In 2021, five stores were selected to receive refrigeration upgrades. As a result of the energy savings achieved in 2021, Tesco continued their decarbonisation journey by carrying out energy upgrade projects in an  additional forty one stores in 2022. The energy upgrade measures implemented across these stores consisted of refrigeration case upgrades, external co2 pack upgrades, the installation of heat pumps and refrigeration cabinet doors, supported further by the installation of roof mounted solar PV to generate renewable energy.  Overcoming one of the project’s main challenges and mitigating operational risk to Tesco Ireland was achieved by the detailed project management process adopted by ESB Smart Energy Services. This entailed constant communication and strategic planning with Tesco’s key stakeholders and store managers, technical design and equipment review, management and coordination of specialist sub contractors, including all health and safety requirements.
