Policy and Regulatory Landscape

Government policies and regulations play a pivotal role in shaping the energy storage market. Many jurisdictions are implementing policies to incentivize the deployment of battery storage, such as tax credits, subsidies, and mandates for energy storage integration. The Federal Energy Regulatory Commission (FERC) in the United States, for example, has issued orders aimed at removing barriers to energy storage participation in wholesale electricity markets. State-level policies are also driving growth, with several states setting ambitious energy storage targets. However, the regulatory landscape can be complex and vary significantly across different regions, creating challenges for investors. Clear and consistent policies are essential for fostering investor confidence and accelerating the adoption of battery storage technologies. These policies must also reflect the unique characteristics of energy storage, such as its ability to provide both energy and ancillary services to the grid.

The Impact of Renewable Portfolio Standards

Renewable Portfolio Standards (RPS) are state-level policies that require utilities to source a certain percentage of their electricity from renewable energy sources. These standards are a major driver of renewable energy development and, consequently, increase the demand for energy storage. As utilities increase their reliance on intermittent renewable energy sources to meet RPS targets, they need battery storage to balance the grid and ensure reliability. The stringency of RPS targets and the inclusion of energy storage as a qualifying resource under RPS programs significantly influence the deployment of battery storage. A more aggressive RPS and broader eligibility for energy storage can create a more favorable investment climate. The benefits that energy storage provides to the grid as a whole – in terms of resiliency, cost savings, and pollution reduction – are also becoming widely recognized by policy makers.
