3. Installed utility-scale solar-and-storage will double
BloombergNEF’s database currently tracks 278 utility-scale PV-and-storage plants fully commissioned, with total PV capacity of 12.5GW and battery capacity of 2.7GW / 7.7GWh. We will publish a note on this in February 2022, and expect to need to revisit it frequently as the market expands.
The largest markets this year will be China and the U.S. The U.S. is already a well-established solar-and-storage market. In China, 20 provinces now require or encourage new-build renewables to pair with energy storage.
5. Residential solar and storage becomes the default offering in more than two markets
Residential solar-and-storage will be on the political and investment agenda with greater urgency than in previous years, as it is starting to be a significant sector. In Hawaii, nearly all new residential solar systems are now built with storage; Germany, about half include storage; while in Switzerland about 15% do, and in Australia, about 5%. This figure is not available for most markets, but we expect by the end of 2022, there to be at least two further markets we know of that have more than 50% storage attachment rates.
There is little consistency between countries about rules to incentivize storage or ensure that the storage will be charged and discharged to benefit the grid, or whether solar and storage systems will be sufficient to power a house through a grid blackout. This will change in 2022.
