NV Energy plans to retire a 254-MW coal-fired unit in a power-constrained area of Nevada on the finish of 2021, 4 years forward of schedule. The firm will as a substitute buy 1,001 MW from new photo voltaic photovoltaic tasks outfitted with 100 MW of long-term battery storage, successfully doubling its complete renewable era from 14% in 2017 to 32% by 2023.
The plans are a part of the corporate’s 2019–2035 triennial built-in useful resource plan (IRP) accepted by the Public Utilities Commission (PUC) of Nevada on Dec. 21. As a part of the IRP, NV Energy evaluated 4 different provide plans primarily based on short-term wholesale energy purchases over the following 20 years.
According to NV Energy President Doug Cannon, the accepted provide plan, often known as the “Low Carbon Case,” strikes the corporate nearer to “a promise to our prospects that we’d double our renewable vitality by 2023.” The firm has made a long-term dedication to serve prospects with 100% renewable vitality, he famous.
A Planned Renewables Boost
As a part of its IRP, which NV Energy anticipates will “scale back prices over the following 30 years when in comparison with counting on wholesale energy markets,” the corporate will purchase energy via energy buy agreements (PPAs) from six new renewable energy tasks via the tip of 2021. These tasks, value a mixed direct funding of $2 billion within the state’s economic system, “signify the biggest renewable vitality funding in Nevada’s historical past, will even carry nice financial advantages to our state,” Cannon stated.
Three of those tasks will likely be situated in a constrained portion of the northern Nevada grid and three in southern Nevada. Some tasks are notable for his or her remarkably low energy costs.
Battle Mountain Solar Project. The 101-MW photo voltaic PV mission being developed by Cypress Creek Renewables contains 25 MW of battery vitality storage for a four-hour interval. NV Energy famous the battery capability on the plant “would be the nation’s largest DC-coupled mixed photo voltaic and battery storage system.”
Dodge Flat Solar Energy Center. The 200-MW photo voltaic PV mission east of Reno, is being developed by NextEra Energy Resources. That mission will combine 50 MW of four-hour-duration battery storage.
Fish Springs Ranch Solar Energy Center. The 100-MW photo voltaic PV mission north of Reno, additionally being developed by NextEra Energy Resources, will combine 25 MW of four-hour-duration battery storage.
Eagle Shadow Mountain Solar Farm. The 300-MW photo voltaic PV mission north of Las Vegas on land owned by the Moapa Band of Paiutes is being developed by 8minuteenergy Renewables. NV famous: “The Eagle Shadow Mountain Solar Farm is exclusive as a result of it’s presently the lowest-priced photo voltaic mission within the nation.” The mission features a flat $23.76/MWh fee all through its 25-year PPA.
Copper Mountain Solar 5. The 250-MW photo voltaic PV mission in Eldorado Valley, simply south of Boulder City, is being developed by CED Southwest Holdings, Inc., a subsidiary of Consolidated Edison.
Techren Solar V. The 50-MW photo voltaic PV mission in Eldorado Valley is being developed by Techren Solar LLC and will likely be adjoining to Techren Solar I, II, III and IV, which presently are within the development stage. When accomplished, the total Techren mission may have 400 MW.
At least 4 of the tasks would require community upgrades, which the PUC accepted on Dec. 21: Dodge Flat (at a value of $13 million; Fish Spring, $2.38 million; Eagle Shadow Mountain, $550,000; and Copper Mountain, $7.four million.
Closure of a Coal Unit in a Constrained Environment
Under NV Energy’s most well-liked “Low Carbon Case,” the corporate will shutter the coal-fired North Valmy Unit 1—a unit it acknowledges is “key to reliability throughout the constrained northern Nevada transmission system”—by December 2021.
NV Energy collectively owns the two-unit 522-MW North Valmy Generating Station close to Valmy, Nevada, with…
