The transition to renewable energy increasingly depends on hybrid power plants that combine multiple technologies behind a single grid connection. While these projects improve grid flexibility and revenue potential, they are also much more difficult to design. Engineers must balance variable wind and solar generation with battery storage while optimizing plant layouts to reduce losses such as turbine wake effects and solar shading.
The National Renewable Energy Laboratory (NREL) developed the Hybrid Optimization and Performance Platform (HOPP) to solve these challenges. The platform provides an advanced open-source framework for simulating, optimizing, and evaluating hybrid renewable energy systems from both technical and financial perspectives.
What Is Hybrid Optimization and Performance Platform (HOPP)?
Hybrid Optimization and Performance Platform (HOPP) is an open-source renewable energy modeling and optimization tool created by NREL for analyzing large-scale hybrid power plants.
The platform combines wind, solar PV, battery storage, and other renewable technologies into one simulation environment where users can evaluate plant performance, dispatch strategies, and project economics using high-resolution resource and financial data.
