Why do we need energy storage developments?
The UK has a legally binding target to achieve net-zero by 2050. This results in many low carbon and renewable developments being needed across the UK. Intermittency of renewables is a key characteristic to manage and overcome, with their dependency on weather and the time of day. Energy Storage Systems, like this proposal, are leading the way in balancing demand and providing flexibility to the supply of electricity in terms of where it can be stored, and when it can be utilised.
Relationship to nearby projects
We are aware of the number and locations of other development proposals and approved developments in the local area and working closely to develop our proposals with them. Our proposal has been positioned to minimise visual effects and planting will be implemented to reduce these further.
The site is close to the Norwich main National Grid Substation, where we have a confirmed grid offer to connect the project to the Electricity Transmission System. We have considered other land in the area and around the substation. We believe the site we have chosen offers the best available opportunity to deliver our project.
We are in discussions with the other developers to allow for co-existence and to look at ways to be sensitive to the surrounding area and residents. This community consultation will provide valuable comments from the residents around the proposal.
Why do we need a new substation?
A new substation is required to allow power to be transferred between the Energy Storage System and the National Grid substation. This equipment would step up / step down the voltage between the sites which would be connected via an underground cable.
How is this project linked to renewable energy generation?
The proposal allows for energy to be stored at times of low demand and released at times of high demand. Renewable energy generation is intermittent, and ESS help to balance that this by storing electricity at times of peak demand. Energy storage allows us to make better use of our existing electricity supplies and for electricity generated from renewable energy sources to be fully utilised.
Will the development emit noise once constructed?
The equipment will emit noise. We are currently working with our Noise Consultants to confirm the most appropriate layout and any mitigation measures to ensure the noise emissions from the site do not exceed background day-time, and night-time, noise levels.
How safe is the ESS?
Energy Storage Systems are a safe and established technology and there are many sites across the UK operating today. The development will incorporate a number of embedded safety mitigation measures to ensure the development operates safely and in accordance with regulatory requirements and the requirements of the local Fire Service.
