AESO Core Business Functions
THE POWER OF POSSIBILITY
Who Is the AESO?
• Statutory organization: integration of previous
Power Pool and Transmission Administrator
functions
• Not-for-profit
• Revenue generated from trading charge and
transmission tariff
• Hold no assets
• Impartial - no affiliation with industry players
• Regulated by the Energy and Utilities Board
• Governed by board of directors appointed by the
Minister of Energy

Transmission Planning Process
THE POWER OF POSSIBILITY
Transmission Planning - The
Process
• Determine the inputs.
• Identify the anticipated problems.
• Develop the alternatives.
• Analyse the alternatives.
• Choose the preferred solution.
• Initiate the project(s).
THE POWER OF POSSIBILITY
Transmission Planning - The Inputs
• Load - forecast, location, timing, peak vs. off-peak
• Generation - size, location, timing, merit order
• Existing system - capacity, equipment ratings,
operating constraints
• Planning criteria - bulk system, subtransmission,
load supply stations
• Externalities - siting and routing considerations,
planning horizons for other stakeholders, other
jurisdictions

Transmission Planning - Project
Initiation

•
•
•
•
•
AESO determines need for system expansion or upgrade.
AESO prepares Need Application and files with Energy and
Utilities Board (EUB).
EUB considers application and makes decision.
Following receipt of EUB approval AESO “procures” project
from a transmission facility owner (TFO).
TFO prepares and files Facility Application with EUB.
EUB considers application and makes decision.
Following receipt of EUB approval TFO proceeds with
construction of project.

AESO Transmission Strategy
Objectives
•
To define a transmission system development strategy that
will enable the timely approval and construction of
transmission facilities so as to:
•
•
•
Provide adequate transmission facilities that will meet
defined reliably and performance criteria and provide
efficient service
Facilitate the development of new generation in the
system
Facilitate the competitive wholesale electricity market so
as to allow market forces to minimize the overall
delivered wholesale cost of electricity to consumers
• Strategy Deliverable:
The “Conceptual Plan”
THE POWER OF POSSIBILITY
The Conceptual Plan
•
Objectives:
•
20 year outlook for system development
•
•
•
•
•
•
primary focus on 500 kV development
Better understanding of the implications of alternative
generation and export scenarios on the development of the
transmission system
Preliminary evaluation of the impact on the overall costs of
generation and transmission costs of the alternative generation
and export scenarios
3 generation scenarios - Ft. McMurray, Edmonton area,
southern Alberta area
3 export scenarios - 0, 1000 and 2000 MW
2 load forecast scenarios - expected, high
