Behind-the-Meter (btm) Market Growth Factor

High Electricity Prices and Demand Charges

High electricity prices and escalating demand charges are major factors propelling the global behind-the-meter (BTM) market. These rising costs are pressuring both residential and commercial consumers to seek more cost-effective energy solutions.

• For instance, U.S. residential electricity bills have surged 4.5% over the past year, outpacing inflation (~2.2%), largely due to higher natural gas costs, grid modernization investments, and booming demand from data centers and EVs. Similarly, in New South Wales, electricity bills are expected to rise up to 9.1% from July 1, 2025, driven by soaring wholesale prices and the infrastructure rollout needed for renewables.

Such increases make peak demand charges even more burdensome, especially for high-usage consumers. BTM systems, such as rooftop solar and battery storage, enable users to reduce grid reliance, avoid peak-time charges, and manage energy usage efficiently, thereby driving their growing adoption across markets.

Market Restraint

High Upfront Costs and Financial Viability

One of the primary restraints in the global behind-the-meter (BTM) market is the high upfront cost of system installation, particularly for solar panels and battery energy storage systems. These systems require significant capital investment, which can be a barrier for residential and small commercial users, especially in regions with limited financial incentives.

Although long-term savings are possible, the payback period may not be attractive without government subsidies, tax credits, or third-party financing models. Additionally, concerns about the return on investment (ROI) and performance uncertainty further hinder widespread adoption. This financial barrier limits BTM market growth, especially in developing economies with lower purchasing power.

Market Opportunity

Government Incentives and Net Metering Policies

Government incentives and net metering policies are unlocking significant opportunities in the global behind-the-meter (BTM) market. These mechanisms allow consumers to generate their own electricity, typically via rooftop solar, and feed excess energy back to the grid, receiving financial credits.

• For example, in India, the 2024 Rooftop Solar Scheme under PM Surya Ghar incentivizes homeowners with subsidies up to INR 78,000 (~$935), driving residential BTM adoption. Similarly, in the U.S., the Inflation Reduction Act extends a 30% federal tax credit for residential and commercial solar systems until 2032.

These policies reduce payback periods and boost the economic appeal of BTM systems. Additionally, California's updated Net Billing Tariff (NEM 3.0) encourages solar-plus-storage deployment, pushing consumers toward integrated BTM solutions. Such supportive frameworks are expected to catalyze market expansion globally.
