Access a limitless supply of clean, renewable power whatever the weather or time of day.

Faced with the challenge of intermittent power from renewables, Zenobē provides a range of services that stabilises the grid for transmission and distribution operators. We design, finance, build and operate grid scale battery storage sites that keep the lights on as we transition to a zero-carbon power system.

Our solutions are making a world without fossil fuels a reality and we are well on the way to having 1GW of battery storage in operation by 2025.

Providing flexible power services

We are world leaders in helping grid operators deliver clean energy safely, reliably and affordably. Through our innovative use of battery storage, we help deliver a flexible power network, balancing the supply and demand of renewable power and enhancing the grid’s capabilities.

  • A reliable, affordable renewable network without the need for expensive and time-consuming grid upgrades
  • Access to world class active and apparent power services and track record of successful projects

Our bespoke services range from:

  • Ancillary, balancing and wholesale trading
  • Providing inertia
  • Short circuit level and voltage management
  • Non-wire alternative solutions to reduce/eliminate expensive network reinforcement costs

Delivering financial stability & affordability

We make it easy, reliable and affordable. We manage the full solution that we develop for our customers, removing the financial and operational risk.

  • A strong track record and depth of expertise over multiple large-scale projects in the UK
  • We manage, design, build, finance, maintain and decommission all our projects
  • Access to competitive financing delivers substantial savings for our customers
  • Ultimately, this helps lower bills to end consumers

Leading the charge

We’re leading the charge with 225MW of battery storage in construction or operation, backed by an experienced team of engineers, data scientists and software developers.

Our 100MW Capenhurst project is the largest transmission connected battery site in Europe. It’s a glimpse into the future for power networks around the world.

  • We were the first battery owner and operator to provide reactive power, Fast Reserve, short circuit and inertia services in the UK
  • We’re constantly innovating, learning and developing battery and power electronics solutions to meet changing needs of grid operators in the UK and abroad
  • We’re on track to have 1GW of battery storage by 2025, powering the UK to a zero carbon electricity system



Why is battery storage important?

We provide the flexibility to decarbonise our energy system. This is fundamentally important to a zero-carbon future.

  • Our 100MW Capenhurst site will save over 1m tonnes of CO2 over 15 years
  • 590 GW of global battery storage is required by 2030 to be well on the path to net zero alone.[1]
  • Battery storage can stabilise renewable generation, increase its affordability and reduce our reliance on fossil fuels

Capenhurst 100 MW battery: A world first

Zenobē is building the first battery to absorb reactive power direct from a transmission network in the world. It will also be the largest transmission connected battery in Europe.

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.
