St Mary’s Catholic High School
About the client
St Mary’s is an 11-18 Catholic Voluntary Academy serving North East Derbyshire. A thriving, highly successful and over-subscribed school with a long and well established reputation. With an outstanding record of academic achievements and examination results consistently well above the national average.
Drivers for the project
The school has over 1200 students and has an energy demand to match, the school also operates before and after school clubs which sees a requirement for electricity from 7am-7pm.
As with many schools the budgets were tight and the need to reduce the electricity bills was quickly becoming very real.
The system will produce enough electricity (240,464 kWh per annum) to power around 65 residential homes per year or power 109 electric cars. After 25 years in operation the project is predicted to have saved 472.4 tonnes of CO2e, an equivalent of 2,444,640 fossil fuelled car miles, 310 fossil fuelled cars off the road and 1890 pine trees planted.
The school sits across a sprawling site and nearly all the roofs were required to reach the generation targets, this became a challenge due to the amount of scaffolding an access equipment that would impact and reduce the playground area.
Installation across the school was completed with a phased approach, ever respectful of such a busy and potentially dangerous site, Custom Solar completed the school in manageable sections meaning that the school were never without their much needed space.
The initial programme was to complete the installation within three weeks and we successfully delivered a fully commissioned system following a client handover within the contracted period and importantly ahead of the Feed In-Tariff deadline.
The funded energy model adopted by the school has seen electrical demand from the grid decrease and the savings against energy increase. The school has also been provided with key stage learning tool for all ages of students to learn about solar and other renewable energies.
