IESO to introduce new dispatch tool for grid-connected wind resources

Toronto, ON, Canada — (METERING.COM) — September 5, 2013 – Ontario’s Independent Electricity System Operator (IESO) is to introduce a new dispatch tool for all grid-connected wind resources with effect from September 11.

The dispatch will apply to 1,725 MW of existing transmission-connected wind resources as well as an estimated 3,000 MW of transmission-connected wind and 280 MW of transmission- connected solar expected to come into service over the next 18 months. Distribution-based wind and solar facilities, forecast to total almost 2,400 MW during this period, will not be subject to grid dispatch, but the output from those facilities will now be visible to the IESO’s system operators.

The enhancements also include state-of-art wind forecasting to assist in planning and executing daily operations.

“The IESO is constantly looking for ways to improve the efficient operation of the province’s electricity market, while promoting continued reliable supply,” said Bruce Campbell, president and chief executive officer of the IESO. “The dispatch of variable generation – wind and soon solar – will help reliably and efficiently integrate the growing fleet of variable generators into our system.”
This new capability adds an important lever to the reliable operation of Ontario’s bulk power system. It gives operators another source of flexibility to meet ramping requirements as demand for electricity increases and decreases over the day, and to manage surplus baseload generation. Within the availability of wind, wind turbines can be highly flexible, increasing and decreasing output very quickly in response to system needs.
