400 MW of solar projects: Ameren Missouri gains full permission to make a massive acquisition
While possessing money to make purchases is important, completing the purchase is not as simple as putting up the money and receiving it instantly because there are various steps involving the government and the Department of Energy’s approval. A press release from Ameren Missouri revealed that the company is building a stronger, more resilient energy grid for customers after adding facilities that can help meet their needs during periods of high use, including extreme temperatures.
The Missouri Public Service Commission is said to have recently approved the company’s plans to establish the Castle Bluff, Huck Finn, and Millcreek battery energy storage systems and acquire the Ringer and Tom Sawyer solar developments. The completed agreement shows how dedicated the company is to ensuring that the Missouri community has consistent energy availability, especially in situations where generation may not be a reality.
The Missouri-based projects are designed to generate electricity or store energy and deliver it to the grid when customers need it the most, including during extreme heat, cold, and other times of high energy use. The strategy behind the deployment is that it helps the company prepare the grid for how its customers will use energy in the coming years. Battery storage is a particularly important component because it can respond within moments to changing grid conditions and provide extra energy when demand is highest.
