Grids & Integration

UK energy regulator green-lights transmission network operator budgets for five-year period. Initial budget of GBP 10.3 billion ($13.7 billion) approved with an upper-bound estimate of GBP 70 billion transmission investment by 2031. At least GBP 44 billion of transmission spend has already been committed, according to the regulator.

The Southern Johor Renewable Energy Corridor (SJREC) forms part of a $6 billion project developing a 2,000 kilometer-squared hybrid solar and battery energy storage system zone set to connect South East Asia.

Huawei’s FusionSolar 9.0 is a new integrated solar-plus-storage platform featuring smart inverters, AI-driven management, and grid-forming capabilities to turn solar plants into active grid-support assets. It boosts efficiency, reduces costs, and enhances stability in weak grids with high renewable penetration, according to the company.

Australian researchers developed a high-resolution energy modeling framework to assess how PV and batteries can supply 24/7 electricity to heavy industries, considering cost, grid interaction, and load flexibility. They found that, while technology cost reductions help, smart grid integration and flexible industrial operations are far more effective in lowering electricity costs and enabling 100% renewable energy use.

Morocco is seeking pre-qualified bidders for a 1,000 km ultra-high-voltage alternating current line to transmit about 2 GW between Boujdour and Tensift, with applications due Jan. 15, 2026.

Scientists in China have proposed a novel scheduling framework for microgrids based on hybrid PV and a small modular nuclear reactors. The framework uses multi-objective distributionally robust optimization with a real-time reinforcement learning mechanism and is reportedly able to reduce operational costs by 18.7%.

Scientists in China have developed an optimized energy management strategy for a wind-PV hybrid heat pump system that uses both thermal and electric energy storage. Using different seasonal interaction management strategies, they simulated four operational cases.

Scientists in India have developed a novel method to optimize the placement of an EV charging station on the grid, along with the size of its PV generation and battery storage. They have also created a framework for an innovative slot offering.

Scientists in the United Kingdom have compiled a new database of adiabatic compressed air energy storage projects. Using this data, they were able to determine the experience rate and identify the conditions under which the technology would be economically viable. According to their findings, costs have declined at a 15% learning rate since 2013.

Sunnic Lighthouse says Germany’s first prequalified solar project for secondary control reserve shows how quickly PV assets can move into advanced grid-services markets.
