Micro CHP / Micro Cogeneration

CHP

Cogeneration (CHP) is a well-proven technology, recognised worldwide as a cleaner alternative to traditional centralised generation. Its long-term future in the global energy markets is secured by CHP’s ability to provide a multitude of financial, operational, environmental and legislative benefits from a single unit of fuel.

Financial Benefits: 

  • Reduced primary energy costs
  • Zero capital outlay options available
  • Stabilised electricity costs over a fixed period
  • Reduced investment surrounding plant e.g. boilers
  • Eligible for Enhanced Capital Allowances
  • Potential ROCs eligibility (Biogas, Liquid Biofuel)
  • Potential benefits from Renewable Heat Incentives
  • Sufficient savings to fund energy efficient measures

Operational Benefits:

  • Reduced base load electricity supply
  • Additional security of supply
  • Increased diversity on heating and hot water
  • Steam raising capabilities on larger units
  • Choice of multiple fuels
  • Cooling provision using absorption chillers

Environmental Benefits:

  • Reduced primary energy use
  • Reduced CO2 emissions
  • Helps with carbon legislation compliance
  • Reduced transmission losses from the grid
  • Lower SOx emissions with the use of natural gas as a fuel

Legislative Benefits:

  • Helps with Part L compliance
  • Helps meet the CRC Energy Efficiency Scheme (CRCEES) targets
  • Helps reduce carbon footprint
  • Avoids Climate Change levy

A compact and efficient solution

Organisations are increasingly looking for environmentally friendly systems to supply their building energy needs. By generating electrical power on-site, losses associated with electrical power transmission are reduced and the waste heat energy produced can be used for heating or cooling. This is micro cogeneration.

Micro cogeneration or combined heat and power (Micro CHP) technology converts natural gas into both electricity and heat in a single process on site. The natural gas fuel is more beneficial to the environment than other fossil fuels, as the emissions, such as CO2, NOx and SOx are comparatively smaller. Micro cogeneration systems offer a higher overall efficiency than typical conventional electrical power generation, achieving reduced energy consumption, reduced CO2 emissions, and reduced energy costs.

While the typical efficiency of central generation is around 35%, micro CHP technology is more than twice as efficient and can achieve efficiency up to 85%.

ENER-G’s experience in the cogeneration market dates back to the 1980s when we began to design, manufacture, install and maintain cogeneration systems. From smaller systems to large, complex heating solutions, between 10kWe and 5MWe we deliver the best fit to all requirements. The micro series are the most recent addition to our product portfolio, as a result of a technology partnership with Yanmar, a leading Japanese manufacturer. This allows us to offer this both environmentally and economically beneficial energy technology to small and micro applications, in the 10-25kW range.

The compact Japanese design can benefit the residential, health, retail, leisure, commercial, industrial and public sectors

Micro Combined Heat and Power is highly energy efficient and as well as supplying a business with power and heat, it can deliver a number of positive financial and environmental benefits.

Operational benefits

  • High availability
  • Ease of use by automatic operation
  • Minimal service requirement with long service intervals (10,000 hours)
  • Acts as a backup supply for non-essential heat and power
  • Piece of mind with optional remote monitoring

Environmental benefits

  • Reduced primary energy use
  • Reduced building carbon footprint (lower CO2 emissions)
  • Reduced transmission losses
  • Low noise design:
    ENER·G 10Y: 56 dBA at 1m
    ENER·G 25Y: 64 dBA at 1m
  • Low NOx exhaust

Financial benefits

  • Reduced energy cost by up to 40%
  • Reduced life cycle cost by long service intervals
  • Can reduce the cost impact of the Carbon Reduction Commitment (CRC)
  • Good quality CHP can attract enhanced capital allowances for eligible organisations (ECA’s)

Legislative benefits UK

  • Helps in meeting Carbon Reduction Commitment (CRC) targets, with the useful heat from micro CHP being zero rated.
  • Helps to meet carbon footprint targets for new and redeveloped buildings under the Part L of the Building Regulations
  • Under the 2008 Energy Act micro CHP up to 50kWe qualifies for the Feed-in Tariff (FIT) system for renewable electricity technologies
