How much ESS capacity does China have in 2021?

Installed ESS capacity in China has grown every year, as the country pledges to achieve net-zero by 2026, and with installed renewable energy capacity continually increasing. In 2021, China saw over 2.3 GW of installed electrochemical ESS capacity, a 50% YoY increase.

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.

How can China achieve energy self-sufficiency?

The long-term solution for China to achieve energy self-sufficiency comprises renewables reaching grid parity and sufficient energy storage capacity. Over the past decade, China has been laying the groundwork, becoming a world leader in PV, onshore wind, and lithium battery industries.

What types of energy storage installations are there in China?

Clearly, the predominant types of energy storage installations in China at present are still mandated installations for renewable energy and standalone energy storage. The primary driver behind the surge in domestic energy storage installations is the mandatory installation requirements.

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.

Why is China becoming a world leader in PV and onshore wind?

Over the past decade, China has been laying the groundwork, becoming a world leader in PV, onshore wind, and lithium battery industries. The most prominent outcome is the drastically reduced production costs of PV, onshore wind, and electrochemical energy storage systems.
