Seth Mullendore, vice president and project director for Clean Energy Group. The battery storage market for homes and businesses has been steadily growing over the past few years, driven by falling battery prices, demand for reliable backup power and the potential to cut energy expenses. However, the uptake of customer-sited battery storage has not been equally distributed across geographic regions or customer types, with higher-income households driving residential sales and larger energy users with high utility demand charges leading the commercial sector. This has left many behind, particularly lower-income households and small-commercial properties, like community nonprofits and affordable housing providers.
