Constellation Cold Stores Dublin
Constellation Cold Storage, a leading provider of temperature-controlled storage and logistics services, partnered with Verde Energy Group to install a 1 MWp solar PV system at their facility in Jamestown Business Park, Dublin. With refrigeration requiring substantial electricity throughout the year, the installation provides a sustainable solution to reduce energy costs, lower carbon emissions, and improve long-term energy efficiency.
Why Verde was hired.
Operating in an energy-intensive industry, Constellation Cold Storage required a solution that could significantly reduce electricity costs while maintaining the reliability essential to their operations. Verde Energy Group was selected to design and deliver a large-scale solar PV system tailored to the site's substantial energy demand. By maximising on-site renewable generation, the project allows Constellation to reduce its dependence on grid electricity while making meaningful progress towards its sustainability objectives.
The challenge.
Delivering a 1 MWp solar PV installation across two buildings at an operational cold storage facility required careful planning and coordination. With temperature-controlled storage relying on a continuous electricity supply, ensuring minimal disruption to daily operations was a key consideration. The scale of the installation also required careful system design, roof assessments, and electrical integration to maximise generation while maintaining site safety and operational efficiency.


The outcomes.
The completed 1 MWp solar PV system is expected to reduce Constellation Cold Storage's annual grid electricity imports by an estimate 892,861 kWh, delivering substantial savings on energy costs. The installation provides 23.7% energy self-sufficiency, significantly reducing reliance on grid electricity and exposure to fluctuating energy prices. With a projected payback period of just 4.2 years, the system delivers a strong financial return alongside substantial environmental benefits, avoiding an estimated 227,680 kg of CO₂ emissions annually. This investment demonstrates how large-scale solar PV can provide long-term financial and environmental value for energy-intensive businesses.
