to the minimum price for that hour: Supply(P_min)\u2212Demand(P_min) (EP\u0130A\u015e).<\/li>\n\n<li><strong>Energy Deficit:<\/strong> In an energy deficit situation, the MCP for that hour is set at the maximum price (P_max). In this case, the total supply offered to the market at the maximum price (Supply(P_max)) is less than the total demand at this price (Demand(P_max)). The energy deficit in an hour is calculated as the difference between the demand and supply corresponding to the maximum price for that hour: Demand(P_max)\u2212Supply(P_max) (EP\u0130A\u015e).<\/li><\/ul><figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"899\" height=\"617\" src=\"https:\/\/renewasoft.com.tr\/wp-content\/uploads\/2025\/07\/image-60.png\" alt=\"\" class=\"wp-image-2520\" srcset=\"https:\/\/renewasoft.com.tr\/wp-content\/uploads\/2025\/07\/image-60.png 899w, https:\/\/renewasoft.com.tr\/wp-content\/uploads\/2025\/07\/image-60-300x206.png 300w, https:\/\/renewasoft.com.tr\/wp-content\/uploads\/2025\/07\/image-60-768x527.png 768w, https:\/\/renewasoft.com.tr\/wp-content\/uploads\/2025\/07\/image-60-350x240.png 350w, https:\/\/renewasoft.com.tr\/wp-content\/uploads\/2025\/07\/image-60-540x371.png 540w, https:\/\/renewasoft.com.tr\/wp-content\/uploads\/2025\/07\/image-60-729x500.png 729w, https:\/\/renewasoft.com.tr\/wp-content\/uploads\/2025\/07\/image-60-583x400.png 583w, https:\/\/renewasoft.com.tr\/wp-content\/uploads\/2025\/07\/image-60-600x412.png 600w\" sizes=\"auto, (max-width: 899px) 100vw, 899px\" \/><\/figure><p><strong><u>Now, let&#8217;s illustrate these explanations with an example:<\/u><\/strong><\/p><p><em>(This example has been generated using artificial intelligence.)<\/em><\/p><p>In this example, we will use hypothetical data for a single hourly period (e.g., 1:00 PM).

The Importance of the DAM for HPPs<\/strong><br>For hydroelectric power plant (HPP) operators, the DAM is more than just a pricing bulletin\u2014it is a strategic decision-making platform (HES\u0130AD).<\/p><p>\u2022 <strong>Planning = Profit Estimation and Optimal Resource Use:<\/strong><br>Thanks to their storage capabilities, HPPs use water as a \u201cstorable fuel.\u201d DAM prices provide strong signals as to when this \u201cfuel\u201d becomes most valuable. By analyzing DAM price curves, HPP operators can plan next-day production, optimize water allocation, and maximize potential profit. Proper planning ensures that water is converted into energy at the most profitable moment (DS\u0130).<\/p><p>\u2022 <strong>Reducing Imbalance Risk and Avoiding Penalty Mechanisms:<\/strong><br>In electricity markets, any deviation between declared and actual generation or consumption is considered an \u201cimbalance.\u201d These imbalances may result in additional costs (penalties) through the Balancing Power Market (BPM) mechanisms (EP\u0130A\u015e). Submitting accurate and realistic DAM bids helps HPPs avoid unnecessary exposure to balancing mechanisms and thus minimizes potential imbalance costs (TE\u0130A\u015e).<\/p><p>\u2022 <strong>Water Management and the \u201cPrice-Timing\u201d Relationship:<\/strong><br>An HPP\u2019s most valuable asset is water. The DAM offers HPP operators the opportunity to integrate water management with market prices. Generating electricity during high PTF hours (peak hours) and storing water during low PTF hours (off-peak hours) can significantly increase a plant\u2019s revenue. This \u201cprice-timing\u201d relationship is especially crucial for reservoir-based HPPs, requiring long-term strategic management of water reserves (HES\u0130AD). Simply put, the key is to capture the moment when water yields the highest return per kWh.<\/p><figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"474\" height=\"474\" src=\"https:\/\/renewasoft.com.tr\/wp-content\/uploads\/2025\/07\/image-1.jpg\" alt=\"\" class=\"wp-image-2511\" srcset=\"https:\/\/renewasoft.com.tr\/wp-content\/uploads\/2025\/07\/image-1.jpg 474w, https:\/\/renewasoft.com.tr\/wp-content\/uploads\/2025\/07\/image-1-300x300.jpg 300w, https:\/\/renewasoft.com.tr\/wp-content\/uploads\/2025\/07\/image-1-150x150.jpg 150w, https:\/\/renewasoft.com.tr\/wp-content\/uploads\/2025\/07\/image-1-262x262.jpg 262w, https:\/\/renewasoft.com.tr\/wp-content\/uploads\/2025\/07\/image-1-405x405.jpg 405w, https:\/\/renewasoft.com.tr\/wp-content\/uploads\/2025\/07\/image-1-400x400.jpg 400w, https:\/\/renewasoft.com.tr\/wp-content\/uploads\/2025\/07\/image-1-100x100.jpg 100w\" sizes=\"auto, (max-width: 474px) 100vw, 474px\" \/><\/figure><p><strong>2.7.

A deep understanding of these factors is essential for developing MCP forecasting models and managing risks.<\/p><ul class=\"wp-block-list\"><li><strong>Meteorological Conditions (Drought, Temperature, Wind, Solar):<\/strong> Weather conditions are one of the most decisive natural factors affecting the MCP.<ul class=\"wp-block-list\"><li><strong>Temperature:<\/strong> Rising temperatures in summer boost air conditioning use, causing electricity demand to peak, while cold temperatures in winter increase heating demand. These surges in demand push the MCP upwards (HES\u0130AD).<\/li>\n\n<li><strong>Drought:<\/strong> A decrease in water, the primary fuel for HPPs, restricts hydroelectric generation. This situation forces more expensive thermal power plants into operation in the market, driving the MCP higher (HES\u0130AD).<\/li>\n\n<li><strong>Wind and Solar:<\/strong> Wind speed and solar irradiance directly affect the output of wind and solar power plants (WPPs, SPPs). When the generation from these renewable sources increases (during windy\/sunny weather), the supply of cheap electricity to the market rises, and the MCP tends to fall. Conversely, the MCP can increase (HES\u0130AD).<\/li><\/ul><\/li>\n\n<li><strong>Fuel Prices (Natural Gas, Coal, Oil):<\/strong> Natural gas and coal have a significant share in Turkey&#8217;s electricity generation mix. Fluctuations in the global market prices of these fuels, exchange rate movements, and national taxation policies directly impact the MCP. Especially natural gas power plants, due to their flexibility, often act as the marginal price-setting resources. A single unit increase in natural gas prices can raise the bid prices of natural gas power plants, consequently increasing the MCP (EP\u0130A\u015e).<\/li>\n\n<li><strong>Generation Type and Cost Structure (Baseload, Flexible Resources):<\/strong><ul class=\"wp-block-list\"><li><strong>Baseload Power Plants:<\/strong> Facilities like nuclear and some coal-fired power plants, typically with low marginal costs (but high fixed costs), generally operate at a constant output for most of the day, covering the market&#8217;s baseload demand.<\/li>\n\n<li><strong>Mid-Load and Peaker Plants:<\/strong> More agile power plants like combined cycle gas turbines (CCGTs), which can start up and shut down faster but have higher marginal costs, come into operation during &#8220;peak&#8221; hours when demand increases or baseload plants are insufficient, thereby determining the MCP (EPDK, EP\u0130A\u015e).<\/li><\/ul><\/li>\n\n<li><strong>Technical Faults, Maintenance Plans, and Transmission Constraints:<\/strong> Unexpected outages or planned maintenance work at large generation plants instantly reduce market supply and can cause the MCP to rise. Additionally, capacity constraints in electricity transmission lines (transmission congestion) can also lead to regional price differentiations or increases in the MCP in certain areas (TE\u0130A\u015e, EP\u0130A\u015e).<\/li><\/ul><div class=\"wp-block-group is-nowrap is-layout-flex wp-container-core-group-is-layout-ad2f72ca wp-block-group-is-layout-flex\"><figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"396\" height=\"396\" src=\"https:\/\/renewasoft.com.tr\/wp-content\/uploads\/2025\/07\/image-61.png\" alt=\"\" class=\"wp-image-2521\" srcset=\"https:\/\/renewasoft.com.tr\/wp-content\/uploads\/2025\/07\/image-61.png 396w, https:\/\/renewasoft.com.tr\/wp-content\/uploads\/2025\/07\/image-61-300x300.png 300w, https:\/\/renewasoft.com.tr\/wp-content\/uploads\/2025\/07\/image-61-150x150.png 150w, https:\/\/renewasoft.com.tr\/wp-content\/uploads\/2025\/07\/image-61-262x262.png 262w, https:\/\/renewasoft.com.tr\/wp-content\/uploads\/2025\/07\/image-61-100x100.png 100w\" sizes=\"auto, (max-width: 396px) 100vw, 396px\" \/><\/figure>\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"446\" height=\"400\" src=\"https:\/\/renewasoft.com.tr\/wp-content\/uploads\/2025\/07\/image-62.png\" alt=\"\" class=\"wp-image-2522\" srcset=\"https:\/\/renewasoft.com.tr\/wp-content\/uploads\/2025\/07\/image-62.png 446w, https:\/\/renewasoft.com.tr\/wp-content\/uploads\/2025\/07\/image-62-300x269.png 300w, https:\/\/renewasoft.com.tr\/wp-content\/uploads\/2025\/07\/image-62-292x262.png 292w\" sizes=\"auto, (max-width: 446px) 100vw, 446px\" \/><\/figure><\/div><p><strong>3.3. Formulating HPP Strategies Based on the Market Clearing Price (MCP)<\/strong><br>For hydropower plants (HPPs), the PTF is more than just an indicator; it is a fundamental signal shaping both operational and financial strategies.<\/p><p>\u2022 <strong>Matching Forecasts with Timing and Arbitrage Opportunities:<\/strong><br>HPP operators attempt to predict future PTF trends using advanced forecasting models and market analyses. These forecasts are used to plan the optimal utilization of water resources. The core strategy involves storing water when it is \u201ccheap\u201d (i.e., when the opportunity cost is low) and converting it to electricity for sale when prices are \u201cexpensive\u201d (i.e., when high PTF values are expected). This approach, known as price arbitrage, is the most effective strategy enabled by the natural storage capability of HPPs (HES\u0130AD).<\/p><p>\u2022 <strong>Increasing Generation During High PTF Hours:<\/strong><br>Typically, on business days, electricity demand peaks during morning and evening hours, causing the PTF to rise. As long as ramping capabilities and reservoir levels permit, HPPs can maximize their generation during these high-price hours to optimize revenue. This strategy is the main focus of daily or weekly water management for reservoir-based hydropower plants (EP\u0130A\u015e).<\/p><p>\u2022 <strong>Efficiency Analysis and Risk Management Through Price-Water Scenarios:<\/strong><br>Using advanced software and analytical models, it is possible to perform detailed efficiency analyses under various PTF forecast scenarios (optimistic, realistic, pessimistic), different hydrological conditions (drought, normal, wet), and operational constraints of the HPP (turbine efficiency, water level limits). These analyses help pre-assess potential revenues, costs, and risks. Furthermore, risk mitigation strategies against price fluctuations in the DAM can be developed by using bilateral contracts or financial hedging instruments. This is crucial for ensuring the financial stability of HPP operations (DS\u0130).<\/p><div class=\"wp-block-group is-nowrap is-layout-flex wp-container-core-group-is-layout-ad2f72ca wp-block-group-is-layout-flex\"><figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"436\" height=\"436\" src=\"https:\/\/renewasoft.com.tr\/wp-content\/uploads\/2025\/07\/image-63.png\" alt=\"\" class=\"wp-image-2523\" srcset=\"https:\/\/renewasoft.com.tr\/wp-content\/uploads\/2025\/07\/image-63.png 436w, https:\/\/renewasoft.com.tr\/wp-content\/uploads\/2025\/07\/image-63-300x300.png 300w, https:\/\/renewasoft.com.tr\/wp-content\/uploads\/2025\/07\/image-63-150x150.png 150w, https:\/\/renewasoft.com.tr\/wp-content\/uploads\/2025\/07\/image-63-262x262.png 262w, https:\/\/renewasoft.com.tr\/wp-content\/uploads\/2025\/07\/image-63-405x405.png 405w, https:\/\/renewasoft.com.tr\/wp-content\/uploads\/2025\/07\/image-63-400x400.png 400w, https:\/\/renewasoft.com.tr\/wp-content\/uploads\/2025\/07\/image-63-100x100.png 100w\" sizes=\"auto, (max-width: 436px) 100vw, 436px\" \/><\/figure>\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"436\" height=\"436\" src=\"https:\/\/renewasoft.com.tr\/wp-content\/uploads\/2025\/07\/image-64.png\" alt=\"\" class=\"wp-image-2524\" srcset=\"https:\/\/renewasoft.com.tr\/wp-content\/uploads\/2025\/07\/image-64.png 436w, https:\/\/renewasoft.com.tr\/wp-content\/uploads\/2025\/07\/image-64-300x300.png 300w, https:\/\/renewasoft.com.tr\/wp-content\/uploads\/2025\/07\/image-64-150x150.png 150w, https:\/\/renewasoft.com.tr\/wp-content\/uploads\/2025\/07\/image-64-262x262.png 262w, https:\/\/renewasoft.com.tr\/wp-content\/uploads\/2025\/07\/image-64-405x405.png 405w, https:\/\/renewasoft.com.tr\/wp-content\/uploads\/2025\/07\/image-64-400x400.png 400w, https:\/\/renewasoft.com.tr\/wp-content\/uploads\/2025\/07\/image-64-100x100.png 100w\" sizes=\"auto, (max-width: 436px) 100vw, 436px\" \/><\/figure><\/div><p><strong>RENEWASOFT&#8217;S SOLUTION \u2013 DAM + MCP Supported Decision Module<\/strong><\/p><p>The complexity of the Turkish electricity market and the continuous variability of the MCP can make it challenging for HPP operators and energy trading companies to make the right decisions at the right time.
