Cheaper Battery Storage Enabling ‘Anytime’ Solar, Ember Says

Batteries are getting cheaper and allowing solar power to be used beyond daylight hours, according to new analysis from clean energy think tank Ember.

The costs of building giant, utility-scale batteries globally have declined significantly in recent years — including a 40% drop in 2024 — and have room to fall further, the report released on Thursday showed. This in turn has lowered the cost of storing solar for use anytime to $76 per megawatt-hour, a highly competitive level against new fossil fuel generation.
