Electricity is essential for nearly every aspect of daily life — so essential that we rarely think about how it’s produced and delivered to our homes. You might be surprised to learn that behind the scenes, a network of experts is working daily (and even by the minute) to anticipate how much electricity you need before you even use it.
We’re all connected to the electric grid, so ensuring the right amount of electricity for all involves a complex process of forecasting energy demand, planning for capacity and securing enough supply to meet Americans’ needs.
POWERFUL SOURCES
First, electricity must be generated at a power plant using either traditional sources, such as coal, natural gas or nuclear energy, or from renewable sources, such as solar, wind or hydropower.
At Prairie Land Electric distribution cooperative, we work closely with Sunflower Electric Power Corporation (Sunflower), our wholesale power provider, to secure enough electricity for our communities, using a diverse mix of energy sources to generate the power we deliver to your home or business. By maintaining a diverse energy mix — coal, natural gas, wind, solar and hydropower —Sunflower has options to ensure reliable power at a competitive cost.
On a larger scale, across the country, electricity supply and demand are managed through a market that includes long-term planning agreements, where electricity is bought and sold just like other common goods and services. Because Prairie Land Electric partners with Sunflower, which is also a cooperative, we are able to pool resources and expertise to deliver affordable power to our local communities.
Electricity supply changes throughout the day because demand fluctuates based on consumers’ needs. For example, residential members typically use more electricity in the mornings at the start of the day, and in the evenings when cooking dinner, running appliances and watching TV. Demand also increases when weather patterns change, such as extremely warm or cold temperatures.
MANAGING SUPPLY AND DEMAND ACROSS THE GRID
Across the country, other electric utilities are managing the same task of balancing supply and demand, which is why we have a larger network of key players in place to ensure enough power is delivered across the grid.
In most cases, the amount of electricity generated and sent to specific areas is coordinated and monitored by regional transmission organizations (RTOs) and independent system operators (ISOs). In Kansas, our RTO is the Southwest Power Pool (SPP), the power grid monitor for our 14-state region. SPP acts as an air traffic controller for the electric grid, taking measured steps to ensure there's enough supply to meet demand.
LOOKING AHEAD
As the energy sector undergoes rapid change, it’s important for all consumers to understand the basics of electricity supply and demand.
Electricity use in the U.S. is expected to rise to record highs this year and next, with the demand for electricity expected to at least double by 2050. At the same time, energy policies are pushing the early retirement of always-available generation sources, which could compromise reliable electricity.
Prairie Land Electric Cooperative remains committed to providing affordable, reliable energy to the members we serve. Together with Sunflower, we are evaluating our options to proactively address the rising demand and other potential challenges that could impact our local electricity supply.
Managing the balancing act of electricity supply and demand is a complex job, which is why we have a network of utilities, power plant operators and energy traffic managers in place to direct the electricity we need and keep the electric grid balanced.
