RPP - Regulated Price Plan
The RPP stands for Regulated Price Plan. The Ontario Energy Board (OEB) adjusts the rates twice a year to reflect the variance between the amount customers paid for power and the cost of supplying it.
Since the OEB sets RPP prices based on a forecast of supply cost over a period of time, there is likely to be a difference, or variance, between what RPP customers pay and the actual cost of supplying power, which is accumulated in a variance account.**
How does this relate to the EnergyOne program? With HOEP you are no longer subject to the RPP and buy your power based on wholesale energy prices.
HOEP
Why is HOEP important to me?
HOEP refers to the Hourly Ontario Energy Price. HOEP is the hourly spot price for electricity supply that is dispatched by the IESO. The IESO, Independent Electricity System Operator, manages Ontario’s electricity system and operates the wholesale electricity market. The IESO publishes HOEP rates and determines market prices. It forecasts the demand for electricity and ensures that there are available supplies to meet that demand.
More than half of all electricity consumed by this province is paid for at wholesale rates. Most low-volume consumers, however, pay regulated rates that are revised every six months by the Ontario Energy Board, based on market and contract prices paid to generators (the Regulated Price Plan - RPP).*
With EnergyOne you can take advantage of the weighted average Hourly Ontario Energy Pricing.
