Some 50,000 houses in South Australia will be equipped with solar panels and Tesla batteries, the state government announced Sunday, in a move to turn decentralized gensets in buildings a giant interconnected Virtual Power Plant (VPP). According to Tesla, the VPP will have 250-MW of solar energy and 650 MWh of battery storage.
Operators of Drax, the UK’s largest coal power station, are staging a series of events to inform the wider public about plans to repower up to two of the plant’s remaining coal-fired units with gas and adding a large battery storage system. If the repowering proceeds as planned, Drax will be expanded with two combined-cycle gas turbine (CCGT) power units with a combined capacity of 3,600-MW and a battery storage system of up to 200-MW.
Jan 11 – Kilkenny County Council is processing an application Greener Ideas, a joint venture set up in 2009 between Bord Gáis Energy and Mountside Properties,for the construction of a 100MW battery energy storage system. Initially the project partners intended to develop an open-cycle gas turbines power plant on the site which is now listed for the battery project.
Portuguese project company Graciolica, backed by its Danish majority shareholder, has placed an order with Greensmith Energy for an integrated energy management system (GEMS) for its microgrid power unit in the Azores. The hybrid renewable plant will supply 1-MW of solar and a 4.5-MW wind power to the island power grid. The plant is slated to start operations in mid-2018.
Commenting on the UK Government’s decision to de-rate battery storage ahead of the Capacity Market auction in February next year, UK Power Reserve (UKPR) said it “accepts and understands” this move while remaining confident about the future of battery storage in Britain. UKPR also underlined its goal to bring 120MW of battery storage online before 2020.
Cost and performance of battery technologies will not only be shaping customer acceptance of electric vehicles in the coming years, but also determine how easy it will be to integrate renewable energy into the grid. Tracking the relation between the dramatic drop in prices for batteries and their usage, IEA analysts say “for each doubling of output, lithium ion battery prices have been getting 19% cheaper.”
A new chemical composite, developed by researchers at MIT, can be used to store the energy from sunlight or any other heat source in a battery-like system that is capable of storing thermal energy and releasing it on demand. The new solution combines phase change material (PCM) with molecular switches that can be adjusted with light, enabling the overall system to store thermal energy at lower melting points than the original material.
Nov 9 – Plans by Drax Power to upgrade two units at its 2,000 MW coal- and wood pellet-fired power station to run on natural gas have gone to public consultation. The operator said it also notified the UK planning inspectorate about its intention to build a new natural gas pipeline and a 200-MW battery storage at the site near Selby, North Yorkshire.
Uncertainty about future battery technology, government policies, consumer preferences make it difficult to predict the long-term effects that both battery electric and plug-in hybrid vehicles (EVs) may have on worldwide energy consumption. In 2015, sales reached 1.2 million worldwide which is less than 1% of all vehicles used globally, but this level could almost double by 2040, according to EIA analysis.
Intermittency issues of wind and solar power supply are feared to jeopardize the stability of the U.S. power grid. To remedy this issue scientist at the Massachusetts Institute of Technology (MIT) have developed an “air-breathing” battery storage that, at the cheapest, run about $100/kWh and functions only in certain locations.
