Generation Interconnection Study

Generation Interconnection Study

Location: Alberta, Canada

Client: Alberta Electric System Operator

Completion Date: 2010

The southern portion of the Alberta Interconnected Electric System (AIES) has the topography perfect for wind generation. A large number of future wind generation interconnections are planned in the south region to take advantage of the windy conditions. Burns & McDonnell assessed the generator interconnections to the AIES to determine system impacts and reliability in the area.

Steady-state analysis

Every generator interconnection request to the AIES has to go through the Alberta Electric System Operator (AESO) study process comprising of several stages. The first study stage is the interconnection proposal stage, when steady-state load flow studies are performed. Burns & McDonnell performed steady-state load flow analysis on existing systems and compared results with post-generator systems to identify potential system deficiencies caused by the new generator.

Results of the studies varied depending on the location of interconnection, but the general conclusion was if approximately 2,700 MW of new generation is seeking interconnection in the next 10 years, the existing system will not be able to accommodate the new generation. New infrastructure will be required to move the additional power to load centers

  • Wind farm interconnections ranged in size from 25 MW to 350 MW
  • 2,700 MW wind generation expected in 10 years
  • More than 7,500 MW of generation requests in queue
