Amazon Web Services helps Duke Energy complete power flow studies in hours, not months
Adding residential solar or commercial-scale electric vehicle chargers on a utility’s distribution feeder may require the utility to conduct power flow calculations. Duke Energy can now complete those studies in hours, an Amazon executive said at a policy forum held by ACORE.
Energy Vault connects commercial-scale gravity energy storage system in China
Energy Vault has connected its 25 MW/100 MWh EVx gravity-energy storage system (GESS) in China. Once provincial and state approvals are obtained to start operating, it will become the world’s first commercial, utility-scale, non-pumped hydro GESS. Meanwhile, its partners China Tianying (CNTY) and Atlas Renewable Energy have begun construction on three grid-scale GESS in China.
Online map for ground mounted solar plants in China
The China Agricultural University has created an online dataset presenting all PV plants deployed in China at the end of 2020. The tool shows China ground mounted solar facilities occupied a surface of 2,467.7 km2 at the end of December 2020.
Serbia to auction at least 400 MW of wind, solar
The Serbian government plans to launch its second renewables auction this year in a bid to procure at least 400 MW of wind and solar power.
Renewable energy adoption taking off in Rwanda
The European Union has secured a critical raw materials deal with Rwanda, expanding collaboration between the two sides – particularly in the solar sector. A friendly regulatory environment deserves credit for helping to fast-track the adoption of solar, according to local analysts.
Socomec releases new modular energy storage system
Socomec says its new modular energy storage system includes a converter and up to six battery cabinets. At maximum capacity, it can store 1,116 kWh.
Swedish virtual power plant software developer secures funding

UK researchers identify optimal heat pump design minimizing system transition costs
Researchers led by the Imperial College London have analyzed the effects different kinds of air-to-water heat pumps will have on the UK energy system, based on their coefficient of performance and price. They also identified a point of diminishing returns, after which it is more cost-effective to invest in centralized energy generation and storage.
Trina Storage releases 4.07 MWh energy storage system
Trina Storage has developed a 4.07 MWh energy storage system featuring its in-house 306 Ah lithium iron phosphate battery cells, configured with 10 racks of four battery packs.
Bifacial agrivoltaics for olive groves
A Spanish-Italian research team has investigated different system configurations for bifacial agrivoltaic solar arrays deployed in olive groves and has found that the solar modules’ tilt angle has a significant impact on power yield while their height plays a crucial role on increasing agricultural yield.
