What Is Cogeneration? Six Good Reasons to Choose CHP

Posted by Minesh Patel on 06-May-2014 10:00:00

Here are six reasons why cogeneration is an efficient way to power your organisation.

What is Cogeneration?

Cogeneration, also known as Combined Heat and Power, integrates the production of heat and power into a single, highly efficient process.

Watch the animation now: What is Combined Heat & Power?

During cogeneration, heat used in the generation of power is captured instead of floating away into the atmosphere. Once captured, heat from CHP systems can be used to meet energy demand for a variety of facilities, from industrial factories to government buildings to hospitals and leisure centres.

Cogeneration can slash one of your biggest fixed costs

Spending less on energy is one of the most effective ways to lower expenses.

Organisations using CHP can save between 15 and 40% of their electricity costs over power sourced from the grid and heat generated by on-site boilers.

For example:

Cogeneration can make you friends with Mother Nature

Cogeneration can make your supply more secure

By enabling you to generate power independently, CHP helps you meet your energy demands and reduces your dependency on the grid. It can also help you to balance your energy demands and help you to avoid penalty payments for exceeding maximum agreed supply levels.

CHP systems can even be configured to continue operating in the event of a grid blackout.

Cogeneration will increase the resilience of your heating system

Buildings and Manufacturing Plants use boilers to provide hot water or steam for many different uses, from simple space heating in winter to complex process heating needs such as sterilisation. Installing a CHP plant will increase your capacity to generate heat and reduce your dependence on boilers. A CHP plant may even enable you to switch off your boiler plant altogether at certain times

Cogeneration increases primary fuel efficiency

On average the UK power system is about 35 to 40% efficient in the conversion of primary energy such as coal and gas into electrical energy delivered to our homes. Compare this with Cogeneration which converts 75% to 80% of fuel inputs, up to 90% in the most efficient plants, into useful energy.

Cogeneration is a dispatchable form of energy generation located at its point of use. That means you can choose when it will operate and turn it up or down, as required, without wasting energy in the distribution and transportation of electricity. Renewable forms of energy such as wind are non-dispatchable and are typically located remotely and, therefore. contribute to losses on the transmission and distribution network .

Cogeneration can be funded in part through government schemes

You can be paid to save energy. The UK government offers several incentives to companies that install CHPs, including:

  • EU Emissions Trading Scheme.
  • CRC Energy Efficiency Scheme.
  • Renewable Obligation Certificates (ROCs).
  • Enhanced Capital Allowances.
  • Renewable Heat Incentive (RHI).
  • Climate Change Levy (CCL) exemption.
