Deregulation in Alberta

The right choice in Alberta's deregulated power market

The right choice in Alberta’s deregulated power market

Today, the wholesale electricity market and retail services are the two components of the electricity industry that are deregulated, giving consumers a wide variety of choice.

What is deregulation?

What is deregulation?

Back in the late 1990s, the Alberta government made the decision to turn over future investment decisions in the electricity sector to private capital. What that meant was public money would no longer be used to help finance and build new power plants in the province. It also meant companies, such as TransCanada, would need to make prudent decisions on timing and locations for new power-generation facilities in Alberta. The power market largely exists in the same form today as it did when it started back in 2001. More than 6,150 megawatts (MW) of new power generation has been built in Alberta since 2004, with zero government debt incurred as a result. Today, the wholesale electricity market and retail services are the two components of the electricity industry that are deregulated, allowing consumers a wide variety of choice. The wires (transmission and lines and distribution system) system remain as the only regulated components of the market. Graphic: Regulated and Deregulated components of the Alberta Power Market

How the electricity market works

How the electricity market works

The electricity market in Alberta is known as an “Energy-Only” market. Unlike some jurisdictions, where generators are provided with a long-term capacity payment from a government or a contract from a public utility, Alberta’s generators are paid based on what they earn from the Power Pool of Alberta (PPoA). The PPoA is essentially a clearing-house for electricity generators managed by the Alberta Electric System Operator (AESO), where all the supply available in the market is offered in for every hour and “stacked” by price from the lowest to the highest. Supply Stack Price & Demand (Example and Highlights)

Power Generator Supply Volume (MW) Price Offered ($/MWh) Demand Volume (MW)
Generator 8 100 $500 9,150
Generator 7 50 $150 9,050
Generator 6 100 $100 9,000
Generator 5 200 $60 8,900
Generator 4 1,200 $50 8,700
Generator 3 2,500 $20 7,000
Generator 2 1,500 $10 4,500
Generator 1 3,500 $0 3,500

In Alberta, generators can offer to sell power for any price between $0.00/MWh and $999.99/MWh. Plants are dispatched on, or dispatched off, by the AESO’s System Controller based on the price the generator has attached to its volumes. Since electricity can’t be stored, the supply of power in the market must always exactly meet the demand for power in the market. This means the System Controller is constantly balancing these two components and can mean the price for electricity can change by the minute, or even by the second. As an example (highlighted above), if demand in the province was 8,900 MW, the price in the province would be set at $60/MWh and every MW of volume that is priced lower than $60/MWh would be “dispatched on” and receive the price of $60. Because the prices and volumes offered by suppliers can change every two hours, there can be a significant amount of competition between generators on a daily basis to ensure plants are dispatched on. Healthy amounts of supply and low demand typically equates to low prices in the market. At the same time, when power generation is offline and/or demand for electricity peaks prices tend to rise.

Overcoming the volatility of power pricing

Overcoming the volatility of power pricing

Since electricity supply and demand always have to be in balance, changes in either of these factors tend to impact prices — sometimes drastically. In an Energy-Only market, periods of reduced supply and sustained high prices can serve as a signal to generators that it might be time to build new power plants. But that doesn’t mean you need to be exposed to those high prices. In the short term, TransCanada offers a variety of tools to keep your business insulated from that volatility.
