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.

AESO 2018 Tariff: Changes affecting Distributed Connected Generators

On September 22, 2019, the Alberta Utilities Commission (the Commission), in Decision 22942-D02-2019, gave its ruling on the 2018 Independent System Operator Tariff application. This decision included approval for the adjusted metering practice proposed by the Alberta Electric System Operator (AESO), as well as changes to the substation fraction allocation method. These two changes are particularly significant to distributed connected generators (DCGs).

AESO 2018 ISO Tariff Application

The Alberta Utilities Commission (AUC) directed the Alberta Electric System Operator (AESO) to suspend the application of Information Document 2018-019T (ID) regarding the determination of Rate STS (supply transmission services), Rate DTS (demand transmission services), and metering levels for distribution system connected generation. The Commission determined that the ID should be tested in the AESO 2018 Independent System Operator (ISO) tariff application proceeding (22942) before requiring parties to implement the change.

AESO Deferral Account and Rider C

On January 30, 2017, the AESO hosted another information session on the 2018 AESO tariff application. The session did not provide much in terms of new information, but the AESO informed stakeholders that they intend to propose changes to the deferral account allocation methodology in an upcoming application. Moreover, the AESO sought to gauge stakeholder support for the proposed changes.
