Nobel Prize-winning auction geniuses want to apply their findings to renewables

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.

World’s largest solar plant goes online in China — 2.2 GW

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.

Rhode Island economists attempt to put a price on NIMBYism

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.

World’s highest utility-scale solar plus storage project

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.

Hemlock Semiconductor becomes vertically integrated polysilicon maker

The U.S. polysilicon manufacturer has acquired DuPont’s trichlorosilane business, in a move that will help it cut production costs and control supply.

NREL projects up to 7.5 TW of global, hydro-linked floating PV potential

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.

NREL scientists encourage ‘optimal’ PV curtailment

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.

Enphase and Sonnenstromfabrik unveil AC solar panel

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%.
