Case Studies

AEMS is helping small and independent businesses across the UK to change the way they use and view their energy. We have been working with businesses to guide them through the installation process and give them access to the tool. Here’s how it has helped a chain of Co-operative convenience stores…


The Co-Op is gaining a better understanding of the role energy plays within their stores.

Chelmsford Star Co-operative Society operates 40 convenience stores across Essex. Since 1867 Chelmsford Star have provided Chelmsford and the surrounding areas with all of their convenience shopping requirements, offering goods such as freshly baked bread, groceries, through to Fairtrade and Local Food products.


Knowledge of which energy-intensive stores to target and insight into business operations.

AEMS is helping the Co-Op to better understand usage across each of their sites and in turn this has given greater insight into how each of the stores are operating. Being able to benchmark stores against one another helps to target high-energy users and look at ways in which energy can be reduced.

The AEMS benchmarking analytics identified the highest energy-intensive Co-op store. Compared to the other 40 stores, they use nearly twice as much energy as the average store contributing 5% to the overall estate consumption.

“The energy reports were really interesting; they added a new perspective to the stores and gave me lots to think about”

AEMS highlighted that the highest energy consuming store had produced 111,321.90 kg1 of CO2 since 2018, this is the carbon equivalent to making 1.4 million cups of tea in a year.


Staff engagement and a way to manage energy across the chain is challenging.

Chelmsford star were looking to increase staff engagement in-store and gain greater visibility of how their estate uses energy. And, although the company has access to half-hourly energy consumption data, they needed a way to visualise this data so that it is more accessible to the staff in-store and management team.

As a company, they have always tried to be mindful of their energy usage. They review data across each of the stores and where possible have taken action to try to reduce this. Investment into new appliances, running campaigns, and retrofitting doors on to fridges are a few of the changes they have implemented in order to manage this. However, Chelmsford Star were keen to understand how energy is being used in more detail and needed a better way for managing energy usage company-wide.


With AEMS this company has gained greater visibility into energy usage across their chain of convenience stores.

Visualisation of energy consumption data has helped Chelmsford Star to identify the biggest consuming stores and easily compare the impact this is having on the total consumption. Thanks to the analytics generated by AEMS , they were able to gain deeper insight into the way the stores were operating and producing fresh goods. As a result, the product output of the store was increased and missed sales opportunities avoided, through keeping store managers informed to ensure production was uniform across all of their sites.

“I really like it. It’s simplistic and I know it will be easy for the store managers to use”

The monthly trend data allowed the management team to identify 10 days across three stores where product output was not as expected. Highlighting these days to the Co-op has helped them to gain insight into their business operations and improve productivity.
