DAM meaning

Published by a LexisNexis Energy expert
What does DAM mean?
Day-Ahead Market (DAM) describes the organised wholesale electricity auction held one day before physical delivery, where generators, suppliers and traders submit bids and offers for each settlement period of the following day. A matching algorithm produces a uniform clearing price per interval (typically half-hourly), creating a widely used reference price. “DAM” is an industry term rather than a statutory definition. Its detailed meaning appears in market rulebooks and codes (for example, NEMO/exchange rules such as EPEX SPOT or Nord Pool, the SEM Trading and Settlement Code) and in contracts. Key legal uses include pricing and indexation in PPAs and route-to-market agreements, baseline pricing in electricity CfDs (via the applicable market reference price), collateral and margining under trading documentation, and quantifying losses or mitigation in disputes and termination scenarios. Jurisdictional position: - Great Britain (England & Wales and Scotland): DAM auctions are operated by NEMOs (including EPEX SPOT and Nord Pool). Following Brexit, GB is not part of the EU Single Day-Ahead Coupling; interconnector capacity is commonly allocated separately. - Ireland and Northern Ireland: the Single Electricity Market (I-SEM) includes an EU-coupled DAM operated via designated NEMOs under the SEM Trading and Settlement Code. Usage of “DAM” is broadly consistent across the UK...

BHP appeal: can funding Brazilian anti‑suit injunctive relief to restrain English proceedings amount to criminal contempt? Court of Appeal (England and Wales) hearing

Andrew Scott KC of Blackstone Chambers, counsel for BHP Andrew Scott KC said the planned appeal poses the issue of whether seeking anti‑suit relief in a foreign court, linked to proceedings in England, could amount to criminal contempt. Scott told the Court of Appeal that no English authority indicates that it could. BHP has lodged an appeal against a decision by Judge Adam Constable. In June 2025, sitting in the High Court, he held that BHP must confront allegations that it attempted to impede the municipalities’ access to justice in England by supporting proceedings in Brazil’s highest court that might frustrate compensation claims. The municipalities argue that BHP is in contempt of court for agreeing to finance a claim initiated by Ibram, a Brazilian mining association, before the South American country’s Federal Supreme Court in 2024...

Criminal disclosure review backs incremental change: early disclosure hearings, stronger judicial case management and AI pilots amid SFO software issues, mass digital evidence and recent case collapses

Released on 24 April 2024, the initial review authored by Jonathan Fisher KC of Red Lion Chambers identifies where the seasoned silk thinks progress could be achieved in updating a disclosure regime designed nearly three decades ago. Fisher believes that engaging the defence and the prosecution at an earlier stage could deliver huge gains, and he expresses confidence about the potential of artificial intelligence (AI). Yet he cautions that, in sprawling, data-rich matters, no flawless answer is available. Importantly, Zoe Osborne of Steptoe International (UK) LLP observed that the exercise does not seem to press for sweeping reforms to the framework, changes that would require Parliamentary sign-off and would probably face fierce opposition. Instead, she remarked, piecemeal adjustments to what already exists are required. That, Osborne suggested, might amount to a squandered opportunity to confront the root problems and resolve them, opting instead to patch a handful of cracks in an already leaking dam at this stage...

Structuring and Financing Hydropower Projects: Types, Construction and Hydrology Risks, Environmental and Social Due Diligence, PPAs, Lender Requirements and Market Trends

Overview Rain that falls, along with other forms of water, is intercepted as it travels through the hydrological cycle and put to work to produce electricity for consumption. This can be realised in a number of distinct ways, for example by tapping a river’s inherent force as it drops from upland terrain down to sea level across distance and gradient, or by building a dam and reservoir; in both arrangements, purpose-built, appropriately installed turbines and generators serve as the means of converting energy into power. Because water is not a finite global commodity and is not consumed while energy is produced as it moves downstream, hydropower is classed as renewable energy. Owing to fluctuations in seasonal flows, water availability, and landscape and geography by specific location, however, hydropower can be difficult to rely on as dependable baseload supply for the grid, and more often augments other national renewable generation as a ‘top-up’, providing additional supply into the grid when those sources, due to intermittency, fall short of prevailing demand...

All-Island Single Electricity Market (Republic of Ireland and Northern Ireland): post-Brexit legal and regulatory overview, market structure, codes, participants, interconnectors and trading (DAM/IDM/Balancing, capacity, FTRs, CfDs)

Brexit impact At 11 pm (GMT) on 31 December 2020, the transition/implementation period that followed the UK’s exit from the EU drew to a close. This moment—known in UK law as ‘IP completion day’—brought key transitional measures to an end and triggered major shifts across the UK’s legal framework. Any alterations pertinent to this content will be detailed below. From IP completion day, the European Union (Withdrawal) Act 2018 (EU(W)A 2018) established a fresh class of domestic UK law—retained EU Law (REUL)—comprising EU-derived rights and instruments that were kept in force in the UK after Brexit. On 29 June 2023, the Retained EU Law (Revocation and Reform) Act 2023 (REUL(RR)A 2023) received Royal Assent. REUL(RR)A 2023 reshapes how REUL is handled by: revoking large tranches of REUL from 31 December 2023 re-labelling REUL as ‘assimilated law’ from 1 January 2024 creating new powers concerning assimilated law This reclassification of REUL (and related expressions) as assimilated law signifies a shift...
