Wind Solar and Storage Industry Cluster

What are the biggest solar and storage projects in the US?

One of the biggest solar and storage projects underway in the U.S. is Longroad Energy’s Sun Streams Complex in Arizona, totaling 973 MW of solar and 600 MW/2.4 GWh of battery storage capacity. After the first two phases began operations in 2021 and 2024, the fourth and largest project is underway with 377 MW of solar and 300 MW/1.2 GWh of storage.

How does wind and solar integration affect battery development?

Voltage instability and decreasing grid inertia have emerged as significant side effects of growing wind and solar integration, shifting the market towards grid-scale storage solutions to balance supply and demand. Last year, the EIA estimated that developers would bring more than 300 utility-scale battery projects online by 2025 (9 GW).

Are land-based and offshore wind projects in demand?

Land-based wind projects are in demand in the U.S., while offshore wind is gaining traction in the U.K. and Europe. The latest projects incorporate next-generation solar and wind components as manufacturers expand their performance and efficiency to meet market demand.

How many solar projects are under construction?

In the U.S., more than 112 GW of large-scale solar projects are under construction or development, according to a database from the Solar Energy Industries Association. Most utility-scale and commercial solar projects slated to come online in the next few years have already secured an interconnection agreement or started construction.

How many homes can a wind turbine power?

When it becomes operational in August 2025, it will deliver enough power for 83,000 homes. The company has assembled all 88 turbines, and operations are expected to begin in August 2025. A future phase could add more wind units and a lithium-ion battery storage installation.
