AECO HUB™

The AECO Hub™, AECO's commercial natural gas storage business in Alberta, Canada, is comprised of two gas storage facilities:

• Suffield (South-eastern Alberta)
• Countess (South-central Alberta)

Although the two AECO facilities are geographically dispersed across Alberta, the toll design of the Nova Gas Transmission Limited pipeline system means that they are all, commercially, at the same point.

Total gas storage and deliverability capacity of the AECO Hub:

Working Gas Capacity	125 BCF
Peak Withdrawal Rate	3.05 BCF per day
Peak Injection Rate	2.40 BCF per day

Alberta is a tremendous oil and gas basin. The AECO Hub has converted some of the best of those reservoirs into some of the highest quality, lowest cost storage facilities on the continent. Located in the midst of high liquidity and accessibility to most market regions, the AECO Hub is the best storage bargain in North America.
