Your unit rate calculation
The unit rate charge (in pence per kilowatt-hour) for a given half-hour period is:
min(2.2 x W + P, 33.33)
where:
So today 7-7:30 has a unit rate of 32.34, then dropping to 16.84
6:30-7 is 34.65
So either wholesale price is double for that 30 min or they added another 30 min for their +12p "peak".
The unit rate charge (in pence per kilowatt-hour) for a given half-hour period is:
min(2.2 x W + P, 33.33)
where:
- 2.2 is a coefficient that includes our distribution costs
- W is the wholesale cost of electricity for that period (in pence per kilowatt-hour)
- P has value 12.00 between 4pm and 7pm but is zero otherwise.
- 33.33 is chosen to ensure the price is capped at 35p/kWh once VAT is added.
So today 7-7:30 has a unit rate of 32.34, then dropping to 16.84
6:30-7 is 34.65
So either wholesale price is double for that 30 min or they added another 30 min for their +12p "peak".
