It's no longer expensive. And it has benefits. >A report by McKinsey and Co presented at the recent Australian Energy Week conference claims that Tesla's 100 MW / 129 MWh battery has now reduced grid service costs by 90%, taking over a 55% share of state's Frequency Control Ancillary Services (FCAS).

Combined into "clean energy portfolios," these resources can "provide the same services as power plants, often at net cost savings.” [1] https://www.utilitydive.com/news/end-of-the-gas-rush-renewables-storage-reaching-cost-parity-report-fin/524840/ https://www.utilitydive.com/news/end-of-the-gas-rush-renewab... >Solar-plus-storage projects could be competitive without any federal tax incentives in California by 2020, Paul Denholm, senior energy analyst at the National Renewable Energy Laboratory (NREL), told Utility Dive. Denholm added that the time is not far off when these project pairings will be competitive with gas-fired peaking plants in other locations such as the Southwest. >"Solar-plus-storage could be competitive in a sizeable fraction of the United States, but it is hard to say exactly when, mostly because of fluctuations in the cost of natural gas," Denholm said.
