Reducing Fuel Costs with Hybrid Solar Systems
Voltalia, a renowned player in renewable energy, sought innovative ways to reduce operational costs and enhance sustainability on one of its projects. A large-scale solar farm, which powers Canary Wharf in London, presented an opportunity to incorporate solar energy into its existing temporary power systems.
Seeking to optimise their energy usage and lower fuel costs, Voltalia approached Power Electrics for a specialist solution. This case study delves into the challenges faced and the bespoke solution provided by Power Electrics.
The Challenge
Voltalia was already utilising Power Electrics' generator and hybrid systems on-site but desired to further reduce fuel expenses. Having made significant investments in their solar farm, the aim was to harness this renewable energy and store it in Battery Energy Storage (BES) units.
The primary challenge was integrating the direct current (DC) charge from the solar panels with Power Electrics' 45/90 Hybrid units, an operation that would typically be outside the standard operational capabilities.
The Solution
South Coast Sales Engineer Steve Richardson understood the unique requirements and collaborated with Rob Mason, Project & Solution Manager, to devise a tailored solution for the customer. Power Electrics procured and installed a specialised adapter that enabled the 45/90 BES units to accept a DC charge from the solar panel arrays.
Rob Mason spearheaded the adaptation process, meticulously fitting and testing the adapter to ensure seamless integration and optimal performance. The result was a successful implementation, showcasing Power Electrics' commitment to pioneering solutions and supporting clients in their sustainability goals. The system reduced generator run-time and fuel usage by 50% and saved over 4500kg in CO2.
Through this collaboration, Voltalia not only achieved its goal of reducing fuel costs but also set a precedent for future renewable energy integrations in hybrid power systems.
It was an interesting challenge to figure out how to harness the power from these solar panels, and it was great working with Voltalia on a successful solution.
The Results
(May 2024) Hybrid System Savings:
Reduction in run-hours: 51%
Reduction in fuel consumed: 51%
CO2 savings: 4550.15kg
Generator runtime: 360:59hrs
Following the success of this project, Power Electrics is currently working with Voltalia to install another 135kVA/180kWh containerised battery energy storage unit, aimed at offering further emissions savings.
