That’s already the case at grid scale in more expensive markets like California. We’ve been supplementing night time power generation with batteries for years now. Between 5 and 10pm yesterday, batteries supplied more than twice the power that our nuclear reactors did: https://www.caiso.com/todays-outlook/supply https://www.caiso.com/todays-outlook/supply The grid has become so expensive due to the cost of fire proofing infrastructure that residential installs are a no-brainer if you can find someone to do the install for a reasonable price. DIY is even cheaper.

> The grid has become so expensive due to the cost of fire proofing infrastructure Power in California was incredibly expensive long before any of the money was going towards fire proofing.

  There are some very big outlier exceptions to this however. In a handful of markets (such as the city of Riverside) which are served by a nonprofit municipal power authority with its own generation and distribution, local rates are decoupled from the crises plaguing PGE (and to a lesser extent SDGE, etc). residential power costs are substantially lower for customers in these areas vs their immediate neighbors - out-of-pocket power bills are as little as half or a third of for-profit statewide utilities for the same sustained consumption during peak usage times.

> twice the power that our nuclear reactors did Because California forced Nuclear suppliers to throttle down to "make room for renewables", no idea who thought this decision makes any sense.
