Generator Output and Capability

The Hourly Generator Energy Output and Capability Report presents the energy output and capability for generating facilities in the IESO-administered energy market with a maximum output capability of 20 MW or more. For variable generation only, forecast values are published instead of capability, as this provides a more accurate view of how much energy these units could be expected to produce.

Hourly Ontario Energy Price (HOEP)

In the IESO-administered market, the Hourly Ontario Energy Price (HOEP) is charged to local distribution companies (LDCs), other non-dispatchable loads and paid to self-scheduling generators. Businesses that use more than 250,000 kWh a year pay the hourly price. The HOEP is also the basis for regulated rates charged to residential and small business customers. The HOEP values are reported as $/MWh.

SBG Forecast Report

Surplus Baseload Generation (SBG) occurs when electricity production from baseload facilities (such as nuclear, hydro and wind) is greater than Ontario demand. These forecasts consider near-term forecasts for hydro-electric and other baseload generation as well as weather conditions which impact demand. The IESO endeavours to provide as much information in advance so that market participants are aware of potential SBG conditions and can plan their businesses and respond appropriately.

SBG forecasts do not include exports. Forecasted exports is, however, also included to provide an indication of the amount of SBG that may be alleviated through exports.

Minimum Generation Alerts: When conditions warrant, the IESO will announce a Minimum Generation Alert or Event through an advisory notice and in the SBG Forecasts.

For longer-term forecasts, participants should refer to the current 18-month Outlook which provides an assessment of forecast weekly minimum demands and expected baseload generation for the next year and a half. Participants are advised to refer to the difference between the Weekly Minimum Demand MW and the Baseload Generation MW columns as an indicator of Ontario's exposure to future Surplus Baseload Generation risk.

Variable Generation Forecast

The Variable Generation Forecast Summary reports shows forecasts of solar and wind generation connected to the grid and embedded within distribution systems for the next 48 hours. Currently all grid-connected as well as embedded generation facilities with installed capacity of 5 MW or greater are required to register with the centralized forecasting service. The reports include total provincial forecasts and in areas where there are at least three facilities in operation, zonal forecasts are also included.

Price Bias Adjustment Factors

The intertie failure charge calculation includes the difference between the pre-dispatch and real-time Ontario price during the hour of the failure. This difference is adjusted by a price bias adjustment factor, which compensates for the different methods used to calculate the pre-dispatch and real-time Ontario prices. These price bias adjustment factors are to be used in the settlement charge calculation for the real-time import and export failure charge, as well as the day-ahead linked wheel failure charge.
