Energy Act 2004 meaning

Published by a LexisNexis Energy expert
What does Energy Act 2004 mean?
In practice, Energy Act 2004 refers to the UK statute that sets the legal framework for civil nuclear decommissioning and several wider energy regulatory matters.

Key features include: - Establishment of the Nuclear Decommissioning Authority (nda) with statutory functions to secure the decommissioning and clean‑up of the UK’s civil nuclear legacy, manage designated nuclear sites and related radioactive waste liabilities, and contract with site licence companies.

UK competition law: DMCCA water mergers consequential amendments; CMA sports broadcasting investigation; SAU hydrogen CCUS review; Supreme Court refusals (Cérélia, DAF); NSI order on Harbour Energy/BASF—31 July 2024

Mergers Government publishes The Digital Markets, Competition and Consumers Act 2024 (Water Mergers) (Consequential Amendments) Regulation 2024 The Digital Markets, Competition and Consumers Act 2024 (Water Mergers) (Consequential Amendments) Regulation 2024 (the Regulations) (SI 2024/840) have been issued, accompanied by an explanatory memorandum. These Regulations deliver technical updates to the Water Mergers (Modification of Enactments) Regulations 2004 (SI 2004/3202) (the 2004 Regulations), prompted by Royal Assent to the Digital Markets, Competition and Consumers Act 2024 (DMCCA). The aim is to prevent the 2004 Regulations from cross-referring to wording in the Enterprise Act 2002 that has since been removed or no longer matches the current text. Under the Water Industry Act 1991, Part 3 of the Enterprise Act 2002—containing the principal statutory framework governing mergers—applies to mergers between water and sewerage businesses in England and Wales, subject to the modifications specified in the 2004 Regulations. The new Regulations revise those modifications so that they align with the amendments to Part 3 of the Enterprise Act made by Schedule 6...

The TCC reviewed established authorities confirming that damages are available in procurement challenges only where the contracting authority’s breach is “sufficiently serious”, a test grounded in EU law. The issue was recently examined in Braceurself v NHS England, where the TCC held that the “sufficiently serious” assessment...

UK Data Centres as Critical National Infrastructure: Legal Framework, Regulatory Oversight, NIS Regulations 2018 Duties and Expected Cyber Security and Resilience Bill Reforms

What is the CNI regime? Critical National Infrastructure (CNI) encompasses the physical and digital assets, sites, and networks that keep a nation running, underpinning the health, safety, security, and economic prosperity of its people. In the UK, the basis for CNI rests on a mix of long-standing government programmes, statutory duties, and policy directives intended to protect pivotal industries. Together, they support the functioning of the country and the well-being of its population. Collectively, these elements are indispensable to national operations and the welfare of citizens. The regime arose from the imperative to shield vital services and infrastructure central to national security, economic resilience, and public protection—a subject under review by many states from the mid-twentieth century. That imperative sharpened towards the close of the twentieth century as threats from terrorism, espionage, and cyberattacks intensified. Practical momentum followed with bodies such as the National Security Advice Centre (NSAC) and the National Infrastructure Security Co-ordination Centre (NISCC), created in the 1990s and early 2000s to deliver specialist guidance...
