AES breaks ground on largest battery storage unit in the U.S.

first_img FacebookTwitterLinkedInEmailPrint分享S&P Global Market Intelligence ($):More than twice the size of the largest battery system currently operating in the United States, the AES Alamitos Energy Battery Storage Array in Long Beach, Calif., signals much bigger things soon to come for electrochemical energy storage on U.S. power grids.This first 100-MW/400-MWh phase of the system, on which owner AES Corp. recently broke ground, is underpinned by a 20-year contract with Southern California Edison Co. starting in December 2020. Relying on lithium-ion batteries, the system could eventually triple in size with its permit to expand to 300 MW.Among contracted U.S. battery storage projects, the Alamitos array is surpassed by Vistra Energy Corp.’s 300-MW/1,200 MWh Vistra Moss Landing Energy Storage system, near Santa Cruz, Calif., which has a 20-year agreement for the entire installation with Pacific Gas and Electric Co., or PG&E. Co-located at another major combined-cycle gas plant, Vistra’s Moss Landing CC, the project is also scheduled to start operations in December 2020.Planned to come online at the same time and in the same place is the PG&E Corp. subsidiary’s 182.5-MW Tesla Moss Landing Battery Energy Storage Project (Elkhorn), an approved utility-owned project to be supplied by Tesla Inc. Other major utility-scale battery projects, some coupled with solar farms, are planned around the country, including in Arizona, Colorado, Florida, Hawaii, Nevada, New York and Utah.While the PG&E projects could see delays, or even cancellations, related to the utility’s ongoing Chapter 11 bankruptcy and restructuring process, batteries could ultimately satisfy “a substantial portion of U.S. peak capacity needs,” the U.S. Department of Energy’s National Renewable Energy Laboratory, or NREL, concluded in a new report, “The Potential for Battery Energy Storage to Provide Peaking Capacity in the United States.” Assuming current conditions and demand patterns on the U.S. grid, the analysis identified a practical energy storage peak power potential of about 70,000 MW. That includes approximately 28,000 MW from four-hour battery storage arrays, 8,000 MW from six-hour storage systems and 34,000 MW from eight-hour storage projects.More ($): AES starts building largest battery peaker, highlighting technology’s potential AES breaks ground on largest battery storage unit in the U.S.last_img read more

Govt should develop a long-term plan to manage oil

first_img…an “old problem” for resources to be mismanaged – HindsAssociate Professor and political activist David Hinds is imploring the government to not make the same mistake as Trinidad and Tobago did by not developing a long-term plan to manage its oil resource.Dr David HindsAlthough the discovery of oil is welcoming, Hinds in an interview with Guyana Times stated that government should start taking the necessary steps towards the proper management of the resource. He highlighted that it is an “old problem” for Guyana’s resources to be mismanaged, in terms of foreign investors being the prime beneficiaries of the resources.He said this “old thorn” has not been removed because Guyana is not single-minded about confronting and solving the issue of Guyana’s resources being mismanaged.“For example, we have our gold. However, there is no processing plant to refine our gold and so the gold is extracted in its raw state and shipped out to be refined. And what do we gain – a percentage,” he explained, noting that it is the same with other resources.Recently, ExxonMobil discovered that the second exploration well in the Stabroek Block offshore Guyana has a recoverable resource of between 800 million and 1.4 billion oil-equivalent barrels. The wells are located approximately 193 kilometres (120 miles) offshore. The block is 26,800 square kilometres (6.6 million acres).Esso Exploration and Production Guyana Limited holds 45 per cent interest in the Stabroek Block; Hess Guyana Exploration Ltd holds 30 per cent interest and CNOOC Nexen Petroleum Guyana Limited holds 25 per cent interest.ExxonMobil is the largest refiner and marketer of petroleum products while its chemical company is one of the largests in the world.According to Hinds: “There is always the overemphasis on attracting foreign investment. I think the same emphasis should be put in developing internal mechanisms and economic structure. So we should invest in small businesses, in our local investors.”Hinds alluded however, to the deficiency of the skilled human resources and to that end insisted that before Guyana begins to envisage managing oil on its own, it should start investing in its people first. He stated that government should encourage Guyanese to develop the skills necessary to build an economy around oi: “We should start investing in having locals trained in oil engineering for the future….we would need lawyers to handle cases of petroleum issues.”Education Minister Rupert Roopnaraine had disclosed that he had proposed to the authorities of the University of the West Indies (UWI), St Augustine Campus, to develop a petroleum engineering programme that would prepare Guyana to manage its potential oil industry.Petroleum engineering is the study of the extraction of oil, gas and other natural resources from the earth. This is accomplished through the design, drilling and operation of wells and well systems, and the integrated management of the underground reservoirs in which the resources are found.Hinds suggested that Guyana needs to start envisaging a whole new economy around oil and start now: “It is not about pumping the oil out from the ground and selling it and getting the money…if Guyana is going to benefit from oil we have to build up an enabling economy…an offshoot economy.”Oil refineryThe Associate Professor indicated that if Guyana cannot develop its own oil refinery, then the country should partner with Caricom countries to construct one. “That is the way to go…that is why we have Caricom…” he stressed.“It would be nice if we can have our own oil processing here but if we cannot do it by ourselves then we can partner with sister Caricom countries to do,” he said, explaining that this is what a single market is about.He noted that if Guyana and Trinidad could develop an arrangement where they can both manage a future oil refinery in Guyana, then both Guyanese residing in Trinidad and Guyana would benefit.“It is either we have our own processing plant or we do it through a regional emphasis,” Hinds stressed.Ministers of Natural Resources and Finance Raphael Trotman and Winston Jordan are currently visiting Uganda to gain knowledge on the strategies that country has employed to manage and develop its oil resource.last_img read more
