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.
Baltimore Gas and Electric installs battery storage system to manage winter peaks
The 2.5 MW/9.74 MWh Hitachi Energy facility helped the utility avoid distribution upgrade costs and also participates in the PJM Interconnection.
Cadmium telluride solar cell based on indium gallium oxide emitter achieves 17.2%
Developed by the University of Toledo, the cell achieved the highest efficiency ever reported for flexible cadmium telluride solar cells to date. The device reached an open-circuit voltage of 861 mV, a short-circuit density of 27.8 mA/cm2, and a fill factor of 71.7%.
Solar generated 5.5% of U.S. electricity in 2023, a 17.5% increase
Solar generation grew by 17.5% compared to 2022, albeit at a lower rate, adding just over 33 TWh of generation compared to the 40 TWh added in 2022.
Calculating potential impact of EPA’s $7 billion Solar for All program
Solar for All can jumpstart the solar market and expand the benefits of solar far beyond the initial five years of the program. Clean Energy States Alliance notes that after the award decisions are announced, additional states will be evaluating strategies and more households will benefit from this funding over time.
MIT research provides roadmap to perovskite passivation
In previous work, research teams developed methods for passivation, but there wasn’t clear understanding of how the process works. The new MIT study provides details on how to passivate the material’s surface so that the perovskite no longer degrades so rapidly or loses efficiency.
Grid operators in California and Texas earn “B” grades, others score poorly
With two million megawatts of generation and storage projects awaiting interconnection studies across the U.S., a report gives grid operators grades for their interconnection processes ranging from B to D-.
U.S. solar up 52% in 2023 as nation deploys 35.3 GW of capacity
Bloomberg NEF says U.S. clean energy generation grew by 0.9%, with wind and hydro generation falling and solar generation growing 15.4%.
NREL finds 100% renewable scenario improves LA air quality and health
NREL modeled that LA and surround counties could save over $4 billion from improved health outcomes. The most significant reductions in emissions resulted from electrification and infrastructural changes to the non-power sector, such as transportation and buildings.
All floating PV technologies at a glance
An international research team has produced a comprehensive overview of more than 300 works of published literature on floating PV, spanning 2013 to 2022. The scientists laid out the benefits and challenges of the technology and pointed to gaps that should be filled with future studies.
