1. California Public Utilities Commission allows renewable energy systems to interconnect to the electric grid using Limited Generation Profiles (LGP)
2. Utilities must provide hosting capacity data for each node on their distribution system, allowing clean energy developers to design LGPs to avoid costly grid infrastructure upgrades
3. CPUC limits instances of permanent curtailment of power output from renewable energy systems connected using LGPs, with utilities responsible for upgrades to avoid such situations
The California Public Utilities Commission has approved the use of Limited Generation Profiles (LGPs) for renewable energy systems to connect to the electric grid, based on public grid data. This approach aims to reduce the need for infrastructure upgrades and support higher levels of renewables on the grid. Developers can use Integration Capacity Analysis to design an LGP and ensure projects stay within hosting capacity limits.
The Commission ruled that certified power control systems will be the primary option for managing LGPs, effective nine months after UL updates its certification standard. LGPs will have a 24-value configuration allowing export levels to vary up to 24 times per year, with three different formats available.
In cases where utilities need to curtail power output of a renewable energy system due to changing grid conditions, long-term or permanent curtailment will be limited to instances of sustained load reduction. Utilities are responsible for upgrades to avoid such situations, with the possibility of applying for a tariff deviation for permission to curtail if needed upgrades are deemed unreasonable.
Overall, the Commission’s decision aims to streamline the interconnection process for renewable energy systems in California, ensuring grid stability while supporting the growth of clean energy.
