The Proposal
The Proposed Achies BESS
The Achies BESS project aims to provide a reliable energy storage solution near the Spittal Converter Station.
Location
To be situated on land to the northwest of the existing Spittal Converter Station. Sun4Net has an agreement to connect the Achies BESS to the existing Converter Station in July 2027.
Key Elements
- Battery energy storage units (around 70 in total, subject to final design)
- A dedicated substation
- Underground cable to connect the BESS to the existing Spittal Converter Station
- Site access tracks for maintenance and emergency vehicles
- Drainage infrastructure
- Safety and protection systems
- Landscaping and biodiversity enhancements
Capacity
The BESS will have the ability to store and discharge electricity as needed, supporting grid stability. The proposed export capacity of the BESS is 162 MegaWatts (MW). To put this into context, 1 MW will power 2,000 homes for 1 hour, based on average UK electricity consumption1.
1 What is the difference between a megawatt and a megawatt hour?
Environmental Considerations
The project will undergo rigorous environmental assessments to minimise impact and enhance biodiversity where possible.
Safety
Safety is a top priority for the Achies BESS project. The system will incorporate industry-leading fire detection and suppression technologies to mitigate risks. Comprehensive fire safety measures, including thermal monitoring, emergency response plans, and strict adherence to regulatory standards, will be implemented to ensure the highest levels of safety.
Keeping you informed
We are committed to keeping local communities informed and involved throughout the development process.
