A guide to on-site generation technologies

Learn about cogeneration and other technologies that complement each other and generate energy on-site for your business.

When buying electricity from a supplier, approximately 20% of the cost is to pay for transportation from a large power plant, through the networks, to your connection. By generating your own energy and reducing consumption on-site, these costs can be avoided and any surplus can be sold for extra revenue. Generating your own energy also gives you control to lower your carbon emissions and increase the reliability of your electricity supply.

On-site technologies

We consider all technologies available on the market and design a solution that is best suited to your needs and the existing site infrastructure. Our solution will combine the benefits of a range of technologies, including:

Onsite generation technologies

Congeneration (Combined Heat and Power): Reduce energy costs and carbon emissions in production facilities where there are combined heat, power and cooling requirements.

Solar and Storage: Reduce your reliance on the grid and save on your electricity supply and demand spend with solar power generation plus storage.

Rudox Power Generation: Improve your resilience with back-up power generation on site to support your business and your energy strategy.

Continuous cogeneration power in times of need

Centrica Business Solutions joined with Controlled Air, Inc.; O,R&L Construction; Power Island Energy; and several other companies to deliver a cogeneration system featuring chilled and thermal water loops, controls system and underground piping for a microgrid to power key municipal buildings for the city.

The design build portion of the project was managed by O,R&L Construction, specialists in commercial building services.

The microgrid includes three Combined Heat and Power (CHP) units, a stand-by power generator set provided by Centrica Business Solutions and an electrical power network designed to provide continuous power during grid failure. The project was part of a municipal pilot program launched through the State Department of Energy and Environmental Protection (CT DEEP) in 2013.

Right result

The microgrid provides power to key municipal buildings, and utilizes the engine heat loss to supply heating and cooling to critical facilities, such as City Hall, the Police Headquarters and the Golden Hill Senior Center.

The team has estimated annual savings of approximately 85,554 MMBtu in energy, all while meeting several budget and city needs. The microgrid was built with 100% redundancy at no cost to the city, with the potential for reducing environmental impact and long-term energy costs.
