The Connected Timeline


E-STOr prototype

First proof of concept

Our first demonstrator project took place with partners Lotus Cars, Circontrol, APT Technologies (now SWARCO) and GoodWolfe with funding from DECC. The demonstrator used six different battery types and linked energy storage to a micro-wind turbine, solar PV and EV charge points.


Open day at Cranfield University

Collaboration with Renault Group

Our long-term relationship with Renault Group was established, marking the start of an electrifying adventure. We began by first incorporating batteries from the Renault Fluence into our systems and later batteries from the Renault Kangoo.

Pre-production prototype

In an Innovate UK project, the company worked with EDF Energy to develop our first prototype. The system developed was installed at York City Council’s eco depot linked to PV and EV charge points.

Award winners

The team also scooped two awards this year: the Renewable Energy Association’s Innovation award and the EDP Enviro-Technologies award.


First commercial order

Our first 60kW/90kWH system was delivered to Statkraft in the UK. It was controlled using their virtual power plant which allowed them to operate the system according to energy forecasts from their trading desk.

Fastest growing businesses

Connected Energy was named in the top 100: Britain’s Fastest Growing Businesses by the Syndicate Room. The report identified the companies that had increased in value the most during the year.


Integration with European EV charging hubs

Working with Renault and Allego in Belgium and Germany, our systems were installed along the Fast-E corridor to actively manage grid capacity constraints on the network of 50kW charge points.

Technical Centre expansion

As the company began to expand, we opened our new technical centre in Hethel, Norfolk – the heart of our technical R&D.

Energy Management Software

Our back-office software

We developed our first iteration of our cloud based software which now provides integral support to our systems and services, providing reporting and monitoring visibility to our customers.


£3 million investment round

Investment from Macquarie Group and ENGIE New Ventures allowed us to begin to realise our growth plans.

Innovate UK 2nd hEVen project

With funding from Innovate UK and a collaboration with Jaguar Land Rover and Warwick Manufacturing Group, we proved that our technology could be adapted to use second life Jaguar I-Pace batteries.

UK’s first EV charging hub

Working with Evolt (now SWARCO), we were appointed to supply our system to support Dundee City Council’s EV charging hub. The system linked solar PV to several rapid chargers at the flagship site.

1.2MW system proof of concept

A partnership project with investor, Engie, saw a 1.2MW system installed at Umicore’s recycling plant in Belgium. The system demonstrated the technical and economic viability of combining the system with other assets to provide frequency response services.


£5 million investment round

A further investment round was secured bringing £5 million investment from Sumitomo Corporation, ENGIE, Macquarie Group and others.

Winner of the Japan Energy Challenge

The awards recognise Europe’s most innovative energy sector SMEs.


Launch of our 300kW/360kWh system

The Hold, a flagship heritage facility for Suffolk, chose Connected Energy to supply our next generation system. The system allows the site to optimise energy and manage peak loads across a network which includes PV, EV chargers and HVAC.

New financing models

Working with Capitas, we introduced new finance models to minimise upfront investment required from businesses.

Study proves second life is best

An academic study with our partners, Lancaster University, addressed the issue of the carbon impact of second life EV systems. The study concluded a 450t CO2 savings per MWh over the life of the battery for second life systems.

More awards for Connected Energy

The team picked up both the PLMA Technology Pioneer award and the North East Automotive Alliance’s award for Innovation.


Solar PV battery storage

Three systems installed at Cranfield University

Our most sophisticated behind-the-meter order so far, Cranfield University will use three systems working collectively to support a solar farm, air source heat pump and waste management centre.


£15 million investment round

A further highly successful round of investment brought Caterpillar Venture Capital Inc., the Hinduja Group, Mercuria, OurCrowd and Volvo Energy. The investment is enabling the company to scale-up its operations.

Developing AI with NIC-D

The company has worked with Newcastle University’s National Innovation Centre for Data for several years to embed new data science skills into our product. Ground breaking research in 2022, proved the ability to embed AI and machine learning in our software to monitor and predict battery performance.

Scaling for the future

Work begins on our first in-house financed utility scale system.


Matthew Lumsden, Nigel Dent and Alex Charr, all of Connected Energy, sign a letter of intent with Volvo Energy

Volvo Energy and Connected Energy announce joint ambition

Volvo Energy has signed a Letter of Intent with us to build upon a joint ambition to develop a battery energy storage system. We intend to build BESS with batteries recovered from Volvo electric buses, trucks, and machines, creating a second life for the batteries, and delivering significant environmental and economic benefits.

Successful E-STOR Data Validator project concludes

We have developed scalable data management processes, and the Flexible Control Architecture created will form the basis of all of our future products after a successful three-year implementation of £1.2m funding with Innovate UK and Engie (now Equans).

Numerous new installations

We have installed several battery energy systems across the UK including North Tyneside Council, Dundee City Council, University of Bristol, Glasgow City Council and West Suffolk College.

Connected Energy team expansion in 2023 with 18 new employees

Significant company expansion as a result of project successes

We have welcomed 18 new faces into the business in 2023 as a direct result of project wins and upcoming opportunities requiring additional expertise, and we’ve also implemented numerous staff benefits including an EV salary sacrifice scheme.
