Technical FAQs 4

Are energy storage systems safe?

Within a given technology (e.g., lithium ion), there can be large differences in system performance based on the specific cell chemistry. For all of the technologies listed, as long as appropriate high voltage safety procedures are followed, energy storage systems can be a safe source of power in commercial buildings.

Do you have to grapple with code for energy storage systems?

2023 NEC Updates for Energy Storage Systems Whether you are an industry veteran or a DIYer out over your skis, you'll have to grapple with code if you want to install an energy storage system (ESS). More specifically, you’ll have to grapple (metaphorically, of course) with your local inspector.

Is energy storage a viable option?

Assuming the initial analysis shows that energy storage is an economically viable option, the final decision to procure an ESS needs to be taken in the broader perspective of the business as a whole. This can include looking at issues of space, noise, and timing for system installation.

Can EV battery storage help balance power supply and demand?

Leveraging a two-way flow of electricity from EV battery storage to balance power supply and demand could also help global efforts to integrate more renewables in the power mix. EVs can charge when renewable energy generation from wind or the sun is high or when there is lower demand for electricity ( e.g. when people are sleeping).
