Grids & Integration

San Miguel, which is now behind on its original plan to deliver a 1 GW/1 GWh fleet of battery energy storage systems (BESS) by the end of 2022, continues to roll out big batteries across 32 sites in the Philippines, in order to integrate up to 5 GW of renewables into the island nation’s grid.

Storage specialist Fluence has launched Ultrastack, a battery energy storage system (BESS) for storage-as-transmission assets (SATA). It is designed to help network owners and operators to manage renewables curtailment, increase the use of power lines, and limit congestion.

While it initially had a chilling effect on the Polish residential solar market, the transition from net metering to net billing has also resulted in positive changes, such as better sizing of rooftop PV systems and a higher rate of self-consumption, says Instytut Energetyki Odnawialnej (IEO), a Polish research body.

The minigrid space continues to attract a lot of attention from development partners in Africa. Minigrids can actually generate profits, so there is no doubt that commercial finance players will eventually jump on the bandwagon, according to the Africa Solar Industry Association (AFSIA).

Swiss researchers have looked at whether storage could be cheaper than curtailment in medium-voltage distribution networks with significant amounts of PV capacity. They considered storage costs, operational costs, grid constraints, electricity costs, PV generation models, and loads.

Phaesun and Solar Cooling Engineering have developed a PV-powered cold room for small-scale farmers in Africa. The solution, which has been installed at a farm in Kenya, includes a 2.8 kW solar array and vapor compression heat pumps.

Iberdrola is using a springer spaniel in a solar park to smell electrical problems that could lead to power cuts. It is also using a robotic dog to detect and analyze faults in substations.

Kenya’s government plans to build 137 solar minigrids across remote locations in the East African country. The project received $150 million in funding from the World Bank.

RIC Energy has built a 1.3 MW PV array and a 4.5 MWh battery system for two water treatment plants and five water pumping stations in Malawi. The hybrid system will treat enough water to supply more than 200,000 people.

Sterlite Power’s Lakadia-Vadodara transmission project will deliver more than 5 GW of electricity from the Indian state of Gujarat to the rest of the country.
