We’d love to get your feedback once you’ve read through our proposals. A digital feedback form for the project can be found here



Built for an era of coal and gas fired power stations, the existing UK electricity network needs upgrading to support the deployment of renewable, low carbon energy. The inflexibility of the network is adding costs to bills and failing to deliver the emissions reductions needed to prevent climate change.
3.4 TWh of electricity from wind turbines lost in 2022 due to a lack of storage on the electricity grid
Equivalent to 5 days power for the whole of the UK
£210 million of payments to wind turbine operators for lost revenue
£590 million of payments to gas-fired power plants to generate electricity equivalent to that lost from wind turbines
1.3 million tonnes of unnecessary CO2 emissions from gas-fired power plants due to a lack of storage

Batteries solve one of the biggest challenges facing renewable energy. Matching weather dependent solar and wind electricity with household and business electricity demand.

Currently, gas power plants are turned on to supplement wind and solar energy supply and meet peak electricity demand between 7 and 9am and 6 and 8pm

Batteries maximise the amount of renewable energy we can use at home and reduce the number of times we need to turn on a gas fired power plant to meet peak demand, saving money and reducing GHG emissions

Weather dependent wind and solar energy farms often produce more energy than is needed to meet electricity demand overnight and at off peak times during the day

With both supply and demand fluctuating across the day, batteries store energy when there’s more than needed to meet demand and discharge it when there’s less than needed

Example Battery Storage Facility

The total site area for the project is fixed at 18 hectares with the battery facility accounting for 7 hectares. Connection to the electricity grid would be via underground cable along Warley Street and Clay Tye Road. The plan below shows an example of what the final scheme could look like. With the feedback gained from this public consultation we will work up a final design for submission to Havering Council as part of our planning application for the project. This example design ensures that more than half of the site is managed for screening and biodiversity benefits and we anticipate the final design will deliver a similar ratio of electrical infrastructure to landscaping and ecology development.


The Warley Energy Hub would generate £50,000 of funding annually to support community initiatives such as

community icon
Community led projects

Support for community projects focused on improving community services and facilities, enhancing nature and increasing access to open spaces.

Tackling fuel poverty

The implementation of energy saving measures for low-income households that help permanently reduce bills and carbon emissions. In Havering 11% of households are in fuel poverty.

solar panel icon
Low carbon retrofits for local community buildings

Support for installations of solar panels, heat pumps and batteries at communituy buildings.




Wetland Area – Sustainable drainage scheme incorporating an attenuation pond to manage rainwater run off from the site and incorporation wet meadow and pond mixes/planting and shelving for added biodiversity

Meadow – Species rich wildflower meadow mosaic with native scrub planting and tree planting

Scrub and tree screening belt – Native woodland buffer planting, copses and connecting Green Infrastructure planting – Including species which are found in neighbouring woodlands

Further project detail

  • 3 metre maximum height of batteries and associated equipment
  • 14 metre maximum height of substation cable supports
  • Electricity grid connection by underground cable to Warley substation
  • Temporary 40 year use with restoration to agriculture following
The right location

The Warley substation plays a key role in ensuring electricity supply to homes and businesses in Havering and Thurrock. Adding battery energy storage to the electricity grid here will increase the availability of renewable energy locally and provide greater security of supply.

The project would be built adjacent to existing rail infrastructure, distant from local homes and with minimal impact on the local community.

Safe by design

The indicative site layout meets or exceeds safety standards set out by the UK National Fire Chief Council and US National Fire Protection Agency. The London Fire Brigade will be consulted at all stages in the development of the project. Please read this blog from Blesson Thomas, Head of Grid at Clearstone Energy, for more information on our Battery Safety by Design approach.

Frequently asked questions

No – while the facility would generate some low-level electrical noise from the inverters, switchgear, and fan equipment this noise would not be perceptible beyond the site boundaries. To demonstrate this, a Noise Impact Assessment will be submitted as part of any future planning application.

All Clearstone projects must comply with the standards set out in our comprehensive Battery Safety Standards Plan. Our safety plan draws on best practice from the UK’s National Fire Chiefs Council (NFCC) and the US’s National Fire Protection Agency (NFPA). These standards cover all aspects of the project – technology, site design, installation, operation and emergency response plan – to ensure that it meets the highest safety levels. The London Fire Brigade will be consulted on the project at all stages of its development and operations.

No, this would be a temporary 40-year use of the land, with batteries, other equipment and hard infrastructure removed at the end of the project and the land returned to agricultural use.

Battery units are prefabricated offsite rather than assembled in situ. On site construction will be restricted to the laying of shallow concrete pads for battery containers to sit on and the craning of prefabricated units into position ready for cabling and connection works. As such, project construction would take 12-15 months.

The Lithium-Ion batteries that will be used in the project are not reliant
on scarce raw materials. There are established recycling processes for recovering the most common elements used in battery construction – iron, phosphate and lithium – for re-use.

Typically, there would be two HGVs a day bringing prefabricated units to the site during construction. Construction vehicles will route to the site via the M25, A127 and Warley Street. Once operational, traffic would reduce to a light goods van visiting a couple of times a month.

No, there will be no lighting on site.

The maximum height of the batteries would be 3m. However, these would be screened by existing hedgerows and new woodland and hedgerow planting.

Clearstone Energy is a leading independent developer of renewable energy and energy storage projects that increase the availability of clean energy and improve the resilience of the electricity grid.

We are working with National Grid to develop solar generation and battery storage projects that are building a UK energy system based on clean, low cost and renewable energy.

Our experienced team has a track record of developing successful renewable energy projects that are providing clean and reliable energy to communities across the UK.

Since founding in 2016, Clearstone Energy has developed eleven energy projects in the UK. Two are operational and nine are in or awaiting construction.

We believe that our projects can do more than energy generation and storage. They support the adoption of renewable energy and energy efficiency technologies in the communities that host them. They provide opportunities to build habitats for wildlife and contribute to the preservation of local ecosystems. They provide support for community projects.

    Solar Energy

    The UK’s energy markets have experienced turmoil and rising electricity costs since 2021, leading to a surge in rooftop and ground-mounted solar installations in 2022. Two-thirds of UK solar generation comes from large-scale projects, and solar energy is the fastest growing and lowest cost renewable energy technology.

    More about Solar

    Battery Storage

    Battery energy storage is key for reliable renewable energy. Large scale batteries near wind and solar sites ensure a constant electricity supply. Transitioning from gas to batteries will make energy cleaner, more secure and cheaper. In 2022, UK wind farms were paid £62m a day to not produce power because of the lack of storage, which cost consumers.
