What is the future of energy storage systems for homes?

The future of energy storage systems for homes is bright, with advancements in battery technology, smart grid integration, AI-driven optimization, and affordable pricing making ESS more efficient, accessible, and sustainable.

Why is battery storage important?

• Battery storage is an important enabler of the energy transition, and residential batteries are a major part of that (Figure 1). Already in Germany and Italy, over 70% of new home solar systems have batteries attached, to shift the use of daytime solar power generated to the evening (Figure 2).

Why is residential battery uptake a major market?

Residential battery uptake in major markets began mainly as a result of battery storage subsidies. Other key factors that have driven uptake in some markets are the phasing-out of PV export frameworks, which reduces incentive to export excess solar generation, as well as customer interest in back-up power.

Do residential batteries play a role in the capacity market?

Participation of residential batteries in the capacity market is typically led by retailers with large virtual power plant portfolios. These are mainly for demand response, where residential batteries play a small part.
