White House ratepayer pledge lists Bitdeer and sets five rules for data-centre power costs
Bitdeer appears among data-centre signatories to the White House Ratepayer Protection Pledge. The framework says large facilities should procure added supply, pay delivery upgrades and special rates, invest locally and support resilience. It is a public commitment, not a substitute for tariffs or permits.
Energy Economics study models a Bitcoin “productivity trap” for efficiency gains
An open-access Energy Economics paper argues that more efficient mining hardware can expand equilibrium resource use without increasing Bitcoin output. Its model also finds that surplus renewables may cut emissions while increasing hardware turnover, and evaluates a global Pigouvian tax as a policy response.
Canaan brings an 8 MW hash-to-heat case and Avalon home miners to BTCHEL
Canaan says a Nordic district-heating project using Avalon A1566HA miners is operating at 8 MW, while its BTCHEL stand will feature Nano 3S, Mini 3 and AvalonQ home systems. We separate the published specifications from the questions operators still need to verify.
EU report maps data-centre efficiency and prepares common standards
The European Commission reviews the first EU reporting cycle for data centres, quantifies gaps in the evidence and sets out a rating scheme, simpler reporting and possible minimum performance standards.
IEA sets out a digital toolkit to use existing power grids better
A new IEA report explains how monitoring, control systems, grid-enhancing technologies and carefully governed AI can increase the safe use of transmission and distribution networks.
UNECE roadmap puts crypto mining inside large-load grid planning
UNECE calls for strategic integration of data centres, AI facilities, electrolyzers and cryptocurrency mines through conditional connections, fair tariffs, flexibility and transparent data.
Cuentas signs a staged 24 MW West Texas mining power agreement
A September 23 SEC filing describes up to ten 2.4 MW container sets and about 4,200 ASIC miners, with $0.05/kWh energy pricing, revenue share and an 80% take-or-pay floor.
PNNL releases RATLLE method for large-load oscillation risk
PNNL-39459 presents a three-stage workflow for screening, simulation and severity analysis. Case studies show modeled 50 MW cyclic loads can excite wide-area grid modes at resonance.
PNNL models data-center controls as grid-service resources
PNNL report PNNL-39553 models coordinated compute, cooling, battery and onsite generation controls on a modified IEEE 24-bus system. The results are simulations, not operating guarantees.
DOE selects 21 geothermal projects as mining power demand grows
Five selected projects will test enhanced geothermal systems and 16 will drill for resource data. Up to $99 million is contemplated for initial work, but selections are not funding awards or new power for miners.
NERC computational-load standards pass initial ballot
NERC says foundational reliability standards for data centers, AI clusters and cryptocurrency facilities passed an initial ballot. Results still require validation and the standards process continues.
DOE emergency order expands Carolinas grid options during late heat
The September 18–21 order lets Duke Energy Carolinas dispatch specified and backup resources when reliability is threatened. We explain what it means—and does not mean—for flexible mining loads.
