Network Infrastructure

We develop, design, finance, own and operate turnkey grid scale storage systems to overcome power challenges.


Zenobe is a world leader in helping transmission and distribution operators transport clean energy safely and affordably. We help manage the mismatch between the rapid uptake of intermittent renewables and the latent capability of power grids.

Our services range from ancillary and balancing services to providing inertia, short circuit level and voltage management. We also provide tailored Non Wire Alternative solutions to reduce or eliminate network reinforcement costs.


Zenobe designs, build, owns, maintains and decommissions all its battery facilities. We bring the first battery owner and operator to raise debt on merchant revenues in the UK for example.

Depending on the mix of services, counterparties and contract duration, Zenobe is able to access highly competitive finance. We pass on this low cost of capital in the fees we charge for our services, so providing excellent value for consumers.

Given the depth of expertise and our proven track record, Zenobe is considered a highly credible and reliable counterparty by our finance partners and our clients.


The Zenobe team is continually looking for new ways to identify, develop and exploit new hardware and software solutions that add value. In doing so, we take on the design, technology and operating risk, so leaving our customers to focus on what they do best.

Zenobe was the first in the world to provide reactive power services on both a transmission and a distribution network. We were the first battery owner and operator to provide Fast Reserve services in the UK. Our engineers, data scientists and software developers partner with innovators, academics and our supply chain to apply proven technology in novel ways that overcome the challenges of non-synchronous generation.

The benefits of Zenobe solutions

  • Access to world class active (frequency, balancing, reserve power and inertia) and apparent (short circuit level and reactive) power services
  • Avoidance of all design, construction, financing, maintenance and decommissioning risks
  • Reduction or elimination of grid reinforcement Capex costs
  • Lower grid Opex costs and substantial savings for consumers
  • Environmental benefits from dramatic reduction in carbon emissions

Capenhurst 100 MW Battery: A World First

The Challenge

The demand for reactive powers services to help manage voltage levels is growing due to the rapid uptake of renewable power generation. As part of its Pathfinder programme, National Grid, the UK’s Electricity System Operator (ESO), conducted a tender for the provision of reactive power in the Mersey region of the UK. This gave an opportunity for new technology businesses to demonstrate how their solutions deliver better outcomes for the environment and consumers than traditional providers.

Zenobe's Capenhurst project will be the first battery to absorb reactive power direct from a transmission network in the world.

The Solution

Zenobe’s specialist high voltage engineering team worked with our supply chain partners to optimise not only the absorption of reactive power but also active power services that run concurrently. This innovative design, which included a direct connection onto the 275Kv bay, has enable the stacking of multiple active power, capacity and voltage services to deliver the lowest cost to the consumer and to make a significant reduction in carbon emissions. Zenobe’s solution results in minimal impact on the environment and local community whilst also adding several habitat enhancements.

Zenobe won a nine year contract to deliver 40MVar of reactive power services in May 2020. This was the first time a battery has delivered this type of service anywhere in the world.

Later, we were the first to use the revision to England’s planning regime for generation assets to build a 100MW facility which is also Europe’s largest transmission connected battery when commissioned in early 2022.

The Capenhurst site will ensure secure of power supply for the Mersey region with a reactive power service delivered at substantially lower cost to consumers. Over the next 15 years it is forecast to remove 1,004,040 tonnes of CO2 compared to traditional sources. This project is a significant milestone towards enabling not only a zero carbon power system but also the delivery of UK’s Net Zero commitments.
