Case Study: Cutting costs and carbon – A large-scale Commercial Solar & Battery Installation

Introduction

In an era of rising energy costs and increasing pressure to meet sustainability targets, the leading UK independent access firm, GT Access sought a long-term solution to reduce its operational expenses and environmental impact. With a large facility consuming significant amounts of electricity, the business identified Solar PV and Battery Storage as a strategic investment. Working with M J Wallace limited, the company commissioned the design and installation of a high-capacity Commercial Solar energy system, paired with advanced battery storage.

The goal: to maximise on-site energy generation, cut reliance on the grid during peak hours, and lock in long term savings.

Challenge

The business faced several key challenges:

Escalating energy costs, with unpredictable annual increases impacting profitability.
A high, consistent daytime electricity demand due to continuous operations.
A need to demonstrate meaningful carbon reduction as part of corporate sustainability goals and upcoming net zero targets.

Solution

M J Wallace limited delivered a tailored energy solution that included:

A 173kwp solar pv system mounted across available roof space, optimised for year-round generation.
A 384kwh battery storage system, configured to store excess daytime generation for use during peak tariff periods and overnight loads.
A smart energy management system to monitor performance and optimise usage patterns.
End-to-end project management including design, installation, dno liaison, and post-install support.

Results

Within the first year, the system delivered:

An estimated £40,000 in annual energy savings.
Over 100,000 kwh of clean electricity generated on-site.
A reduction in grid electricity usage during business hours, regularly showing 100% self consumption estimated annual co₂ savings of over 20 tonnes.
ROI projected at under 5 years, with 25+ years of continued benefit.
