Should you invest in a commercial battery storage system?
Investing in commercial battery storage systems now offers benefits such as shorter payback periods, energy independence, reduced peak power costs, and achieving sustainability or carbon neutrality goals faster. Additionally, government incentives make systems more affordable.
How long does a battery last?
By the end of its design life, the electricity delivered by the battery will be lower due to degradation. Manufacturers typically guarantee ≤2 % annual fade, meaning after 20 years, capacity remains at around 65% of initial usable energy. Higher cycling leads to faster degradation and a shorter lifetime.
How can government incentives help a commercial energy storage system?
Government incentives, such as tax credits, rebates, and grants, can significantly lower the upfront costs of commercial energy storage systems. In the U.S. and Europe, businesses may receive tax credits of up to 30% of the system cost, making the investment more financially viable.
