Did you know that the Western United States is one of the only regions of the country without a fully interconnected electrical grid?
For most of the U.S., states and utilities work together to create what is called a regional transmission organization or an RTO. Instead of disparate entities delivering power within small areas, an RTO manages the entire electric system – from the power plant through the transmission wires to the customer – in a more efficient, affordable way.
In the Western U.S., there are 38 independent entities balancing the grid through individual electric service areas. That means 38 different companies, 38 different pricing structures, and at least 38 potential inefficiencies for us reaching our goals of more affordable, reliable and clean electricity.
An RTO is designed to automatically dispatch the lowest-cost electricity available.
Using the latest technology, an RTO will balance supply and demand on the grid across the West – creating a more reliable system, particularly in periods of extreme weather and increased demand.
A west-wide approach to balancing our grid makes it easier to integrate the variable output of renewable power like wind and solar.
Lower electricity prices and a reliable system is a significant draw for companies looking to locate in the West.
Leveraging the latest technology and breaking down barriers between the states will open up the energy market to the cleanest, lowest cost electricity for customers at any given time, as well as limit the amount of new power plants needed overall. A Western RTO would also remove many existing transmission constraints, allowing power to more seamlessly reach those who need it, and instead invest in our transmission infrastructure in the places with the largest benefit to the West.
Our electrical system continues to increase in complexity every day, while at the same time we’re seeing more and more pressures on the grid. This means we must act now to prevent reliability concerns among Western states while maintaining our western independence.
A regionally connected and coordinated power grid means more effective deployment and increased development of diversified energy portfolios. For example, wind energy developed in Nevada could be used in Colorado, just as solar power captured in Arizona can then be purchased and used in other states. More renewable energy on the grid means it is easier for utilities, states, counties, cities and large customers to meet their decarbonization goals – creating a cleaner future for us all.
