Charging battery storage systems

Battery energy storage systems play an essential role in the net zero transition and we’re helping BESS projects nationwide connect to the grid.

How we can help you

Balancing local network demand

With battery energy storage systems providing a flexible and reliable way to store renewable energy, connecting new BESS projects is fundamental to the UK achieving its net zero targets. We’re supporting the transition by helping battery storage owners and operators seamlessly connect their sites to the grid.

Reducing capital costs

Our competitive asset value contributions can offset the capital cost of constructing the new electricity network on your site.

Flexible design solutions

With innovative and flexible design, we can minimise the footprint of our electricity infrastructure to maximise space for battery racks.

Faster design approval

While it often takes months for regional distribution network operators, we can approve your designs within days.

Accelerating land rights

Our in-house Land Rights team works with third-party legal experts to fast-track the wayleaves and legal process.

Installing your infrastructure

We work with your preferred NERS-accredited independent connection provider, who will install your electricity infrastructure.

Adopting your infrastructure

We adopt last-mile electricity assets up to 132kV, including primary substations, connecting battery storage sites to distribution and transmission networks.

Operating your infrastructure

We provide peace of mind that your supply is secure and reliable with 24/7 remote monitoring and emergency response.

Who we are

About mua

We’re an independent distribution network operator (IDNO), operating electricity infrastructure powering battery energy storage systems.

We’re licensed by the energy regulator Ofgem to adopt, operate and maintain electricity networks that connect battery storage sites to regional distribution networks nationwide.

Unlike local distribution network operators (DNOs), we offer competitive asset value contributions to adopt the new electricity infrastructure at your site.

By reducing your upfront capex costs, our investment could help your project become commercially viable.

Case studies

Our projects

We make utility connections a simple and seamless experience, adding expertise and value every step of the way. As an established multi-utility network operator, we provide electricity, gas and water services that communities rely on.

FAQs

Frequently asked questions

Battery storage helps balance demand on local electricity networks. Typically, the batteries charge overnight when demand on the network is lower. This stops renewable energy from being wasted when it’s not needed and increases energy security.

The stored energy is released back to the grid when demand from homes and businesses is high.

We’re licensed by the energy regulator Ofgem to own and operate electricity networks powering battery energy storage sites. We’ll maintain the new local network for its entire lifecycle.

Unlike local distribution network operators, we offer competitive asset value contributions to adopt new connections to BESS projects.
