Data Centre Demand

What should state policymakers do about data centers?

This episode analyzes the rapid growth of data center electricity demand, noting that 15 states accounted for 80% of US demand in 2023. A single hyperscale campus can consume 15% to 20% of a utility's capacity, while building the necessary transmission takes 5 to 15 years.

Why it matters — Highlights the severe operational mismatch between the rapid deployment of hyperscale computing facilities and the 5-to-15-year timeline required to build supporting transmission infrastructure.

Nuclear

Climate Change Is Rewriting Europe’s Nuclear Cooling Assumptions

Romanian engineers used 180 kg of explosives to clear a rock outcrop in the Danube's Bala Canal. The blast allowed the construction of a temporary dam to maintain cooling water levels for a nuclear plant during low river flows caused by extreme heat.

Why it matters — Highlights how climate-induced low river levels force extreme, invasive civil engineering interventions to prevent thermal power plant shutdowns.

Grid & Transmission

Factcheck: How nuclear, gas, wind and solar power are affected during heatwaves

This analysis examines how extreme heatwaves exceeding 40°C in Europe during June and July 2026 impacted different power sources. The extreme temperatures forced nuclear shutdowns due to cooling limits, reduced gas plant efficiency, dropped wind speeds, and caused electricity networks to sag.

Why it matters — Quantifies the simultaneous derating of multiple generation types during extreme heat, forcing grid operators to plan for correlated capacity drops across nuclear, thermal, and wind.

PJM’s big new data center plan: Make the states figure it out

PJM Interconnection has introduced a plan shifting the responsibility of managing data center load growth onto individual states and utilities. The policy aims to prevent soaring grid upgrade costs from being socialized across all utility customers in its 13-state territory.

Why it matters — Establishes a regulatory precedent where regional transmission organizations refuse to socialize the grid upgrade costs of large digital loads, shifting the financial burden directly to local utilities and states.

Storage

World’s Largest 12.8 GWh Battery Storage Cluster Activated in China

Envision Group has integrated an AI management system into its 12.8 GWh battery storage network in northern China. The network includes a 4 GWh flagship plant that went online in February 2026.

Why it matters — Demonstrates that coordinating gigawatt-hour scale storage networks requires transitioning from localized controls to centralized, AI-driven management systems.

How to bring a geothermal well back from the dead

Geothermal developer Zanskar acquired a failing power plant in New Mexico in 2024 to rehabilitate it. The plant's shallow wells had been rapidly losing heat, causing a steep decline in power output.

Why it matters — Focuses on the engineering challenge of thermal drawdown in shallow geothermal reservoirs and the technical viability of rehabilitating underperforming assets.

Grid cybersecurity: how big is the threat & what should we do about it?

An interview with cybersecurity expert Patrick Miller explores the realistic threats to the US bulk power system. The discussion covers the actual impact of Chinese inverter vulnerabilities, federal enforcement rules, and why physical threats like squirrels still cause more frequent damage than hackers.

Why it matters — Provides a realistic threat model for grid operators, distinguishing between sensationalized nation-state cyber threats and the actual, more frequent causes of physical grid disruption.

Data Centre Demand

Data Centers Strain Grids, Prompt Moratoriums

Global electricity demand from data centers grew 17% in 2025, with AI-focused centers up 50%, leading to significant grid strain. In Q1 2026, 75 U.S. data center projects worth $130 billion were blocked or delayed due to energy constraints and delayed grid connections. New York imposed a one-year moratorium on new data center construction in mid-July, and PJM accepted 715 new generation projects (over 200 GW) into its reformed interconnection process to address supply shortages.

Why it matters — Grid operators and developers must now factor in significant regulatory and financial risks, including potential moratoriums and higher costs for grid upgrades, when planning new data center projects.

Nuclear

Multiple Advanced Reactors Achieve Criticality

Oklo's Groves Isotope Test Reactor achieved criticality on August 6, 2026, in Lockhart, Texas, becoming the fifth DOE-authorized advanced reactor to reach this milestone this summer. This follows Antares Nuclear's Mark-0 (June 4), Valar Atomics' Ward 250 (June 18), Deployable Energy's Unity (June 30), and Aalo Atomics' Aalo-X (July 4) also achieving criticality, as reported in an August 4, 2026, DOE fact sheet.

Why it matters — These milestones demonstrate the successful, safe operation of new nuclear reactor designs, accelerating the pathway to commercial deployment and contributing to grid decarbonization.
