Grids & Integration

Scientists have completed a one-year trial of a model that calculates solar irradiation forecasts up to 24 hours in advance. Singapore’s Energy Market Authority now plans to adopt solar irradiance forecasting, as the model has an average error rate below 10% for one-hour forecasts.

Carrier will soon begin field tests for a prototype air-source heat pump for cold climates. It is designed to provide high-efficiency heating performance in harsh climates with temperatures equal or below negative 29 degrees Celsius, while being grid-interactive. The US-based heating tech specialist expects to commercialize the solution by 2024.

Aspen Creek Digital, a US bitcoin miner, has started operations at a 30 MW bitcoin data center powered by an 87 MW solar park in Texas. The project is the company’s second solar-powered bitcoin-mining center.

PG&E has secured approval to set up a vehicle-to-grid (V2G) export compensation mechanism for commercial EV charging customers in California. Sono Motors is debuting its Sion solar electric vehicles in the US market, while Toyota and Jera are installing innovative second-life battery systems in Japan.

While near neighbors, the electricity generation of the countries of Southeast Asia couldn’t be further apart. Indonesia burns locally mined coal; Malaysia has reserves of oil and gas; and populous Singapore, Vietnam, and the Philippines depend on fossil fuel imports. They could all benefit from increased solar electricity but higher grid capacities and interconnection are key for an opportunity to unlock the power of the sun.

Construction has started on a 350 MW/1.4 GWh compressed air energy storage project in Shangdong, China.

As part of Aurora Solar’s Empower 2022 online solar summit, Bernadette Del Chiaro, from the California Solar & Storage Association, will moderate a talk about electric utilities and how they have abused their monopoly position to discriminate against solar in the US. Here, she gives pv magazine a taste of the presentation.

Alfanar has revealed plans to set up a solar project including ground-mounted and floating PV to provide power to the Al Jubail 2 water desalination plant on the east coast of Saudi Arabia. It will require an investment of SAR 1.2 billion ($319 million).

Banks Group’s latest announcement underscores the fact that the UK battery storage market has one of the world’s fastest-growing project pipelines.

US researchers have unveiled a new way to speed up EV charging, while researchers in China have created a three-dimensional composite lithium anode to improve battery safety and efficiency.
