US$100 million of that came in the final quarter of the year thanks to the company’s gravity energy storage expansion and ahead-of-schedule execution of a 275MWh battery storage project in California.

The company expects its first commercial EVx system project in China, which uses its gravity-based solution, to start commissioning of all electronic and power generation components in the second quarter of 2023.

Battery storage engineering, procurement and construction (EPC) projects secured last year with Jupiter Power, Wellhead and NV Energy are all scheduled to be online in the second half of 2023.

Over the course of 2022 it contracted and signed booked orders totalling 1,635MWh of energy storage capacity across its technology areas, representing US$540 million of business.
