There is a legal requirement to reduce carbon dioxide emissions. Increasing the proportion of heat produced from renewable energy will achieve this.
However one of the barriers to wide-spread deployment is the high initial cost of the plant. The government introduced the Renewable Heat Incentive (RHI) in 2009 to offset this cost, but has recently closed the scheme.  Accredited applicants receive payments for twenty years following a successful application.

The application process involves the initial submission and may involve a heat loss calculation and an independent metering report. Following this, there can be a period of clarification requests from Ofgem which usually require detailed technical answers. TSI Scotland are qualified to manage the entire process for you.

The following technologies are covered by the RHI:

  • Biomass boilers
  • Biomass CHP
  • Solar hot water panels
  • Ground source heat pumps
  • Air source heat pumps
  • Biogas

Where TSI Scotland can help

Although the RHI has now closed to new applicants, there is still a considerable amount of outstanding clarification to be managed.  This is likely to last for at least another year on a number of projects.  If the installation has multiple buildings or external pipework, it is likely that Ofgem will request an Independent Report on Metering Arrangements (IRMA) supplied by an independent inspector.

Once the plant has been RHI-accredited, there is an on-going need to supply regular meter readings to Ofgem.  This can be an involved process on some sites and TSI Scotland are often asked to manage this interface for the customer.

The IRMA metering report

Metering reports must be carried out by an independent assessor who meets the following criteria:

  • Experienced and suitably qualified
  • Has experience and expertise in flow measurement
  • Has a background in utilities services
  • Is unbiased and impartial
