China completes testing of 700 MW compressed air energy storage plant in Jiangsu
By Eve
China has finished full system commissioning tests on two generation units in the second phase of the Jintan compressed air energy storage facility in Changzhou, Jiangsu province, bringing total capacity to 700 MW. The plant stores energy by compressing air to over 130 atmospheres in four underground salt caverns at roughly 1,000 metres depth, with a combined volume of approximately 1.2 million cubic metres, then releases the air through turbines to generate electricity when needed. The facility now moves to grid connection trials and final commissioning, following project approval in December 2024.
Why it matters
Large scale energy storage infrastructure like this 700 MW CAES plant supports grid stability for variable renewables, indirectly enabling higher EV adoption by smoothing electricity supply for charging networks. Procurement teams tracking grid resilience projects can benchmark storage capacity and deployment timelines in markets with high renewable penetration.

750 affordable homes in UK now heated by mine water geothermal network
A new energy centre at Seaham Garden Village in the UK is now supplying low carbon heat to around 750 affordable homes using naturally warm mine water pumped from a Durham treatment facility. Energy Live News reported that the network has completed commissioning and is fully operational. The system uses geothermal processes that keep mine water at a relatively constant temperature year round, providing a dependable heat source instead of traditional heating fuel.
Why it matters
The operational mine water heating network demonstrates a replicable model for decarbonising heat in social housing developments, potentially informing procurement specifications for low carbon heating infrastructure at scale. The proven reliability of geothermal mine water as a consistent year round heat source may influence future district heating tenders and public sector energy resilience planning.
Tesla Powerwall autonomously grid-charged before peak rates to offset low solar yield in Arizona
A Tesla Powerwall owner in Tucson, Arizona, reported that the battery began charging from the grid at around 2:30 p.m. on a rainy day, ahead of a 3 to 7 p.m. peak rate window, after solar generation fell short. The homeowner had set the system to Saving mode and disabled Stormwatch, allowing the Powerwall to draw enough grid power to cover the high cost period. The case, shared on Reddit's r/Powerwall forum, illustrates how residential storage can automatically balance low renewable output with time of use tariffs.
Why it matters
The example shows demand side flexibility in action, with home batteries responding to tariff signals and weather conditions without manual intervention. For CPOs and utilities, it underscores the growing role of behind the meter storage in load shifting and the need for rate structures that reward or integrate such behaviour at scale.
Wound Type Current Transformer Market Forecast to 2035 Highlights EV Charging Infrastructure as Key Growth Driver
IndexBox's latest global market report identifies wound type current transformers as entering a decade of structurally higher demand through 2035, driven by electricity system digitalization, decarbonization and decentralization. Growth will be anchored in utility smart meter rollouts, renewable energy integration, EV charging infrastructure and industrial automation. The market is bifurcating between standardized catalog parts for high volume OEMs and customized, application engineered solutions for critical infrastructure.
Why it matters
For CPOs and charging network developers, the report signals that precision current measurement components essential for revenue grade metering and power quality monitoring in EV charging stations will see sustained supply and innovation through 2035. The bifurcation between standardized and custom solutions suggests procurement teams should assess whether catalog parts meet accuracy requirements or if critical sites warrant engineered transformer specifications.
