Main results:
- Bridging the gap of a grid delay
- Using sustainable solutions with one of our main rental company partners in the UK – saving 23618 litres of diesel and 76 tonnes of CO2
- Showing how our Energy Management System (EMS) enhances traditional solutions in a hybrid setup with flexible, adaptable options.
Powering your project through grid delays
St. Katherine’s school in Essex is one of the 62 schools built with collapse-prone Raac, or reinforced autoclaved aerated concrete. A temporary solution was needed while the site waited for a bigger grid connection for the construction of the new school to begin.
Sadly, grid connection delays are a growing problem. Many projects are stuck in limbo, waiting years to get connected. This wastes time, money, and slows down the vital projects and infrastructure.
At Greener Power Solutions, we help you bypass these delays. With our batteries and Energy Management Systems we can assess the specific needs of your project, providing the most sustainable and cost-effective solution. Hybrid set-ups are one of the most accessible ways to make construction sites more efficient and sustainable.

Hybrid solutions
We provided a hybrid solution by connecting one of our batteries (alongside our EMS) to a generator. In the case of Katherines School project Wernick was able to use a 200 kVA generator alongside our 422 battery to power the project. The battery calls on the generator when needed to charge it, while the battery is powering the site itself. Both battery and the generator only run when needed, leading not only to quiet nights, but also significant savings in cost and emissions. Together we were able to save 23618 litres of diesel by decreasing generator running time by 1346 hours. .
Both Wernick and Greener Power Solutions are committed to sustainability and, together we were able to save 76 tonnes of CO2 as well as 361 kg of Nox.
Back to School
Greener Power solutions, together with Wernick were able to support getting Katherine’s pupils back into the classroom by powering nine temporary classrooms, using a hybrid set up. The temporary structures offered air conditioning and bigger classrooms, alongside more space for arts and physical activities. With the site now connected to a bigger grid, the construction of the new school structure can finally start.
