Who is the AESO?
Alberta's transmission system, sometimes referred to as the Alberta Interconnected Electric System (AIES),
is planned and operated by the AESO. The transmission system comprises the high-voltage lines, towers
and equipment (generally 69 kV and above) that transmit electricity from generators to lower voltage
systems that distribute electricity to cities, towns, rural areas and large industrial customers.
The AESO's role is to maintain safe, reliable and economic operation of the AIES. The AESO's planning
responsibility includes determining the need for transmission system development and the manner in
which that need is met. The AESO is also mandated to facilitate the interconnection of qualified market
participants to the AIES. The AESO is regulated by the AUC and must apply to the AUC for approval of its
needs identification document (NID).

Spring 2012
How is AltaLink involved?
AltaLink is the transmission facilities owner (TFO) in the Glenwood and Lethbridge planning areas. While the
AESO is responsible for identifying the need for transmission system development, AltaLink is responsible
for detailed siting and routing, constructing, operating and maintaining the associated transmission facilities.
The AESO has directed AltaLink to provide information to stakeholders on this need and to file a facility
proposal application with the AUC which will include a detailed description and location of the proposed
transmission development.
Further Information
The AESO appreciates your views on transmission system development and your comments are
encouraged. The AESO will be hosting the following information session to discuss this change to the
potential development area:
Coaldale
June 21 – 4-8 p.m.
Coaldale Community Centre
1217 – 20 Avenue
If you have any questions or suggestions regarding the proposed changes to the potential development
area, please contact:
