California’s PG&E seeks approval for 423MW/1.7GWh of new battery storage projects

It’s the second major procurement from a California utility designed to comply with the CPUC’s order for 3.3 gigawatts of carbon-free resources to help meet grid reliability needs that will arise when four natural-gas-fired power plants retire next year to reduce their environmental harm to coastal waters.PG&E’s portfolio of new battery projects isn’t the biggest one meant to make up for those power plants, whose retirement has already been delayed by a year to allow clean energy replacement resources to be brought online. Earlier this month, utility Southern California Edison announced 770 megawatts, or nearly 3 gigawatt-hours, of storage from seven winning bids, most of them connected to existing solar farms. SCE has the largest share of procurement since it faces the more severe potential grid disruptions from closing the power plants.But PG&E’s new proposal does represent a major boost to a battery fleet that’s already set to be the largest in the world. PG&E’s major projects include a 300-megawatt/1,200-megawatt-hour project by Vistra Energy and a 182.5-megawatt/730-megawatt-hour project from Tesla being built near a natural-gas plant in the Monterey County community of Moss Landing.PG&E is now adding another 100 megawatts/400 megawatt-hours of battery plant from Vistra to be part of its new resource adequacy portfolio in the transmission-constrained South Bay/Moss Landing sub-area. It’s also adding three 50-megawatt/200-megawatt-hour systems to the existing 50-megawatt Diablo Energy Storage project being built by LS Power in Contra Costa County.PG&E’s new round of contracts, which must still be approved by the CPUC, is the third major storage deal to be announced just this month, including SCE’s projects and another nearly 3-gigawatt-hour procurement announced by Hawaiian Electric last week.[Jeff St. John]More: Vistra, LS Power top winners in PG&E’s 420MW storage procurementlast_img read more

Trelleborg in equipment supply deal for Johan Sverdrup

first_imgSwedish engineering company Trelleborg has been awarded a contract for the supply of elastomeric bearings for Statoil’s Johan Sverdrup development off Norway.Trelleborg’s elastomeric bearings are steel plate laminated and installed between the hull and the modules. They accommodate axial, shear, and rotational movement to keep the modules safe from impact, damage, and deformation.Similarly, they prevent the concentration of excessive strains and stresses around the mounting points of the modules and the hull caused by adverse sea and weather conditions.After production, Trelleborg’s engineering team check the design for specified loads and deformations and the fatigue performance using crack growth analysis calculations. The press used for the tests has a load capacity of 18,300 metric tons and weighing in at 600 tons.Located on the Utsira Height in the North Sea, 160 kilometers west of Stavanger, the Johan Sverdrup oil field is considered to be the largest offshore development in the past three decades. It will be operated by electrical power generated onshore.Daily production during the project’s first phase is estimated at 440,000 barrels per day, while peak production during Phase 2 is estimated to reach 660,000 barrels daily, around 25 percent of all Norwegian petroleum production.The riser platform – the largest of the four platforms comprising the project’s field center – will be the first of the Johan Sverdrup topsides to be installed in 2018. Trelleborg will manufacture and deliver 96 custom designed, sliding elastomeric bearings for use across the 23,000-ton platform’s six support points that will be in direct contact with the heavy transport vessel that will deliver the topside, which is being manufactured in South Korea, to the field.JP Chia, engineering manager for Trelleborg’s engineered products operation, said: “The Johan Sverdrup oil field is one of the largest ongoing projects in the North Sea. Therefore, it is vital that the finest quality bearings were used to successfully secure each of the platform’s support points.”last_img read more
