The Hold - United Kingdom

Application

E-STOR optimising energy use and peak loads across a system including PV, EV chargers and critical HVAC.

The first installation of Connected Energy’s new generation of optimised energy storage systems.


Opportunity

As part of an approved capital project, Suffolk County Council (SCC) (the awarding authority) were looking for a company to design, procure, ship, install, test, and commission a turnkey Battery Energy Storage System (BESS) for the newly constructed heritage centre for Suffolk, based in Ipswich (known as The Hold).

SCC’s primary objectives for the project were to consolidate the council’s formal commitment to be carbon neutral across its estates and operations by 2030, while generating cash savings and revenue opportunities for both themselves and the University of Suffolk (UoS), who are key partners in both The Hold and the BESS project. SCC also wants to generate evidence-based learning on ‘what works’, to inform future energy planning across the council, working in conjunction with the university’s Sustainability Institute, and other local authorities through the Suffolk Climate Change Partnership.

The final objective involves developing the council’s knowledge base on the effective operation of sustainable technology, supporting UoS research and training in clean tech solutions and raising the profile of the region for innovation in this area.

The council is pleased to be working with the University of Suffolk and Connected Energy, and providing access to the BESS to ‘seed’ new research and innovation activities within this sector.

Solution

Connected Energy worked with SCC throughout the building design process and created an E-STOR energy storage system to help optimise both energy use and peak loads - across a scheme including PV, EV chargers and critical HVAC, designed to support the consistent delivery of a controlled climate for the unique archive materials, and to manage running costs.

The system facilitates Dynamic Firm Frequency Response (DFFR) and Capacity Market (CM) services. It also provides TRIAD and capacity market avoidance
alongside DUOS savings.

The new 300kW/360kWh E-STOR system installed at The Hold includes a range of enhancements built on learnings from the systems Connected Energy
has installed over the last five years. Benefitting from collaborative support from Renault and Hitachi ABB Power Grids to increase efficiencies on both the power and capacity sides of the system.

As part of The Hold project Connected Energy is working with the University of Suffolk on a knowledge exchange partnership which supports research and innovation activities across both organisations. The collaboration allows access to the battery storage system for teaching and research purposes, as well as projects to translate university science into practice.
