Rewiring Alberta’s electricity market

Alberta’s government is making changes to the province’s electricity market rules to restore the balance between affordability, reliability and sustainability.

Alberta’s government is modernizing the province’s electricity system to put Albertans first, restoring the balance between affordability, reliability and sustainability. To achieve this, Alberta’s government continues to work with its partners on power market reforms.  Alberta’s transmission policies are also being updated to improve reliability, increase efficiency, protect ratepayers, and align Alberta with other jurisdictions. Alberta’s government is committed to the province’s unique competitive electricity market, which provides consumers with choice and makes the province a premier destination for investors.

Alberta’s electricity system was designed for a small number of baseload power plants generating reliable electricity. In 2016, Alberta’s accelerated coal phase out was rushed through without proper due diligence. With a growing supply of intermittent renewables instead of natural gas, the province’s power grid and prices can become as volatile as the weather.

The thousands of kilometres of new transmission lines that were required to connect renewables added costs for Albertans, and back-up sources are required to keep the lights on. As demand for electricity only continues to increase, it’s expected that Alberta’s need for electricity could more than quadruple in the coming decades. It is critical that Alberta’s government make changes now to ensure the affordability, reliability, and sustainability of the provincial grid in the decades to come as demand surges.

“Albertans deserve a modern electricity system that prioritizes affordability and reliability. As our electricity supply mix evolves so should our policies, and these updates to transmission policies are essential to ensuring Albertans are well-served by our electricity system for years to come.”

Following three years of engagement with industry, Alberta’s government is making changes to ensure the province’s ratepayers are no longer burdened with the full costs of building new transmission lines. Instead, costs for new transmission infrastructure will be assigned on a cost-causation basis going forward. This will incentivise new power plants to be built in optimal locations that take advantage of existing infrastructure, saving costs for both Alberta ratepayers and job creators. As a result of engagement with industry, Alberta’s government is aligning the province with other jurisdictions by giving the Alberta Electric System Operator (AESO) more market-based tools to increase the efficiency of the province’s grid, prioritizing the use of pre-existing infrastructure.

Updating Alberta’s Transmission Regulation is a significant and necessary step in modernizing the province’s electricity system. To enhance grid reliability, Alberta’s government is also making changes to streamline the process to build and maintain connections between our electricity grid and other jurisdictions. This will reduce red tape and enable critical improvements to happen more quickly. This will also help improve reliability by restoring the electricity grid connections between Alberta and British Columbia, as well as expanding the connections between Alberta and Saskatchewan.

“This is a positive milestone borne out of significant engagement and consultation with industry stakeholders, our partner agencies and the Government of Alberta. We appreciate the tremendous investment of time and effort that everyone has put into this process to reach this point, and we look forward to additional engagement in 2025 to further the detailed market design.”

Over the past year, the AESO has engaged extensively with industry on the technical design of a Restructured Energy Market with direction from Alberta’s government. A key aspect of these market reforms includes moving to a day-ahead market, where power generators will be required to commit their power on the previous day, rather than a couple of hours beforehand, making the system better positioned to respond to power fluctuations. This will increase reliability and stability, helping reduce the risk of potential grid alerts. With these changes, Alberta’s government is ensuring that reliability is prioritized, strengthening the grid so that Albertans can get the power they need regardless of the weather.

“Market design features like a day ahead market can help significantly reduce the likelihood of future grid alerts and will ensure that all necessary generators needed to meet electricity demand are online to provide power.”

Minister of Affordability and Utilities Nathan Neudorf has sent a letter to inform the AESO of the government’s latest decisions on changes to the Transmission Regulation and further guide the ongoing technical design of a Restructured Energy Market. Alberta’s government intends to bring forward legislation to support these changes in the new year. In the meantime, the temporary measures enacted by Alberta’s government on July 1, 2024 will continue to protect Albertans, ensuring reliable power and predictable utility bills.

Quick facts

• The Alberta Electric System Operator (AESO) manages and operates the provincial power grid on behalf of Albertans.
• The Market Surveillance Administrator (MSA) is a public agency that protects and promotes the fair, efficient and openly competitive operation of Alberta’s electricity and retail natural gas markets.
