Headlines and what they mean

Apply for the Heat Network Efficiency Scheme (HNES): Round 13

The Department for Energy Security and Net Zero (DESNZ) has launched Round 13 of the Heat Network Efficiency Scheme, offering up to £30 million in grants for projects that improve heat‑network efficiency. Commercial buyers can apply to secure funding for district‑heating upgrades, potentially reducing heat‑fuel spend and supporting decarbonisation targets. source

Gas system in transition: security of supply

DESNZ’s consultation on the gas system’s transition highlights concerns over supply security as the UK moves away from fossil‑based generation. It invites industry comment on infrastructure resilience, storage needs and the role of imported gas, signalling that future gas contracts may incorporate tighter security clauses. source

Capacity Market: Hydrogen to Power and interconnectors

A call for evidence seeks stakeholder views on incorporating hydrogen generation and new interconnector capacity into the Capacity Market. Early engagement suggests a pathway for hydrogen‑fired plants to earn capacity payments, offering an alternative to traditional gas peakers for large‑scale users. source

Energy Trends: UK renewables

DESNZ’s latest renewables statistics show wind now accounts for 23.1% of generation and biomass 10.2%, with overall renewable output continuing its upward trajectory. The data underlines the growing reliability of clean generation, useful for firms modelling long‑term power procurement. source

Electricity bill discount scheme for transmission network infrastructure

The proposed discount scheme aims to reduce transmission‑network charges for eligible projects, potentially lowering the ancillary cost component of electricity bills. Companies with capital‑intensive transmission upgrades should monitor eligibility criteria as the scheme is refined. source

Warm Homes Loan Scheme: apply to participate as a lender (Phase 1)

Phase 1 of the Warm Homes Loan Scheme invites lenders to fund energy‑efficiency improvements for qualifying households. While targeted at residential customers, the scheme may free up private‑sector capital that could be redirected to commercial retrofits. source

Geopolitics and global markets

Global oil markets remain tight, with distillate stocks sinking and US diesel reserves near 23‑year lows, fuelling a diesel price surge that can ripple into UK transport fuel costs source source. Shipping routes through the Strait of Hormuz stay under scrutiny as a 4‑million‑bpd “shadow oil highway” operates and VLCCs resume movements after a pause, adding geopolitical risk premiums to crude pricing source source. Meanwhile, the United States is on track for record natural‑gas production in 2026 and has increased waterborne shipments from the Gulf Coast, bolstering global LNG supply and tempering European gas price spikes source source.
