Permit Requirements: 

Installing a home energy storage battery system typically requires obtaining permits from local governments, including: 

• Building permits: To ensure that the installation complies with building safety standards. 

• Electrical permits: To ensure that electrical connections comply with regulations and guarantee the safe operation of the system. 

Specific requirements may vary by state or local government. Consult with local authorities before installation to understand the detailed regulations.

Federal Subsidy Policies

Under the Inflation Reduction Act (IRA), the U.S. federal government offers the following subsidies:

• Residential Clean Energy Credit: From 2022 to 2032, eligible clean energy equipment installations qualify for a 30% tax credit, including standalone battery storage systems, without requiring installation alongside solar systems.

State-Level Subsidy Policies

States may offer additional incentives, such as:

• California: The Self-Generation Incentive Program (SGIP) provides subsidies per kilowatt for battery energy storage systems, with additional funding support for high-fire-risk areas and low-income households.

• Connecticut: The Energy Storage Solutions Program offers residential customers up to $16,000 in installation subsidies.

• Massachusetts: The Mass Save Connected Solutions program offers financial incentives and financing options.
