Network Infrastructure

We’re helping grid operators accelerate the uptake of renewable energy affordably and reliably with large-scale battery storage.

We develop, finance, build and operate large-scale battery storage systems.

We’re helping grid operators move to a fully renewable electricity system affordably and reliably. By enabling them to overcome challenges in balancing supply and demand, power stability and constraints, we’re ensuring network demand and consumer cost expectations are met.

The benefits

How it works

Zenobē is the largest operator of transmission-connected batteries in Great Britain.

We help grid operators transition to a fully renewable electricity system affordably and reliably. By owning and operating the largest portfolio of battery systems on Great Britain’s transmission network, we enable them to balance supply and demand, maintain power stability, and overcome network constraints—ensuring reliability and cost-effectiveness for consumers.

Powering the transition away from fossil fuels

Our grid-connected batteries and services are powering the transition away from fossil fuels and towards net zero. By 2026, we are on track to manage 1.2GW of battery power.

 

Our 300MW Blackhillock project is the largest battery energy storage system in Europe at the time of go-live and the world’s first transmission-connected battery to provide full stability services. It is expected to save over 450,000 tonnes of CO₂ in the next 15 years while reducing consumer energy bills and maximising the use of homegrown renewables.

Amplifying the grid’s capabilities

Our batteries have been the first to provide fast reserve, to be used for reactive power and to manage grid constraints on the transmission network.

 

Our bespoke solutions range from ancillary, balancing and wholesale trading, to providing inertia, short circuit level, and voltage management.

 

We also provide non-wire alternative solutions that reduce or eliminate expensive network reinforcement costs. These are specific solutions that are essential to a decarbonised electricity system.

Delivering savings to the consumer

Our end-to-end solutions cut the need for expensive or time-consuming grid upgrades, facilitating a reliable and affordable electricity network.

 

We design, build, finance, maintain and decommission all our projects. And by partnering with financial institutions, we gain access to more competitive financing.

 

The combined result is that the end consumer gets a lower bill. And the proof is in our track record – we have  multiple large-scale projects that validate this.

Maximising the uptake of renewables

01.

Identify

Identify strategic locations and specific grid challenges where large-scale battery storage can provide reliable and cost-effective solutions for grid stability and renewable integration.

02.

Analyse

Conduct detailed site assessments, grid impact studies, and technical evaluations to design bespoke battery solutions tailored to local grid needs.

03.

Design

Create custom battery storage solutions including engineering design, planning, and optimisation of battery systems for grid services such as reactive power, frequency balancing, and short circuit support.

04.

Build

Manage the full project lifecycle from procurement and construction to integration, ensuring that each battery system meets the highest standards of safety, efficiency, and performance.

06.

Operate

Deliver operational management of battery assets, including real-time monitoring, grid support services, and maintenance to maximise asset value and grid reliability.

07.

Decommission

Develop and execute decommissioning strategies that minimise environmental impact and enable repurposing or recycling of battery components.

Batteries provide a range of different services to power networks, including maintaining grid stability, managing frequency, voltage, and short circuit level.

 

Renewable energy is intermittent which means that at any time there is a risk of generating too much or too little in relation to demand. This is where batteries come in – storing energy when there is an oversupply and releasing it when there is not enough.
