Facility Upgrade Studies

• Ketchikan

AUTO Vista was selected by Ketchikan Public Utilities in Ketchikan Alaska as the model to perform a series of analyses including benefits assessments of various unit upgrade alternatives, plant expansion alternatives and hydraulic connectivity layouts for the Beaver Falls system. The Beaver Falls system is comprised of three reservoirs and two power plants with an existing installed capacity of 9.4-MW.

Evaluation of the benefits results is on-going and selection of the desired alternative and start of construction is scheduled for late 2006.

• Lower Mattagami

The Lower Mattagami System is comprised of four reservoirs and four power plants with a total capacity of 484-MW.

LT Vista and AUTO Vista were selected as the models to perform detailed analyses of plant expansion alternatives at Little Long, Harmon and Kipling, as well as an analysis of a complete redevelopment of Smoky Falls.

From Hydro Review, Vol. XXV, No. 5, September 2006:
Ontario adds 460 MW to Mattagami
Ontario Power Generation announced it plans to add 460-MW to its Lower Mattagami River hydro system by building a new 250-MW powerhouse and upgrading three other projects. The program includes: a new 250-MW powerhouse to replace 52-MW Smoky Falls station; increasing capacity of the 136-MW Little Long project by adding a 70-MW unit, plus upgrading existing runners; increasing capacity of the 140-MW Harmon project by 96-MW from a runner upgrade and installation of a new 79-MW unit; and increasing capacity of the 158-MW Kipling project by 96-MW from a runner upgrade and installation of a new 78-MW unit.

• Vernon and Comerford Plants

AUTO Vista was selected by TransCanada , Connecticut as the model to perform benefits assessments of various unit upgrade alternatives at the Comerford Station, and plant expansion alternatives for the Vernon Station. Both stations are located on the Connecticut River. The Connecticut River System is comprised of nine reservoirs and six plants. The existing Comerford Station installed capacity is 153-MW from four generating units, and the Vernon Station installed capacity upon completion of the plant expansion project will be 41.6-MW.

Evaluation of the unit upgrade alternatives for the Comerford Station is on-going and selection of the desired alternative and start of construction is scheduled for late 2006. The Vernon plant expansion alternative has been selected and the expansion project is underway.
