We’re building a system for a major international utility, and some interesting snippets have popped up about Gas, Power and Carbon Emission trades:
- Carbon trades are sold by the thousands of tonnes. This tonnage represents the EU allowance of carbon emissions. ”Delivery” (or rather the ability to use the emission allowance) is after a set date. Price is in Euros per tonne.
- Gas trades are sold by thousands of Therm. Priced in pence per Therm. Trade Quantity is Therm’s per day – so if the trade is for delivery over more than one day, the Total Trade Volume is Therm’s per day * Total Delivery Days. Gas days start and end at 06:00
- Power trades are sold by Megawatt Hours (MWh). Priced in pounds per Megawatt Hour. In the UK, any single product is delivered over one or more power blocks. Each block is 4 hours long. As a result, if a trade is for 100 Megawatt Hours on a single day over 2 blocks, then the delivery total for the day is in fact 800 MWh (2 blocks * 4 hours * 100 MWh). Power days start and end at 23:00
