Cogeneration, also called Combined Heat and Power (CHP), is the simultaneous generation of both electricity and useful heat in a single process. By capturing the waste heat, CHP increases fuel efficiency by reducing the losses inherent in electricity production. CHP is available in a wide range of sizes for many different applications using a variety of fuels. The recovered heat is typically used as part of industrial processes, hot water, space heating, or cooling.
Recent revisions under SAP10, which establishes the acceptable figures for carbon intensity, have dramatically impacted the advantages of micro-CHP (electrical outputs up to 50 kWe). This has seen the technology shift from carbon positive to now being negated. Local initiatives such as the London Plan, which is seeing widespread adoption across UK cities, and the latest Government drive to address the adoption of sustainable energy within buildings with a focus on electricity and heat pumps has also proven detrimental to CHP, impacting the operational savings. In response Adveco will no longer carry m-CHP in its current portfolio.
Single, non-m-CHP units of 50-100kW+ remain carbon neutral and savings at this scale can be considerable.
Adveco treats its projects as bespoke, and the application design and sales teams can advise on best options and where needed be able to support, through technical partnerships, the supply of CHP units from 20kW up, with full manufacturer grade engineering and warranty support.
In absence of m-CHP in our product portfolio, we will, as a matter of course, default to hybrid gas or electric systems that leverage the high-efficiency advantages of Air Source Heat Pumps (ASHP).
We continue to operate the service contracts on m-CHP units already installed, and our expertise remains available to consultants who still require CHP for their project.
