Technical FAQs 4

What is grid-scale storage?

Grid-scale storage refers to technologies connected to the power grid that can store energy and then supply it back to the grid at a more advantageous time – for example, at night, when no solar power is available, or during a weather event that disrupts electricity generation.

Should energy storage be removed from energy grid connection?

For energy storage, the new Chinese policy emphasized the need to remove energy storage as a prerequisite for renewable energy project grid connection, a requirement that has been a major driver for battery build. Nonetheless, BNEF still expects strong demand for batteries, as the policy doesn’t explicitly require mandates to stop.

What is China's energy storage policy & regulatory roadmap?

The policy and regulatory roadmap is aimed at pushing China’s installed base of large-scale energy storage – primarily lithium-ion battery energy storage systems (BESS) – to 180GW by the end of 2027.

Are startups repurposing EV batteries for grid-scale storage?

Startups have been taking note. Redwood Materials, which was co-founded by Tesla alumnus JB Straubel, in June added a new business line focused on repurposing used EV batteries for grid-scale storage.
