AI Data Centres Need Big Batteries But Lithium Isn’t Fit-For-Purpose
The biggest constraint facing AI data centre expansion is storage and the unique way they use power, leading to unpredictability in drawing electricity from the grid. Traditional generation sources like coal and nuclear may still be necessary due to the volatile energy demand of AI data centres. Data centres require buffering capacity to reconcile intermittent supply with intermittent demand, with lithium-ion batteries degrading rapidly under constant cycling. Flow batteries offer a solution by allowing energy and power capacity to scale independently, enabling relentless cycling without degradation typical of lithium-ion systems. The world's renewable build-out is accelerating, but most large-scale batteries remain short-duration systems, highlighting the need for innovative storage solutions for AI-driven data centres. Investing in storage technologies designed for high-cycle operation can help harness renewable energy and prevent the reliance on fossil fuel backup, ultimately allowing AI data centers to contribute to a clean energy future.

ADB unveils $70bn plan for Asia’s energy and digital infrastructure
The Asian Development Bank (ADB) has launched a $70bn Pan-Asia Power Grid Initiative to enhance energy and digital infrastructure in Asia and the Pacific by 2035. The initiative aims to connect national and subregional power systems to facilitate the cross-border flow of renewable energy, integrating 20GW of renewable energy and reducing regional power sector emissions by 15%. ADB plans to raise $50bn by 2035 to develop extensive cross-border power infrastructure, prioritizing transmission, grid integration, and renewable energy projects. This initiative will also establish 22,000 circuit-kilometres of transmission lines, enhance energy access for 200 million people, create 840,000 jobs, and involve private sector co-financing alongside ADB's own resources.

Record battery output, big winds push monthly gas generation to lowest level in more than two decades
In April, Queensland led in wind, solar, and battery output, with a notable increase in wind energy generation. The state also achieved a record-breaking month for big batteries, with over 100 GWh discharged by utility-scale battery energy storage systems. Australian utility PV and wind assets collectively generated 4.7 TWh, marking a 24% increase from the previous year. Gas generation across the National Electricity Market decreased by 49%, showcasing the ongoing trend of batteries displacing gas during the evening peak.

Dominion to open nation’s biggest offshore wind farm next year
Dominion Energy's Coastal Virginia Offshore Wind project, the largest in the U.S., is moving forward with nine turbines already in the water and plans to have all 176 turbines operational by June 2027. Despite a temporary halt by the Trump administration, construction resumed in January, and the project's estimated cost was reduced to $11.4 billion after the Supreme Court struck down tariffs. Virginia ratepayers are expected to save $5 billion in fuel costs during the first decade of operations, highlighting the significant economic and environmental benefits of this renewable energy initiative.

Dominion upbeat on offshore wind as cost estimate eases, sales rise
Dominion Energy is prioritizing the completion of the Coastal Virginia Offshore Wind project, the largest wind farm in the US, by June 2027. The project is 75% complete with 9 out of 176 turbines installed, with an estimated capital budget of $11.4 billion and expected fuel savings of $5 billion over 10 years. Dominion's focus on transmission and distribution infrastructure, along with the growth in data center capacity, is driving significant regulated investment needs. Additionally, Dominion's Virginia territory will see an increase in gas generation, solar, and energy storage spending, with more opportunities for regulated capital deployment in the early 2030s. A new Virginia law requires Dominion to petition for 20 GW of energy storage projects by 2040, up from 3 GW by 2035, which will be reflected in the company's capital update next year.
