ESP meaning

Published by a LexisNexis Energy expert
What does ESP mean?
In legal practice, ESP (Early Site Permit) refers to a US nuclear regulatory authorisation that pre‑approves the suitability of a site for a nuclear power station before any construction or operating licence is sought. It is a defined process under US federal regulation (10 CFR Part 52) administered by the US Nuclear Regulatory Commission (NRC). An ESP typically addresses site safety characteristics, environmental impact assessment and emergency planning arrangements, following public consultation. It does not itself permit construction; rather, it is intended to be referenced in a later combined licence or other downstream approvals. There is no direct UK or Irish equivalent. In England and Wales and in Scotland, broadly comparable stages involve development consent and environmental impact assessment under planning legislation, the Generic Design Assessment of reactor technology, and the grant of a nuclear site licence by the Office for Nuclear Regulation under the Nuclear Installations Act 1965. Northern Ireland follows UK planning frameworks; Ireland does not authorise nuclear generation. UK and Ireland practitioners most often encounter ESPs in cross‑border energy, project finance or M&A documentation, where ESP status informs due diligence, risk allocation, conditions precedent and long‑stop dates.

Compliance with the PSC Regime for Scottish Limited and Qualifying Partnerships: Identification, Companies House Reporting, Investigation, Ongoing Obligations and Protection Regime

People with significant control (PSC) regime The people with significant control (PSC) regime came into force on 6 April 2016. Its framework is contained in Part 21A of the Companies Act 2006 (CA 2006), as amended by the Small Business, Enterprise and Employment Act 2015 (ss 81–83, Sch 3). The regime tackles the opacity of corporate ownership, where historically only the legal holder of shares—and not always the beneficial owner—was recorded. Through the PSC register, companies and certain other entities must provide clearer, more up-to-date details of who ultimately owns or controls them. This information is publicly accessible on the central register at Companies House. It supports investors when assessing a potential investment and assists law enforcement agencies with money laundering investigations. For companies, the primary legislation is supplemented by The Register of People with Significant Control Regulations 2016, SI 2016/339 (the PSC Regulations), as amended by the Information about People with Significant Control (Amendment) Regulations 2017, SI 2017/693 (2017 Regulations). LLPs incorporated under the...
