As an historic first, the Arizona Corporation Commission has voted not to acknowledge the gas-heavy energy resource plans of utilities, and is pushing instead an aggressive clean energy plan by one if its members.
Utility Hawaiian Electric has announced the start of operations of a pilot project featuring flywheel energy storage technology provided by Amber Kinetics. The project will test the technology’s capability of supporting the grid and allowing further integration of renewable generation.
The state is expecting nearly 400 MW of additional utility-scale solar by this summer, as the most significant source of new generation to help it meet summer peak capacity needs.
Scientists in California have modeled a solar-heavy/wind power electricity grid, without nationwide HVDC, that could reliably deliver 80% of U.S. electricity needs. 100% of needs would require 3 weeks of energy storage.
CPUC’s guidance calls for an additional 9 GW of solar and 2 GW of battery storage as the standard against which to compare utility and CCA Integrated Resource plans, and says that new fossil fuel plants must prove a need.
Latest report by IEEFA showcases nine case studies among the world’s leading states by wind and solar market share, which can help up as an example for other countries on their energy transition pathways.
A ruling by CPUC opens the door for “stacking” the services that batteries and other forms of energy storage can provide.
An abundance of hydroelectric power and wind is pushing up renewable energy in the spring months, but there is a need for more power during the summer peak, as well as issues with the geographic location of resources.
CPUC has turned down a request by Calpine for lucrative contracts for three gas plants and ordered PG&E to hold a solicitation for energy storage and/or “preferred resources” instead.
