Transmission is a Valuable, Enabling Asset
Since 1941, Southwest Power Pool has been committed to ensuring the reliability of the North American bulk power grid. As it always has, SPP’s success today depends on a robust transmission infrastructure that is capable of transporting electricity from where it’s generated to where it’s most needed. Transmission is the enabling infrastructure that paves the way for myriad benefits to SPP’s stakeholders and their end-use customers.
Transmission Provides Economic Benefits
Investments in transmission – while seemingly costly in the short-term – pay big dividends to the region over time. Between 2004 and 2014, SPP committed to more than $9.3 billion in upgrades to the transmission network in its region. It’s estimated that these new and upgraded facilities will more than pay for themselves over their lifespans, and have already begun to benefit SPP’s stakeholders.
Xcel Energy – a provider of safe, clean, reliable energy in several states – announced in September 2015 that it would refund $18.6M to Texas retail customers. The driver of this decision? Lower fuel and purchased power costs, all made possible by investments in SPP’s transmission system.
In September 2015, SPP member company OG&E announced that its Oklahoma customers would see lower bills as the result of the benefits of SPP’s Integrated Marketplace. SPP’s own analysis showed that its market provided participants with net savings of $380M in its first year, none of which would be possible without adequate transmission facilities.
These are just two examples that validate the findings of a 2016 report published by Southwest Power Pool—called a “path-breaking effort” by the Brattle Group—which concluded that transmission investments in the SPP region from 2012-2014 had, on average, a benefit-to-cost ratio of 3.5 to 1. In other words, every dollar invested in transmission returns $3.50 in value to the region over the transmission facilities’ considerable lifespan.
Transmission Enables Access to Renewables
Transmission likewise enables access to more environmentally friendly generation like wind, solar and hydroelectric power. As recently as 2007, wind comprised less than one percent of SPP’s generation mix. At the end of 2015, following several years of heavy investment in transmission, wind represented more than 13 percent of SPP’s generation mix and energy consumption.
Transmission Addresses Growing Demand for Reliability
The stakes are higher today than ever. The need continues to grow for affordable, reliable electricity to serve new population centers. Diversified fuel types are needed to meet environmental and public policy standards. The entire utility industry is tied intrinsically to economic and national security, necessitating that we secure the grid against both physical and cyber-threats. The “internet of things” - the global network of electronics, sensors, and other objects that exchange data and power much of modern life- is likewise dependent on the availability of electricity, everywhere and all of the time. As SPP continues to modernize the electric grid in its region, seeking to meet each of these needs, we see more than ever a need for continued investment in transmission.
Transmission is an Investment in the Future
The good news is this: money spent on the transmission system in the SPP footprint is an investment. Studies—validated by actual, real-world examples—continue to prove the valuable benefits of new and upgraded transmission facilities, including adjusted production cost savings; access to diverse fuel types; improved market effectiveness; integration of renewable resources like wind and solar energy; reduced marginal losses; improved protection against storm-related outages; and more. Conservatively estimated, most transmission projects pay for themselves in a matter of years and provide net benefits of up to hundreds of millions of dollars over their considerable lifespan.
