Why did China increase ESS capacity in 2021?

In 2021, China saw over 2.3 GW of installed electrochemical ESS capacity, a 50% YoY increase. Among which, 40% was from the generation side, 35% from the grid side, and 25% the end user side. Supportive policy framework is the major driver behind such increases. Many Chinese provinces have set energy storage targets since 2021.

What will China's energy storage capacity look like in 2023?

In 2023, after the substantial rise in annual installed capacity, the growth of grid-connected capacity is expected to slow, increasing by 37.2% year-on-year to 120 GW. As renewable energy installations surge, China's wind and PV curtailment tick up. Given that, several local authorities pose higher energy storage configuration ratio requirements.

Can China achieve energy self-sufficiency by 2060?

Currently, China is still managing to refrain from fossil fuel imports, aiming to reach carbon peak and carbon neutrality by 2060. The long-term solution for China to achieve energy self-sufficiency comprises renewables reaching grid parity and sufficient energy storage capacity.

What percentage of ESS is integrated with renewables?

For the generation side, authorities regulate the percentage of ESS integrated with renewables. Presently, most provinces require renewables to have 10-20% of capacity integrated with ESS that have two to four hours of storage duration.

What are the requirements for ESS in Tianjin Province?

In Tianjin Province, PV system with more than 50 MW of power output shall be integrated with ESS with 10% of the capacity and at least one hour of consecutive storage duration, according to the “Notice of Issues Regarding 2021-2022 Wind and PV Project Development and 2021 Grid Dispatch Guarantees.”

How much subsidy does ESS receive in Northeast China?

In Northeast China, end-user ESS receive RMB 0.1-0.2/kWh of subsidy, on condition that they are subject to the supervision of provincial or higher power electricity dispatch institutions. The subsidized ESS must charge and discharge on demand and are not allowed to charge during peak hours or discharge during valley hours.
