The energy landscape is transforming to be able to serve drastically increasing baseload demands. Natural gas is continuing to play a critical role in supporting this evolution ensuring grid reliability and flexibility. Accurate valuation and operational cost forecasting are essential for natural gas developers to ensure the feasibility and profitability of new generation assets.
This blog examines the methodology for valuing natural gas-fired generation, featuring a case study on a specific project in ERCOT South that was selected for the Texas Energy Investment fund, and leveraged Acelerex’s REX Grid Analytics platform.
The Role of Natural Gas in the Energy Market
Natural gas-fired generation plays a critical role in the modern energy landscape, acting as a reliable baseload generation technology. By offering a dispatchable and flexible solution, natural gas generators can complement the variability of renewable resources like solar and wind, ensuring grid stability and meeting peak demand periods. Additionally, advancements in natural gas technology have improved efficiency, reduced emissions, and enabled better integration with emerging energy storage systems.
For developers, the economic viability of natural gas projects hinge on a detailed evaluation of both revenue potential and operational risks. A thorough understanding of market dynamics, regulatory frameworks, and cost structures is essential to make informed investment decisions and maximize project returns.
Key considerations in natural gas generation valuation include:
• Energy Price Forecasting: Estimating revenue opportunities based on wholesale market prices. This includes forecasting long-term price trends, peak pricing periods, and locational pricing differences to assess potential profitability. • Operational Costs: Analyzing fixed and variable operational costs, such as heat rates, auxiliary loads, and start-up expenses. Efficient cost management ensures competitive performance in wholesale energy markets.
• Market Risks: Addressing regulatory changes, sub-market participation, and external economic trends. Projects must be resilient to shifting grid requirements, energy policies, and market conditions to safeguard profitability.
• Technological Integration: Evaluating compatibility with grid modernization initiatives, such as advanced metering, demand response programs, and integration with renewable resources or battery storage.
• Revenue Stack Potential: Exploring additional revenue opportunities beyond energy generation, including ancillary services, reliability-based payments, and participation in demand response markets.
As the energy market continues to evolve, natural gas-fired generation remains a cornerstone for balancing reliability, flexibility, and efficiency. Developers must stay proactive in adapting their strategies to align with technological advancements and regulatory changes while pursuing opportunities for innovation and growth.

Solution Implementation:
Price Forecast
Acelerex employs the Integrated Hourly Resource (IHR) methodology to forecast energy prices from 2024 to 2048, providing insights into the long-term market landscape.
Key inputs include:
• Historical price data
• Henry Hub natural gas price forecasts from the U.S. Energy Information Administration (EIA).
• A maximum energy price cap of $5,000/MWh, adhering to ERCOT’s market dynamics.
The model predicts weekly average prices, offering the developer a detailed understanding of revenue opportunities.
Model Parameters for Valuation
• Node ID and Generation Capacity: Specifies the location and size of the generators.
• Variable Operation and Maintenance Costs (VOM): Includes maintenance costs per MWh.
• Heat Rate and Fuel Consumption: Reflects efficiency and fuel usage at full and no-load conditions.
• Market Transaction Costs: Accounts for participation costs in ERCOT’s sub-markets.
• Risk Analysis: Highlights potential impacts of market rule changes, economic trends, and unforeseen costs.
Valuation Methodology Employ a comprehensive approach to valuation, integrating data-driven insights and advanced algorithms:
- Data Services: Access to nodal market data, utility rates, weather data, and regulatory frameworks.
- Forecast Algorithms: Econometric and AI models for energy, ancillary services, and fuel price forecasting.
- NPV and DCF Analysis: Detailed financial modeling, including capital and operational expenses, to calculate Net Present Value (NPV) and Internal Rate of Return (IRR).
- SSE Tool: Simulates dispatch scenarios, sales, and profitability under hourly and sub-hourly market rules.
Risk Considerations While the forecasted revenue and valuation are promising, several risk factors could influence project outcomes: • Participation in ERCOT’s multiple sub-markets introduces variability. • Changes in ERCOT’s market rules and grid signals could materially impact valuation. • Assumptions regarding equipment and EPC costs may vary due to unforeseen circumstances.
