AltaLink, Enel seek approvals for 115-MW Alberta wind project

AltaLink Management Ltd. applied June 12 at the Alberta Utilities Commission for the grid changes needed to connect a new, 115-MW wind project to the grid.

AltaLink is seeking a permit to alter and a license to operate the existing Castle Rock Ridge (CRR) 205S Switching Station.

On Jan. 31, Enel Alberta Wind Inc. separately applied with the commission for a transmission interconnection to the Alberta Interconnected Electric System (AIES) to provide wind-generated power through the proposed Riverview substation. The proposed project is located near the town of Pincher Creek, Alberta.

Construction of the interconnect project is scheduled to commence in July 2014 in order to meet the in-service date of Oct. 31, 2014.

The interconnect project is needed to interconnect Enel’s proposed Riverview Wind Power Facility to the AIES. The Enel project is a large generation project at 115 MW. If the connection is not in-service by Oct. 31, 2014, Enel’s commercial operation date may be delayed, AltaLink told the commission. This will affect the financing in terms of commitments to equity and debt investors and impact the cost of construction financing.

Enel said in its Jan. 31 application that the Riverview project is to be located to the east of the existing Enel Castle Rock Ridge Wind Power Plant. Enel is proposing to install 50 Siemens 2.3-101 turbines to achieve the nameplate capacity of 115 MW targeted for the Riverview project.

Enel Alberta Wind is a division of Enel Green Power North America Inc. and part of the Enel Group of companies. Enel is an owner and operator of renewable energy plants in Canada with projects operating and under development in three Canadian provinces.

Electricity generated at the Riverview Wind Power Plant will be gathered by an underground collector system and routed to a new project-specific substation called the Riverview Substation, to be located adjacent to, but separate from the existing Enel Castle Rock Ridge project-owned substation. The Riverview project will utilize the existing transmission line previously constructed to join the AltaLink Castle Rock Ridge 205S Substation to the Goose Lake Substation. No new transmission will be needed for this project.

In the spring of 2012, Enel said it decided to merge the formerly separate Riverview Wind Power Plant and Highway 785 Wind Power Plant into a single project that is now only referred to as the Riverview Wind Power Plant.
