Something
you should
know about
Commercial solar and battery storage projects in the U.S. may qualify for federal, state, utility, and local clean-energy incentives. Eligibility and incentive value vary based on project design, ownership, timing, labor, equipment sourcing, location, tax status, and current program rules. CEI primarily serves California while supporting projects nationwide. The information below provides an overview of federal incentives followed by California-specific programs.
NATIONWIDE - FEDERAL CLEAN ENERGY
TAX INCENTIVES
IRC Section 48E provides a technology-neutral Clean Electricity Investment Credit for qualifying clean energy and storage projects placed in service after December 31, 2024. The base credit is generally 6%, with a higher rate available when prevailing wage and apprenticeship requirements are met or an exception applies. Additional incentives may include Domestic Content, Energy Community, and Low-Income Communities bonuses, along with potential transferability or elective payment. Eligibility is subject to evolving timing, sourcing, and foreign-entity restrictions, so project-specific qualification should be confirmed with current IRS guidance and a qualified tax advisor.
FEDERAL TOPICS
• Section 48E Clean Electricity Investment Credit
• Prevailing Wage & Registered Apprenticeship requirements
• Domestic Content Bonus
• Energy Community Bonus
• Low-Income Communities Bonus Credit for qualifying facilities
• Transferability / Elective Pay, where applicable

LOCATION MATTERS
Beyond federal tax incentives, commercial solar and battery projects may be affected by state incentive programs, utility tariffs, interconnection requirements, export compensation rules, demand charges, and local permitting requirements. These programs differ significantly by state and utility territory and can change over time. For this reason, CEI evaluates available programs and utility rules based on the specific project address rather than presenting one incentive structure as applicable nationwide.
CALIFORNIA - SGIP BATTERY STORAGE INCENTIVES
California's CPUC-administered SGIP offers incentives for behind-the-meter advanced storage and solar-storage systems. Eligibility and rebate levels depend on project details, customer type, utility territory, program rules, and changing funding. Since budgets/rules shift frequently, CEI advises project-by-project evaluation rather than assuming a fixed rebate.

CALIFORNIA - SCE SOLAR BILLING PLAN/ NET BILLING TARIFF
For eligible renewable energy systems in Southern California Edison territory under the Solar Billing Plan, customers pay for grid electricity and may receive time-varying credits for exported energy. As a result, load profile, system sizing, time-of-use strategy, and battery storage are key factors in evaluating commercial solar economics.

WHY BATTERY STORAGE?
Business Benefit
Peak Demand Management
Solar Energy Optimization
Energy Resilience
Website Explanation
Battery storage can help shift when a facility draws electricity from the grid and may support
strategies designed to reduce demand during higher-cost periods.
Excess solar generation can be stored for later use instead of being exported immediately,
allowing businesses to use more of the energy produced on-site.
When designed and configured for backup capability, battery storage can support critical
loads during certain grid outages and improve site resilience.
