Guyana launches net billing scheme for rooftop PV
Guyana has introduced a net billing program for rooftop PV systems up to 100 kW and for larger systems based on a customer’s maximum demand. It aims to expand distributed generation and reduce grid dependency.
Brazilian energy storage hampered by technical challenges, lack of regulation
While Brazil wastes billions of real on curtailment, the electricity sector is demanding urgent action on an energy storage capacity reserve auction which is now not expected until 2026. ‘What is missing is the courage to unlock the market,’ said Greener CEO Marcio Takata.

At least 18 GW of batteries await Brazil’s planned auction
While Brazil is making progress in customer-side, “behind-the-meter” and off-grid battery solutions – with more than 700 MWh – it still lacks guidelines for a planned gigawatt-scale national auction. Markus Vlasits, president of the Brazilian Association of Energy Storage Solutions (ABSAE), tells pv magazine about the nation’s utility-scale battery bottleneck.
The Hydrogen Stream: UK researching hydrogen storage nodes
Ofgem has awarded GBP 500,000 ($677,000) to a consortium led by National Gas and Gravitricity to develop a lined shaft system for storing up to 100 tons of green hydrogen underground. The six-month project aims to assess feasibility ahead of a potential demonstration in 2026.
High-frequency monitoring of floating PV
Researchers in Brazil have installed a vertical thermistor chain with six temperature loggers beneath a floating PV plant and at a nearby reference site. The system also recorded dissolved oxygen and photosynthetically active radiation to assess environmental impacts.
Panama to include storage in energy auctions
In an exclusive interview with pv magazine, Panamanian Energy Secretary Juan Manuel Urriola said the government will open the electricity market to private investment and revise regulations to enable energy storage.
