Key Facts

Roadstone is committed to reducing absolute gross Scope 1 and Scope 2 GHG emissions by 42% by 2030 from a 2021 base year, an important milestone of an overall strategy towards achieving the ambition to be net-zero by 2050. Sustainable development and the integration of renewable technologies into Roadstone infrastructure is integral to our commitment to decarbonisation.

The Challenge

Roadstone locations are strategically positioned nationwide with a diverse product range and customer requirements. The processes at each location operate at varying energy intensity levels and have specific energy demand profiles. Maximizing the energy output associated with the renewables for use within the site boundary requires consideration of a wide range of factors and extensive research. 

The Solution

Roadstone implemented a solar farm in Duleek as a pilot project. This gave an opportunity to evaluate the location by maximising the output of the solar panels. 

The project allowed the development of autonomous data reporting, and assessing what factors to considered in evaluating future larger scale projects at further locations.

The Result

The recent annualized Renewable Energy output from the Solar Panels was 67,391kWh of which 55,100kWh was consumed on site. 

This means that the bleed from the generated solar was maintained at less than 18%. 

Further enhancements were subsequently made by the electrical management team to reduce the bleed rate and ensure as much as possible of the renewable energy is consumed on-site.
