Grids & Integration

The Department of Mineral Resources and Energy (DMRE) of South Africa has opened the third bid window for its Battery Energy Storage IPP Procurement Programme (BESIPPPP), which is procuring a total of 1,744 MW of four-hour battery storage systems. It has also announced the final winner from the first window.

Official figures from Sweden’s energy association says more solar was added than estimates suggested during a record year for PV deployment in 2023, with the country’s cumulative capacity now standing at around 4 GW.

Researchers in Indonesia have investigated how shading effects may influence the performance ratio of a PV system. Their analysis also considered payback period and return on investment.

Polish grid operator Polskie Sieci Elektroenergetyczne (PSE) has announced its third disconnection of renewable energy capacity this year. This time it has initiated the reduction of 1,201 MW to 1,877 MW of PV in response to oversupply.

High interest rates, inflation, and customer uncertainty could slow down residential PV growth in Sweden this year, despite record solar installations in 2023, but interest in utility-scale PV remains strong.

Researchers in the U.S. have repurposed a commonplace chemical used in water treatment facilities to develop an all-liquid, iron-based redox flow battery for large-scale energy storage. Their lab-scale battery exhibited strong cycling stability over one thousand consecutive charging cycles, while maintaining 98.7% of its original capacity.

German municipal utility Westfalen Weser is looking to develop a 120 MW/280 MWh battery storage facility at the site of a former nuclear power plant in the German state of North Rhine-Westphalia.

UK-based Konexa has finalized a deal that will see Climate Fund Managers and Microsoft’s Climate Innovation Fund invest $18 million to establish Nigeria’s inaugural private renewable trading platform and provide renewable energy to Nigeria Breweries.

German startup Domum has developed PV charging-parking systems for e-scooters and e-bikes. They use up to 660 W of solar panels.

ETIP PV explains how the energy system integration of PV should transition towards a smart and digitalized system, supported firstly by digitalized PV manufacturing and system and secondly by intelligent distribution control.
