Frequently Asked Questions

What is a brownout?

A brownout is a temporary reduction in voltage or power supply that can cause lights to dim and electrical appliances to malfunction. Brownouts are usually caused by high demand for electricity, and power companies may implement them to avoid a blackout or overload on the power grid. While brownouts are less severe than blackouts, they can still cause damage to electrical equipment, so it’s important to turn off appliances and devices during a brownout to prevent any damage.

Brownouts, also known as voltage sags, are a temporary and intentional or unintentional drop in voltage levels in an electrical power supply system. They are typically characterized by a decrease in voltage below the standard level but not a complete loss of power. Brownouts can be caused by various factors, including:

  1. Grid Overloading: When the demand for electricity exceeds the supply capacity of the electrical grid, voltage levels can drop, resulting in a brownout. This often happens during periods of high electricity usage, such as hot summer days when air conditioners are running at full capacity.
  2. Faulty Equipment: Malfunctioning or damaged electrical equipment, such as transformers, circuit breakers, or transmission lines, can cause voltage drops. Equipment failures can occur due to wear and tear, age, or environmental factors.
  3. Sudden Load Changes: Rapid and substantial changes in electrical load can lead to brownouts. For example, if a large industrial facility suddenly starts or stops a high-power process, it can affect the voltage stability in the local grid.
  4. Voltage Regulation Issues: Voltage regulation is the process of maintaining a stable voltage level within acceptable limits. Problems with voltage regulation systems or automatic voltage regulators (AVRs) can result in brownouts.
  5. Storms and Weather Conditions: Severe weather events like thunderstorms, lightning strikes, and heavy winds can cause power disruptions and voltage drops by damaging electrical infrastructure or causing power outages.

Brownouts, which are intentional or unintentional drops in voltage in an electrical power supply system, are quite uncommon in Alberta. The province’s electricity grid is robust and well-equipped to handle the typical demands placed on it. The electrical infrastructure includes a diverse mix of energy sources, such as natural gas, coal, wind, and hydro, providing a reliable energy supply to meet consumer and industrial needs.

The Alberta Electric System Operator (AESO), which is responsible for the day-to-day operation of the province’s power grid, has an excellent track record of managing the system to prevent situations where a brownout would be necessary. AESO’s real-time monitoring and market system allow for a balance between electricity supply and demand, helping to prevent voltage reductions.

Additionally, Alberta’s energy market design includes measures like demand response programs, which encourage consumers to reduce their electricity usage during peak times, further reducing the likelihood of a brownout. The province’s investments in infrastructure and maintenance, along with a rigorous regulatory framework, also play a key role in minimizing the chances of such occurrences. While no power system can be completely immune to the possibility of brownouts, in Alberta, they are an infrequent event due to the robustness of the system and the effective management of the electricity market.

A smart metre is an advanced metre that records your energy usage in real-time and sends the information to your utility company automatically. It allows you to monitor your energy usage and costs more accurately, and eliminates the need for manual metre readings. Smart metres also enable utilities to offer more innovative pricing plans, such as time-of-use tariffs, which charge different rates depending on the time of day or season.

No, your retailer (eg. Peace Power) is independent of your transmission and distribution company. This means that when you switch to us, only the energy rates you pay and the retailer you deal with changes – nothing to do with the delivery of energy to your home changes, and therefore there is no disruption.

In Alberta, Canada, the role of energy retailers is particularly distinct due to the province’s deregulated energy market. Energy retailers in Alberta act as intermediaries between energy producers and consumers, both residential and commercial. They purchase electricity and natural gas at wholesale rates and then sell it to consumers at retail prices.

Alberta’s deregulated market allows consumers to choose from a variety of energy retailers, rather than being limited to a single, regulated utility. This competition can result in more favorable rates, flexible contract terms, and specialized offerings such as green energy options. Some retailers offer fixed-rate plans that provide price stability, while others offer floating rates that fluctate with market conditions.

In this environment, energy retailers do not own the infrastructure for generating or distributing electricity or gas; those aspects are managed by separate entities. However, retailers handle customer service, billing, and often provide additional services like energy usage monitoring tools.

By participating in Alberta’s deregulated market, energy retailers play a key role in providing consumers with more choices and potentially better prices. They also have the opportunity to differentiate themselves through sustainability initiatives, such as offering electricity from renewable sources, thereby promoting greener energy solutions within the province.

Peace Power offers a variable rate for electricity, and both variable and fixed rates for natural gas. Fixed rates allow you to lock in for the length of the term (our term is 1 year), and our variable-rate plan allows you to take advantage when the prices are low. Note that the variable rate also rises so you may need to keep track of it from month to month to decide which plan is best for you.

Energy companies are entities that specialize in the production, distribution, and sale of various forms of energy, including electricity, natural gas, oil, and renewable energy sources. These companies play a vital role in meeting the energy demands of consumers, businesses, and industries. They invest in exploration, extraction, and refining processes to obtain fossil fuels like oil and natural gas, which are crucial for powering transportation, heating, and electricity generation. These companies often operate extensive infrastructure, including power plants, pipelines, and transmission networks, to efficiently deliver energy resources to end-users.
