Indiana’s energy storage market is growing alongside rapid solar expansion, with increasing deployment to support grid reliability and integrate new generation.
While Indiana’s policy framework for storage continues to evolve, strong solar growth and a large development pipeline are expected to drive additional storage deployment. As utilities expand capacity and modernize the grid, energy storage is likely to play an increasing role in balancing supply and supporting future energy needs.
