New Hampshire Energy Storage Policy and Market Overview

New Hampshire’s energy storage market is comparatively nascent to regional neighbors. However, state legislative and regulatory guidance on storage is prioritizing a cost-effective deployment with several ownership models.

New Hampshire regulators, NGOs, and utilities provide various energy storage incentives to stimulate market competition and evaluate BTM ownership models. State incentives modelled after ConnectedSolutions indicate the diffusion of energy storage policy and the success of market-based rebates. In evaluating ownership, the PUC and Liberty Utilities developed a first-of-its-kind pilot program installing five hundred home batteries to assess BTM storage efficiency and effects on customers’ bills.

Despite limited regulatory guidance on energy storage the BTM market is accelerating with tax and utility incentives. Legislative action via HB 464 (2019) allows municipalities to adopt property tax exemptions for energy storage, leaving open more opportunities for reduced system costs for homeowners and businesses.
