California Interconnection Rules Update

In mid-March, the California Public Utilities Commission approved new interconnection rules that take into account how, with the right structures in place, solar and solar-plus-battery systems can benefit the grid. The rule revisions introduce a “Limited Generation Profile option,” which will allow solar and battery projects to modulate how much power they send to the grid, according to a chosen schedule, with the help of either solar inverters or batteries. By opting into the regime, projects would avoid paying large interconnection costs for grid upgrades that may not be necessary.
