Curtailment Planning: Tools for Solar Professionals

Solar curtailment is a growing challenge for developers and asset owners. When solar energy production exceeds demand, grid operators cut output, leading to revenue loss. For instance, a 5% annual curtailment on a utility-scale project could cost hundreds of thousands of dollars over its lifetime.

To navigate this, solar professionals need tools that predict curtailment risks, analyze grid congestion, and optimize project design. The article reviews four platforms offering these capabilities:

• EasySolar: Simplifies design with AI-driven layouts, financial analysis, and collaboration tools. Great for smaller projects with its affordable plans.
• Yes Energy Suite: Delivers long-term market forecasts, grid insights, and simulation tools tailored for U.S. electricity markets.
• Enverus Power & Renewables: Combines real-time market data with advanced modeling to assess financial risks and regulatory compliance.
• windPRO by EMD International: Focuses on grid capacity and transmission bottlenecks, offering seasonal and scenario-based analysis.

Each tool has strengths suited to different project sizes and needs. The right choice depends on your project’s scale, budget, and technical requirements.

Curtailment Insights

A major hurdle in solar development is managing curtailment in grids with high renewable energy penetration. GridSite™ addresses this by delivering clear, long-term nodal Locational Marginal Price (LMP) forecasts. These hourly price projections extend through 2050, giving developers a solid foundation to evaluate revenue risks.

The tool also sheds light on the "duck curve" phenomenon – when midday solar surges coincide with low demand, leading to curtailment. This understanding helps developers anticipate and plan for the economic impacts of curtailment on their projects.

Integrated Data for Better Planning

Beyond forecasting, Yes Energy Suite excels at integrating critical data. By combining ISO interconnection data with other key sources, the platform tracks upcoming transmission and load center projects. This visibility is essential for predicting future curtailment risks, especially in regions where planned renewable projects might overwhelm transmission capacity.

Additionally, the platform allows users to compare the performance and revenue of similar projects. By analyzing existing projects’ operations, revenue streams, and offtake agreements, developers can learn how others have navigated curtailment challenges and structured agreements to reduce financial exposure.

Advanced Simulation Tools

GridSite™ also offers robust simulation capabilities. It uses historical data on pricing, load, generation, and congestion to model scenarios involving transmission constraints and curtailment events.

These simulations provide a clearer picture of how grid congestion and transmission bottlenecks have evolved. Developers can use these insights to make informed decisions about site selection and power offtake strategies, minimizing the risk of curtailment.

Tailored for the US Market

Designed specifically for US electricity markets, Yes Energy Suite aligns with domestic market standards. The platform keeps solar professionals up-to-date on interconnection queues and transmission planning processes, ensuring they are aware of infrastructure developments that could influence curtailment risks.

Its LMP forecasting is tailored to the unique structures of US electricity markets, helping developers understand how curtailment impacts vary across regional transmission organizations and utility territories.
