Understanding Capture Prices in Renewable Energy Markets

As the global transition to renewable energy accelerates, energy producers face increasing complexity in market operations, pricing mechanisms, and revenue management. Among the key financial metrics influencing profitability in renewable energy markets is capture price—a critical indicator that determines how much revenue a producer earns per megawatt-hour (MWh) of electricity sold.

Capture prices are especially important for variable renewable energy sources (VRES) like wind and solar, which depend on natural conditions rather than controlled fuel inputs. Unlike traditional power plants that can generate electricity on demand, renewable generators must operate within the availability of their energy source—whether it's the sun shining or the wind blowing. As a result, their revenue is subject to fluctuations in market prices, demand levels, and grid constraints.

Capture Price Definition

Capture prices represent the average price per megawatt-hour (MWh) received by a renewable energy producer for electricity sold in the market. Unlike fixed electricity tariffs or Power Purchase Agreements (PPAs), capture prices fluctuate based on real-time market conditions, meaning that renewable energy generators may earn different amounts for each unit of electricity they produce.

Capture Prices in the Renewable Energy Industry

In the context of renewable energy markets, capture price is defined as the weighted average market price received by a generator for the electricity it produces and sells over a given period. In a simplified version, the formula for calculating capture price typically follows this structure:

This calculation highlights that the capture price is not a static figure but varies based on the timing of generation, market prices at different hours, and the interaction of supply and demand dynamics.

For example, a wind farm that generates electricity predominantly during off-peak hours may receive a lower capture price compared to a solar farm whose production aligns with peak midday demand when prices are higher. This discrepancy can significantly impact revenue and long-term financial planning.

Why Should You Track Capture Prices?

Tracking capture prices is essential for asset managers overseeing renewable energy portfolios. Unlike fixed tariffs, capture prices fluctuate based on supply and demand, making them a critical factor in financial planning and market strategy. Understanding capture prices provides key insights that help maximise profitability and mitigate financial risks. Below are the main reasons why you should continuously monitor and analyse capture prices.

1. Optimising Bidding Strategies in Energy Markets

In competitive electricity markets, renewable energy producers must strategically position their bids to maximise revenues. Capture prices provide real-time insight into when and how much revenue assets are generating per MWh, allowing asset managers to refine their bidding strategies.

• Day-Ahead and Intraday Market Participation: By tracking capture prices, managers can anticipate periods of high or low market value, allowing them to optimise when energy is sold.
• Demand Forecasting Adjustments: If capture prices indicate significant fluctuations, producers can adjust generation schedules (where flexibility allows) to maximise revenues during peak pricing periods.
• Reducing Exposure to Negative Prices: By analysing trends in capture prices, asset managers can avoid bidding at times when electricity prices turn negative, helping to minimise losses.

2. Assessing Asset Performance and Profitability Trends

Capture prices act as a direct measure of the revenue potential of renewable assets. By tracking them over time, asset managers can evaluate how well their wind, solar, or hydro assets are performing relative to market conditions.

• Comparing Asset Performance Across Locations: Different regions may have varying capture prices due to grid congestion, curtailment risks, and market supply-demand dynamics. Monitoring these variations helps assess where assets are most profitable.
• Technology-Specific Price Trends: Solar and wind assets often experience different capture price trends based on generation patterns. Wind farms, for instance, may face lower capture prices due to overgeneration at night, while solar farms often benefit from higher daytime market prices.
• Evaluating the Impact of Curtailment: If an asset frequently experiences curtailment, this will directly impact its realised capture price. By monitoring capture price trends, asset managers can quantify financial losses due to curtailment.

3. Informing Investment Decisions and PPA Negotiations

Long-term investment strategies and Power Purchase Agreements (PPAs) require a deep understanding of how capture prices evolve.

• Choosing the Right Market Structure: For asset managers negotiating new PPAs, historical and projected capture prices help determine whether fixed-price contracts, merchant models, or hybrid structures will be most profitable.
• Assessing Long-Term Revenue Potential: By tracking capture price patterns over time, investors can make data-driven decisions about asset expansions, repowering projects, or divestments.
• Technology & Portfolio Diversification: Monitoring capture prices enables asset managers to decide whether to diversify their portfolio with storage solutions, hybrid renewable plants, or alternative market strategies.

4. Evaluating Market Risks and Adjusting Portfolios Accordingly

Capture prices are a key indicator of market risks that can affect the profitability of renewable energy assets.

• Identifying Market Saturation Risks: If capture prices for a particular technology consistently trend downward, it may indicate oversupply in the market.
• Adjusting Portfolio Strategies: Asset managers can use capture price data to optimise their portfolio by shifting investments into higher-value markets or considering hybrid solutions like battery storage to enhance revenue potential.
• Regulatory & Policy Impacts: Changes in subsidies, grid access rules, or market regulations can influence capture prices. Tracking these shifts allows asset managers to anticipate potential risks and adapt accordingly.

5. Regulatory & Policy Considerations

• Many governments and energy regulators consider capture prices when designing support mechanisms such as Contracts for Difference (CfDs) or capacity markets.
• Understanding capture prices allows policymakers to adjust market structures and ensure fair competition between different energy sources.

The Challenges of Managing Capture Prices

For renewable energy producers, maximising revenue requires a deep understanding of capture price trends and influencing factors. However, this is easier said than done. Key challenges include:

• Market Volatility: Electricity prices can fluctuate due to demand shifts, regulatory changes, or fuel price variations.
• Grid Congestion & Curtailment: Overloaded transmission networks can force renewable producers to reduce their output, affecting revenue.
• Forecasting Uncertainty: Renewable energy production is highly dependent on weather conditions, making it difficult to predict exact generation and corresponding market prices.
• Competition & Market Saturation: As more renewable energy assets enter the market, surplus generation during peak production periods can drive prices lower.
• Technology Type: Solar and wind have different capture price profiles due to their unique generation patterns.
• Geographic Location: Regions with strong renewable penetration may experience lower capture prices due to supply saturation, while areas with limited renewable capacity may offer better price signals.
