A critical moment for Brazilian energy storage
A national procurement round for energy storage systems, planned in the second half of the year, is at risk of lengthy delay just as the grid operator is being forced to curtail large volumes of excess clean electricity.
WoodMac tips Australia to fall short of 82% renewables goal
Wood Mackenzie predicts Australia will fall well short of its target of 82% renewable generation by 2030 due to grid connection delays, inadequate investment, and moves from some state governments to scale back their clean energy ambitions.
Canadian Solar fund reports April shortfall amid Japan curtailments
Canadian Solar Infrastructure Fund says April output fell 10.2% below forecast across its Japan portfolio due to increased grid curtailments, especially on the island of Kyushu.
Net electricity prices for end customers fall below zero for first time in Germany
As PV and wind power plants caused a significant oversupply on May 11, the electricity price fell to a low of minus €250 per megawatt-hour. Charging PV storage systems or electric cars during these hours thus generated income for customers with dynamic electricity tariffs between 12 pm and 3 pm.
Flexibility options are a central concept for highly renewable energy systems research
To address the variability of renewable energy for a stable supply, 22 distinct types of flexibility options are found in 100% renewable energy systems research articles, categorized into power-to-X, energy storage, demand response, transmission and distribution grids, and curtailment.
Cow poop (and more) on the floor at Intersolar
Cow dung battery binder, a beautiful electric moped, parking lot level car charging, big rig charging, and “balcony solar” energy storage on the floor at Europe’s largest solar power show.
‘Blaming renewables for Spain’s blackout is like faulting the thermometer for the fever’
The recent blackout in the Iberian grid should not be interpreted as failure of renewables. But it did provide Europe with a sign the energy system is changing, shedding light on the necessity to govern 21st-century technologies with 21st-century control systems.
PV outperforms wind, piezoelectric energy in street lighting
Scientists in Thailand have assessed which technology between PV, wind, or piezoelectric energy is better for powering street lighting and have found solar is the winning tech, as it proved both economically and technologically feasible.
IPS unveils 8.1 MWh utility-scale BESS
IPS has developed an 8.1 MWh utility-scale battery energy storage system (BESS) housed in a 20-foot container with an integrated 4 MW inverter. The Bulgarian manufacturer says it aims to meet growing demand for efficient, large-scale energy storage solutions.
How to integrate solar-plus-storage with heat pumps
Scientists in Spain have simulated a system that uses both power-to-heat-to-power thermal batteries and lithium-ion batteries for energy storage. The hybrid system reportedly achieved a 7% lower LCOE compared to a PV system relying solely on lithium batteries, while simultaneously increasing PV self-consumption by up to 20%.
