The key challenge for the power sector is to invest heavily in the modernization of a century-old legacy system in an attempt to keep up with the soaring demands. Cengage Learning. RICH SEDANO: We're going to need to have a lot of changes in the system to make a very high-penetration renewable system work. But experts say the nation's power grid needs a lot of changes to make that happen. Interconnections can be tied to each other via high-voltage direct current power transmission lines (DC ties), or with variable-frequency transformers (VFTs), which permit a controlled flow of energy while also functionally isolating the independent AC frequencies of each side. Also, any improvements should address increasingly stringent regulations pertaining to environmental concerns. Each region delivers power at a nominal 60 Hz frequency. On October 17, 2009, the Tres Amigas SuperStation was announced to connect the Eastern, Western and Texas Interconnections via three 5 GW superconductor links.[8]. On the downside, this large and diverse network needs to grapple with complexities that arise on account of inter-operations between elements controlled by diverse groups. In the United States[1] and Canada,[2] national standards specify that the nominal voltage supplied to the consumer should be 120 V and allow a range of 114 V to 126 V (RMS) (−5% to +5%). View our portfolio here. This paves the path for increased capital expenditure not only to address the pressing needs for additional capacity, but also to ensure regulatory compliance in the face of serious environmental concerns. But the nation's grid is fragmented. [citation needed]. (2007). In Boulder, retiree Jerry Palmer is all about the future of 100% clean energy. Xcel has a ways to go to meet that goal, and as Grace Hood of Colorado Public Radio reports, it doesn't know how it's going to get there. The Western Interconnection stretches from Western Canada south to Baja California in Mexico, reaching eastward over the Rockies to the Great Plains. The Energy Policy Act of 1992 required transmission line owners to allow electric generation companies open access to their network[3][4] and led to a restructuring of how the electric industry operated in an effort to create competition in power generation. Now in All Tech Considered, making the technology that powers your home more green. It even has meteorologists on staff. Xcel Energy uses weather forecasts. These technologies are also physically different, and are used and manipulated differently on the power grid as a result. The regions are not usually directly connected or synchronized to each other, but there are some HVDC interconnections. HOOD: Ultimately, customers like Palmer are the ones who end up paying for local grid updates. Case Studies. Careers. … This text may not be in its final form and may be updated or revised in the future. In addition, some electrical devices cannot handle the lower 50 hertz cycle found in much of the world, and may experience difficulties. part of the Eastern Interconnection. The authoritative record of NPR’s programming is the audio record. NPR transcripts are created on a rush deadline by Verb8tm, Inc., an NPR contractor, and produced using a proprietary transcription process developed with NPR. We Insist: A Timeline Of Protest Music In 2020. Three other regions include the Texas Interconnection, the Quebec Interconnection, and the Alaska Interconnection. In return, each utility that agrees to share is allowed increased reserve capacity and use of larger and more efficient generators. In Colorado, Xcel is spending hundreds of millions of dollars to update its grid so it can better manage intermittent power sources, like rooftop solar on homes. Integration of renewable energy into a distributed energy generation and storage system is another technique that is being used to reduce demand, relieve transmission congestion, reduce thermal loadings and energy losses during peak hours, again with an objective of increasing efficiency and decreasing GHG emissions.
