Stanford professors Paul R. Milgrom and Robert B. Wilson were awarded the 2020 Nobel Prize in economics for developing a new auction theory and new auction formats for goods and services. Their findings were already successfully used in the electricity energy sector and may now meet the challenge on how to better shape clean energy procurements.
Huanghe Hydropower Development has connected a 2.2 GW solar plant to the grid in the desert in China’s remote Qinghai province. The project is backed by 202.8 MW/MWh of storage.
Researchers at the University of Rhode Island have suggested homeowners are prepared to pay $279 per year to avoid living within a mile of a large-scale solar plant. Other research has contrary findings.
Built in Gangba County, in Xigaze, Tibet, the 40 MW/193 MWh facility was deployed at more than 4,700m above sea level and is functioning as a demonstration project for the ancillary services the technology could offer the Tibetan grid.
The U.S. polysilicon manufacturer has acquired DuPont’s trichlorosilane business, in a move that will help it cut production costs and control supply.
A study into the benefits of linking solar with hydro in a full hybrid system configuration has found global potential of 7,593 GW, for an estimated annual power generation of 10,616 TWh and a 20% reservoir coverage.
Solar curtailment might become a valuable aspect of future PV deployment, particularly if grid operators start focusing on ‘curtailment management’ instead of ‘curtailment prevention.’ Management would include measures such as flexible generation, storage, load flexibility, and regional coordination.
The US microinverter producer and the German panel maker have launched a residential glass/glass PERC module equipped Enphase IQ 7+ device. The 60-cell PERC module is available in three versions with power output ranging from 320 to 330 W and efficiencies of 18.8% to 19.4%.
According to the product sheet, the new series has dimensions of 2,219×1,765x40mm and weighs 43.5kg. Efficiency reportedly ranges from 20.1-20.8% and the module features a 12-year product warranty and 25-year linear power output guarantee.
