RHI:
Independent Report on Metering Arrangements
The Independent
Report on Metering Arrangements (‘the Report’) is intended to verify to Ofgem that an installation seeking accreditation
to the Renewable Heat Incentive (RHI) has metering arrangements in place which meet the RHI eligibility requirements, in accordance
with the RHI Regulations. The Report will cover the installation’s metering arrangements for RHI
purposes, including:
- whether meters and sensors are correctly positioned;
- whether meters and sensors are installed in accordance with the manufacturer's instructions;
- whether the schematic diagram is an accurate representation of the installation and the heating system of
which it forms part.
Circumstances
under which the Report will be needed:
In accordance with Schedule 1 of the Regulations, this Report will be requested by Ofgem as part of the application
for RHI accreditation, where an installation:
- has a capacity of 1MWth or above, or
- is classed as a complex installation for RHI
metering purposes.
Generally all installations that fall into the above categories will need to provide a completed Report as part of the
accreditation process.A Report will also be required in the following
scenarios:
- where additional RHI capacity takes an accredited
installation's capacity over 1MWth, or
- where additional RHI capacity takes an accredited
installation's capacity over 45kWth and the installation is considered complex for RHI metering purposes,
- or where a change is made to the installation/heating system that results in an RHI-accredited installation
moving from a simple to complex classification for RHI metering purposes.

Competency Criteria for 'Competent Person'
According to the Regulations, only a can complete
this Report. A 'Competent Person' means a person that meets of
the following criteria:
1. An experienced and suitably qualified engineer
(at least HND or equivalent in an engineering discipline from a recognised academic institution);
2. Has demonstrable
experience and expertise in flow measurement and heat/steam measurement systems demonstrated by training and development
records;
3. Has a relevant background (involved in energy, utilities, building
services, heating system design, heating system operation & maintenance);
4. Covered
by Professional Indemnity Insurance (through employer or directly);
5. Is unbiased and impartial.
Details of installation
- The plant number/identifier is the tag that will enable the plant to be
identified on the schematic diagram. We will uniqueally identify the primary plant and apply a site identifier.
- The technology type
must be one of the following:
- solid biomass (please indicate whether it is a CHP plant)
- municipal solid waste (please indicate
whether it is a CHP plant)
- biogas
(please indicate whether it is a CHP plant)
- geothermal
(please indicate whether it is a CHP plant)
- ground
source heat pump (please indicate if this will be used to generate cooling as well as heating)
- water source heat pump (please indicate if this will be
used to generate cooling as well as heating)
- solar
thermal.
- The total installed peak heat
output capacity of each plant should be assessed and clearly identified on schematic diagram and alll other
information to be submitted to Ofgem.
- Please
note 'word of warning' that biogas and solar thermal installations are not eligible for the RHI if they
have a total installed peak heat output capacity above 200kWth.
- Heat
use We will provide a detailed description of the building(s) in which the heat is used for eligible purposes, stating
clearly the number of buildings in which heat is used for eligible purposes for Ofgem.
- Heat
transfer medium We will detail the heat transfer medium used in the heating system of which the installation
forms part. Only liquids (such as water, water-ethylene glycol mix, oil) or steam are eligible heat transfer media for the
RHI for eligible purposes for Ofgem. Please note: Other
media, such as hot air, are not eligible.
Simple/complex
metering arrangements We will detail whether the installation is classed as ‘simple’ or ‘complex’
for RHI-metering purposesfor eligible purposes for Ofgem.
'The Way Forward'
We would be delighted
to guide and support you through the process.
