The Commission’s Decision regarding the AESO’s Bulk and Regional Transmission Rate Design

In Proceeding 26911, the Alberta Utilities Commission (the “Commission”) issues its decision regarding the proposed regional and bulk transmission rate design of the Alberta Electric System Operator (“AESO”). Alberta’s current regional and bulk transmission rate design recovers transmission costs through energy and coincident peak (“CP”) demand billing determinants. However, most intervenors agree that the associated CP charge overstates the cost of using the grid at peak times, allowing some customers to lower their bills by strategically reducing consumption. The AESO proposed a new rate design that lowers the influence of the CP charge and raises the energy charge to alleviate this issue.

AESO’s Bulk and Regional Rate Design and Modernized DOS Proposal, Oral Hearing

In Proceeding 26911 the Alberta Electric System Operator (“AESO”) and several intervenors cross-examine each other’s evidence for and against the various bulk and regional rate design proposals before the Alberta Utilities Commission (the “Commission”).

Background

Readers may remember our previous article describing the AESO’s rebuttal evidence for their bulk and regional rate design and modernized demand opportunity service application. The current rate design collects transmission costs through a mix of energy and peak demand billing determinants where a monthly coincident peak charge (“12-CP”) recovers two thirds of demand costs.

Bill 22, the Electricity Statutes Amendment Act, Passes First Reading

The Alberta Legislature introduced Bill 22, the Electricity Statutes (Modernizing Alberta’s Electricity Grid) Amendment Act on April 27, 2022. The acceptance of this bill would make several amendments to the Alberta Utility Commission Act (“AUC Act”), the Electric Utilities Act (“EU Act”), and the Hydro and Electric Energy Act (“HEE Act”) to enable energy storage, encourage more self-supply with export, expand the responsibilities of the Minister of Energy (“the Minister”) and begin winding down the Balancing Pool by redistributing its responsibilities.[1]
