The Importance of Retail Electricity Rate Forecasting

The Importance of Retail Electricity Rate Forecasting

As opportunities for distributed energy generation projects continue to grow rapidly in energy markets across the US, so too does the importance of retail electricity rate forecasting. Rising retail rates boost revenue potential for distributed generation developers and operators, especially in high-demand, capacity-constrained markets.

Accurate retail rate forecasts allow distributed energy developers to quickly and confidently advance projects and portfolios related to community solar, storage, virtual power plants (VPPs), and behind-the-meter installations.  When combined with a wholesale price forecast that accounts for the changing dynamics of modern power markets, retail rate forecasts also allow developers to create pricing strategies that maximize revenue, minimize risk, and satisfy consumers.

Why Should Distributed Energy Developers Care About Retail Rates?

For most community solar and community storage projects, retail electricity rates are fundamental to generating stable revenue flows, since revenues are tied to bill credits which are based on utility retail rates.  

Once a community solar project is connected to the grid, participants in that project receive bill credits from their utility for their share of the project’s energy. Developers then generate revenue by charging participants – who are also utility ratepayers – a fee tied to the bill credit’s value, which is usually a fixed percentage of the total credit.  In most markets the bill credits are tied to retail electricity rates, which are more stable, produce higher returns, and are less volatile than merchant rates.

Beyond community solar, retail rates are fundamental to the value of net metered projects, load management/peak shaving applications for behind-the-meter energy storage, and other use cases.  

What Parts of Retail Electricity Charges Can Developers Recover Through Community Solar Bill Credits?

As shown in Figure 1, developers can fully recoup supply charges, which are included in the bill credit. And while  supply charges follow wholesale pricing trends, they are more predictable for distributed generation (as opposed to merchant) projects since rates change monthly or seasonally rather than hourly​. Often, developers can recover transmission costs and, depending on the market, can sometimes recover distribution costs.

Transmission and distribution (T&D) charges will increase over time as upgrades to grid infrastructure are needed for reliability​. T&D charges also help hedge against fluctuations in the supply rate and boost overall revenues for developers relative to wholesale market​s. Other incentives beyond bill credits may be available for energy project developers, depending on the program​ or market.

What is Retail Electricity Rate Forecasting?

At the most basic level, retail electricity rate forecasts provide anticipated outcomes for the way that future retail energy prices will move over time in a specific state or power market. The right retail rate forecasts allow distributed energy project developers and investors to optimize strategies and operations in order to maximize revenue potential, minimize risk, and satisfy consumers.

What Should a High-Quality Retail Rate Forecast Include?

A high-quality retail rate forecast should be linked to wholesale market dynamics, policy shifts, and risk factors, and should thus yield projections that more accurately capture the timing and scale of future rate changes.

Robust forecasts should offer in-depth insights into key retail electricity rate components – including supply, transmission, and distribution – tailored for specific states and/or energy markets. Additionally, a good forecast should be steeped in market fundamentals and utility- and rate-class-specific behaviors, and should combine a historical analysis of retail rate behavior with an in-depth analysis of wholesale costs including energy prices, capacity prices, and renewable energy credit (REC) curves.

What Types of Projects Do Retail Rate Forecasts Support?

Retail electricity rate forecasts are crucial components for a range of distributed energy generation projects, including community solar and storage, behind-the-meter projects and portfolio valuations, post-PPA revenue assessments, virtual power plants (VPPs), and aggregated distributed assets.
