According to this article by smartgridnews.com, the California Public Utilities commission is considering making storage its own asset class. This would allow utilities to offer long term contracts to energy storage companies and developers. Since Steffes Grid-interactive Electric Thermal Storage (GETS) is the low cost electric storage option, setting up storage as its own assets class should create opportunities for GETS programs in California. Analysis by the Cooperative Research network shows the value for electric storage to be between $2000 and $12,000/kW. The cost of GETS space and water heating is between $100 and $200/kW. Setting up storage as an asset class and deploying GETS space and water heating will be provide a positive return for the rate payers in California.
Other states would be wise to explore this as well.
