National Grid

Solar and wind generation supplied a record 80% of power demand on Australia's national electricity grid, according to a report by The Guardian. The milestone marks a new high for renewable penetration on the network and highlights the pace of Australia's shift away from coal and gas. Commenters online are sharing the figure as evidence that renewables can cover the bulk of demand, with debate continuing over grid stability and backup capacity.

Australia's main electricity grid has recorded 80% renewable energy across consecutive days, with rooftop solar at times supplying more than half of demand. The milestone highlights how quickly household solar and other renewables are displacing coal and gas generation in the national market, drawing attention as one of the fastest energy transitions among advanced economies.

Australia connected a record 9.1GW of renewables and storage capacity to its National Electricity Market, while the pipeline of proposed projects reached 75.4GW. The figures point to accelerating large-scale clean energy build-out across the country's power grid.

Uganda and South Sudan have launched an electricity interconnection linking their national power grids, according to APAnews. The link is intended to let Uganda export power to South Sudan, where access to reliable electricity remains limited after years of conflict. The project is part of wider regional efforts to integrate East African energy markets.

Ukraine's national grid operator Ukrenergo says no restrictions on electricity consumption are planned for Monday, September 28, meaning households and businesses should face no scheduled power outages. The announcement is being shared across Ukrainian news feeds, with readers watching grid updates closely as the country continues to manage electricity supply under wartime conditions.

Deployable Energy has achieved first criticality at Idaho National Laboratory, a key milestone indicating its reactor system successfully sustained a nuclear chain reaction during testing. The American Nuclear Society highlighted the achievement, drawing attention from nuclear industry watchers who see it as a step toward compact, transportable nuclear power for remote sites, defense applications, and off-grid energy needs.

Ukraine's national grid operator Ukrenergo says no restrictions on electricity consumption or scheduled blackouts are planned for Friday, 2 October. The operator expects the power system to cover demand that day. The announcement offers reassurance to Ukrainians who have faced repeated outages amid damage to energy infrastructure, and is being shared as part of routine daily updates on the country's electricity supply situation.

California's governor has signed a fusion energy bill into law, a move framed as strengthening the state's leadership in the global race to develop fusion power. The legislation positions California as a hub for fusion research and commercialization as governments and private companies compete to bring the technology to the grid. Details on the bill's specific provisions and funding levels have not been reported.

Ukraine's Ministry of Energy and the United Nations Development Programme have launched the Ukraine Energy Installation Facility, a joint initiative aimed at speeding up the recovery of the country's damaged energy infrastructure and strengthening its resilience. The facility is expected to support restoration work as Ukraine continues to face strikes on its power grid, with international partners backing reconstruction efforts.

National Grid carbon intensity has fallen to 166gCO2/kWh, a low level compared with the last 24 hours, prompting a call for households to run energy-hungry appliances like washing machines now. Real-time grid intensity tracking is increasingly used to help people cut emissions by timing electricity use to moments when the UK power mix is cleanest.
