English solar developers prep for New Zealand
Hive Energy, Ethical Power Group and Solar South West have set up a joint venture they hope will lead to 350 MW of utility scale installations in a country which does not suffer from grid congestion and which appears to have an energy transition-friendly administration.
‘The chance to reset with a green recovery has now been lost’
Norwegian consultancy DNV today published the latest of its annual surveys of the state of the energy transition and lamented the fact so very little has been achieved during the last five years. We are forging ahead into a world that will be 2.3C hotter this century, predicts the report.
Cheapest long-duration storage for systems with high renewables
National Renewable Energy Laboratory researchers have studied which tech offers the lowest levelized cost of energy to provide the US Western Interconnection grid with electricity when wind and solar are not available. They assumed 85% renewables penetration and determined that geologic hydrogen storage and natural gas combined-cycle plants with carbon capture storage are the cheapest options for 120-hour discharge applications.
Combining big floating solar with hydropower
Scientists in Bangladesh have evaluated how a 50 MW floating PV plant could be integrated with the 230 MW Karnafuli Hydroelectric Power Station, located at the Kaptai Dam on the Karnaphuli River. They found that the two energy sources can be perfectly optimized and that PV can compensate for the reservoir’s shortage of water storage during the winter season while hydropower can compensate for the poor yields of the floating array during the monsoon season.
Synchronous condensers to lift constraints on renewables in South Australia
South Australia has shown how to rapidly transition to renewable energy generation, but cracks have appeared in its system. ElectraNet has deployed synchronous condensers to smooth out the gaps and keep the state grid running reliably.
Cutting Europe‘s energy costs through interconnection
A new study from Stanford University professor Mark Jacobson models energy grids powered by 100% wind, water and sunlight across Western Europe. The study finds that in such a scenario, increased interconnection between countries would lead to lower energy costs and better grid stability, as well as a hedge against sudden loss of supply due to extreme weather or other events.
Bidders plan to use ‘brown power’ to balance intermittency of solar in Singapore’s clean power tender
Solar developer NEFIN and electric company Tuas Power have tabled a joint bid to secure the rights to supply 100 MWh of ‘zero-carbon electricity’ from Malaysia to Singapore and said they initially intend to use “brown power” to secure supply during non-solar-generation hours.
UK power generation in 2020: Renewables up to 43%
Solar contributed 28% of the U.K.’s total renewable energy generation, which was dominated by wind power. The proportion of fossil fuels in the energy mix fell to a record low last year, at 37.7%.
Maxeon secures EU cash to make its ‘stick-on’ solar panels in France
The TotalEnergies-controlled solar manufacturer will secure an, as yet undetermined chunk of a new €118.6 million low-carbon innovation fund to start producing its frameless, glass-free solar roofing products at Porcelette, in northeastern France.
Hitachi ABB Power Grids commissions ultra-high-voltage DC link connecting Indian states
From pv magazine India. Hitachi ABB Power Grids in India today announced it has successfully commissioned one of India’s longest ultra-high voltage direct current (UHVDC) transmission links for Power Grid Corporation of India Limited. The ±800 kV, 6GW link can meet the electricity needs of more than 80 million people. It stretches 1,800-kilometers to connect […]
