US Grid-Battery Costs Dropped 70% Over 3 Years

An anonymous reader quotes a report from Ars Technica: In recent years, the cost of solar and wind energy has declined precipitously, which has accelerated the growth of these renewable energy technologies. Increasingly, utilities are now planning for a future grid dominated by solar and wind. That will require changes in grid management and transmission upgrades as well as the addition of storage to smooth out the supply from variable generators. Grid storage is still pretty early days, but we're already seeing huge cost reductions as the industry matures. The US Energy Information Administration (EIA) highlighted this recently, showing that grid-scale battery-project costs in the United States dropped 70 percent in just a few years. Between 2015 and 2018, average project costs decreased from $2,152 per kilowatt-hour of storage to $625. Costs will need to drop much more for grid batteries to scale, but that's a huge improvement in a short period of time. By the end of 2018, the US had 869 megawatts of battery power capacity and 1,236 megawatt-hours of energy capacity. (Power is the rate at which the batteries can supply electricity, while energy is the total amount it can supply when going from full charge to empty.) EIA also has installation data for 2019, which saw the addition of another 150 megawatts/450 megawatt-hours. And in just the first seven months of 2020, yet another 300 megawatts of power capacity were installed. EIA doesn't see this slowing down. It expects installed battery storage to increase by 6,900 megawatts "in the next few years" -- a figure ambiguous enough to allow for a rapid spike in planned projects.

UK Mobile Networks Banned From Selling Locked Phones

The UK's mobile networks are to be forbidden from selling phones locked to their services from December 2021. From a report: Regulator Ofcom said unlocking handsets could often be a complicated process, and this was discouraging owners from switching providers at the end of their contracts. The networks have previously suggested that locking devices helps deter theft and fraud. But the watchdog noted some companies had already abandoned the practice. Among those companies affected are: BT and its EE mobile division, Vodafone, Tesco Mobile, O2, Sky, Three and Virgin already only sell unlocked handsets. "[It] will save people time, money and effort -- and help them unlock better deals," said Ofcom's connectivity director Selina Chadha. Vodafone has already responded: "We stand ready to implement these changes when they come into force." EE added: "We'll work with Ofcom to comply with its guidelines."
