Overview of grid codes identifies CEI 0–21 standard as potential international benchmark
Conducted by Italian scienitists, the analysis includes standards such as IEC 61727, the US EREC G83/2 Recommendations, Germany’s VDE-AR-N 4105, China’s GB/T 19964-2012 and GB/T 20,046, Italy’s CEI 0-21, Australia’s AS 4777.2, and New Zealand’s AS 4777.2 standards, as well as the United States’ IEEE 1547.
Study shows grid behind recent large-scale battery fire in Australia
Genex Power, the owner of a 50 MW/100 MWh battery system that caught fire in the Australian state of Queensland on Sept. 26, says the blaze was triggered by issues on the grid side of the Tesla Megapack battery unit.
Record-high wind energy production in Italy while Euro electricity prices slide
The Italian market set a record high of 846 GWh of wind energy generation during the first week of November. Meanwhile, European electricity demand decreased over the same period and the MIBEL market registered 19 hours of €0.00/MWh ($0.00/MWh) prices.
New research sheds light on off-grid solar costs in remote villages
An international research group has assessed the economic feasibility of exclusively powering remote villages in Pakistan with off-grid solar-plus-storage projects. They said that their proposed system configuration has a “justifiable” net present cost.
Novel architecture for heterojunction copper bismuth oxide solar cells
Researchers in Bangladesh have simulated a solar cell based on a copper bismuth oxide material, used as an absorber, with a hole transport layer made of copper(I) oxide (Cu2O). In the experiment, the device achieved a power conversion efficiency of 29.2%, an open-circuit voltage of 1.02 V, a short-circuit current density of 32.49 mA/cm2, and a fill factor of 87.91%.
India’s NHPC allocates 3 GW of solar for $0.030/kWh
NHPC has allocated 3 GW of solar capacity at a rate of $0.030/kWh to developers who can set up projects connected to the interstate transmission system across India.
NREL forecasts rising US utility-scale solar costs, falling residential prices
The US Department of Energy’s National Renewable Energy Laboratory (NREL) has updated its annual cost modeling tool in light of the US Inflation Reduction Act (IRA). It has identified higher labor costs for utility-scale solar projects and falling hardware costs due to new manufacturing tax credits.
Israel’s Teralight to buy 16.5 MW rooftop PV portfolio
Israeli developer Teralight says it is buying 16.5 MW of solar projects for ILS 25 million ($6.4 million) from gas supplier Electra Power. It expects to generate ILS 320 million of income over the lifetime of the projects.
Dyness introduces 312 kWh battery
China’s Dyness says its new 312 kWh storage system uses 375 Ah lithium iron phoshate batteries. It also claims that its cooling system reduces average temperature increases by 6 C.
BYD unveils new agrivoltaics module
Chinese module maker BYD is producing a new bifacial monocrystalline panel at its manufacturing facility in Sao Paulo, Brazil. The module has a power output of up to 355 W and a conversion efficiency of 16.33%.
