Peak alerts are a forward-looking notification that anticipated peak times on the grid
A peak alert is a forward-looking notification that alerts users of anticipated peak times on the grid. Peak alerts are an energy management tool that helps users reduce their energy spend. When the demand for electricity is much higher than normal, it increases the cost of electricity and puts a strain on the nation's electric grid. Peak alerts are shared with members to encourage them to lower their electricity usage when demand is high, which helps manage the price paid for power and keeps costs low.
The Peek app and monitor display the user's current electricity price tier, making it easy to shift electricity usage to when it is cheaper. Users can also receive energy-saving tips and information about utility programs and money-saving offers. The app provides simple 'traffic light' logic, where users can quickly glance at the monitor or app to know which price tier they are in.
The Peek app also sends alerts when there are rate changes or peak pricing events. These alerts can be sent the day ahead of the predicted peak or on the day of the predicted peak, along with the forecasted duration of the peak. During these times, it is recommended to wait to run large appliances like washers and dryers.
By reducing electricity usage during peak times, users can make smart decisions to reduce grid-based electricity usage and their energy costs. This also helps reduce the strain on the grid and enables grid operators to build and deploy less carbon-emitting generation.

Alerts are triggered when system-wide demand is at peak levels
For example, South Central Power purchases electricity based on the total number of kilowatt-hours used by its members and the largest demand for electric power during any one-hour increment. When a new "peak demand" is set, it can mean a higher rate for electricity for the rest of the year. Therefore, South Central Power shares peak alerts with its members, encouraging them to reduce their usage during those times. This helps to manage the price they pay for power and keep costs low.
Similarly, Schneider Electric's Peak Alert Notification Service triggers alerts when system-wide demand is forecast to be at peak levels. This allows facility leaders to determine whether to shed load during that specific time or use on-site generation assets. Peak alert notifications can be sent the day ahead of the predicted peak or on the day of the peak. The forecasted duration of the peak will also be provided in these alerts. If a business can respond by reducing energy consumption pulled from the grid, then a peak alert notification service could help it reduce its Peak Load Contribution (PLC) and save money on energy bills.
Peak alert responses can also help to reduce the grid's overall environmental impact. When energy demand is at its highest, more expensive generators are needed to meet demand, and these tend to be more carbon-emitting. By reducing the strain on the grid during these times, grid operators can build and deploy less carbon-intensive generation methods.
Reducing peak demand is an important cost-saving measure for small and medium enterprises (SMEs) as electricity tariffs often include a demand charge determined by the yearly highest demand. Therefore, SMEs are incentivized to reduce peak demand and create a peak-hour action plan as part of their energy management strategy.

Alerts can help reduce energy consumption and costs
A peak alert is a notification that warns of anticipated peak electricity demand times. These notifications are an important energy management tool that can help reduce energy consumption and costs for both consumers and providers.
During periods of high demand, electricity providers are forced to turn to more expensive generators to meet the demand for electricity. This results in increased costs for providers, which are then passed on to consumers in the form of higher electricity rates. Peak alerts aim to reduce this demand by encouraging consumers to lower their electricity usage during these times. This, in turn, helps to curb the need for costly generators and keeps prices low.
For consumers, peak alerts provide an opportunity to make small changes that can have a significant impact on their energy bills. For example, consumers can be incentivized to shift their energy consumption to off-peak times by using the delayed start feature on appliances or waiting until late evening to run the dishwasher. They can also make simple adjustments such as turning their air-conditioning thermostat up a few degrees or using less hot water. These actions not only help reduce the individual's energy costs but also contribute to lowering the overall demand during peak times.
Businesses, too, can benefit from peak alerts by creating a peak-hour action plan as part of their energy management strategy. By understanding how peak alerts work and their interplay with supply contracts, businesses can make informed decisions to reduce their energy costs. For instance, they may choose to shed load during peak times or leverage on-site generation assets. Additionally, peak alerts can help businesses reduce their environmental impact by encouraging the use of less carbon-emitting generation methods.
Overall, peak alerts provide valuable information that empowers both consumers and businesses to make smarter energy choices. By reducing demand during peak times, individuals and organizations can work together to curb the strain on the grid, lower electricity costs, and even contribute to a greener energy future.

Peaking power plants supply power occasionally at a higher price per kilowatt-hour
A peak alert is a notification that warns of anticipated peak times on the electrical grid. These notifications are an energy management tool that helps users reduce their energy spend. When the demand for electricity is much higher than normal, it increases the cost of electricity and puts a strain on the electrical grid.
Peaking power plants are typically gas turbines or gas engines that burn natural gas. They are able to quickly start up and ramp up their energy output during times of high demand. Due to the fluctuating conditions, the equipment and fuels used in base load plants are often unsuitable for use in peaker plants. This means that nuclear, waste-to-energy, coal, and biomass plants are rarely, if ever, operated as peaker plants.
Because of the high cost of building an efficient power plant, it does not make economic sense to build a peaker plant to run for a short period or on an irregular schedule. As a result, peaker plants are generally less efficient than base load plants and more expensive to operate. This is why they supply power occasionally at a higher price per kilowatt-hour.
The use of peaker plants is becoming less common as countries move away from fossil fuel-based energy sources. In some places, peaker plants have been replaced by battery storage solutions, such as the Tesla Megapacks used by the New York Power Authority.
To reduce the need for peaker plants, grid operators encourage energy flexibility. This can be achieved through demand response programs or price signals that discourage energy use during peak times. By reducing demand during peak hours, the overall cost of electricity can be lowered.
