What is a home energy storage system?

A home energy storage system consists of inverters, battery groups, and other energy storage components to create an uninterruptible power supply system for household consumers. This system combines renewable energy and implements load shifting to improve energy quality and bring economic benefits while reducing your electricity bills.

Why should you invest in home energy storage systems?

An unexpected power outage can be inconvenient and disruptive, especially for those working from home. Homeowners invest in home energy storage systems to provide power when needed and store it when not required, integrating with home circuits.

Where can energy storage systems be installed?

In enclosed utility closets and storage or utility spaces. According to the standard, energy storage systems are not allowed to be installed in living areas of dwelling units or in sleeping units other than within utility closets and storage or utility spaces. Currently, there is no such similar requirements in BS 7671.

Why do we need battery energy storage systems?

Combined with rapid decreases in the costs of battery technology and improving incentives for storage projects (notably the IRA), increasing needs for system flexibility highlight the increasing role of battery energy storage systems, or “BESS” projects, in accomplishing global, national and local clean energy and climate goals.

Should storage be located near load centers?

Placing storage near load centers also has benefits where load centers (especially in urbanized areas) are located far from renewable sources (like utility-scale wind and solar generation facilities), resulting in energy losses relating to the generation tie line (or “gen-tie”) from the BESS to the load.

Do state interconnection rules include storage?

Although several states have updated, or are currently in the process of updating, their interconnection rules to include storage and to enable its more time- and cost-efficient integration onto the grid, the majority of state public utility commissions and utilities have yet to reform their interconnection rules to be inclusive of storage.
