After an introduction to the CRC Energy Efficiency Scheme, this post should give you an outline of the different types of energy supplies covered by the CRC scheme.
There are 29 energy sources covered in the CRC scheme and it is important that organisations keep a careful record of any consumption from these sources.
In the CRC, energy sources are split into core energy supplies and residual energy supplies. 27 of the 29 energy sources are residual supplies; these must be counted, but not necessarily always declared:
CRC Electricity Meters:
Electricity and Gas in the CRC can be either core or residual supplies, depending on the type of supply and meter associated with that supply.
A core electricity supply is a supply measured by a meter which is one of the following:
- settled half hourly meter
- non-settled half hourly meter
- a non-domestic meter
- a dynamic supply
You are able to distinguish the type of supply by identifying the meter profile type; half hourly meters (HHM) are profile "00":
AMR meters can be read remotely and capture data on at least a half-hourly basis, while non-domestic meters are generally profile types 05-08 (05, 06, 07 and 08).
Most other types of electricity supplies are classed as residual energy supplies:
CRC Gas Meters:
In terms of Gas, there are three types of supply that are considered core gas supplies:
- Daily Read Meter
- An hourly meter (remotely read AMR meter)
- A large gas point meter
A large gas point meter is a non-remotely read (AMR or daily read) meter with a supply greater than 73,200 kWh per annum. Most other meters will be non-daily read ≤ 73,200 kWh per annum; these meters are classed as residual supplies.
Here's an example of these meters available in our ECM software:
As you can see from the CRC dashboard within ECM, all relevant emissions are routed to either core or residual energy supply. The percentage gives you an easy indication of how much carbon you have to declare in your CRC footprint or annual report:
