What does Agreement mean? In competition law practice, an agreement is any form of coordination between undertakings that shows a meeting of minds about market conduct (for example pricing, output, customers or territories). It is not limited to a legally enforceable contract: it includes informal or “gentlemen’s” understandings, oral arrangements, email exchanges and tacit understandings, and extends to decisions of associations of undertakings. Mere parallel conduct is insufficient without evidence of contact or communication. The term is used in legislation and developed by case law: Article 101 TFEU, section 4 of Ireland’s Competition Act 2002, and the UK Chapter I prohibition in the Competition...

What is a power purchase Agreement?

A power purchase agreement (PPA) is a Contract between an electricity producer (generator) and the buyer of that electricity (offtaker) that sets out the commercial Terms governing the sale and purchase of power from a generation project. For our comprehensive suite of resources and precedents on power purchase, see: Power purchase agreements and routes to market—overview. A PPA offers a route to market for electricity produced by the generator and, for renewable generating stations, any green benefits the generator receives for producing electricity from renewable sources, which may be sold on to electricity suppliers. It is the agreement under which a significant share (if not all) of a project’s revenues are earned and, as a result, the PPA supports the economics of most power projects. Most PPAs include provisions addressing the following matters:

  • commencement and term
  • sale of power
  • sale and transfer of any green benefits (for projects generating electricity from renewable sources)
  • credit for embedded benefits (where the plant is connected to a distribution network)
  • connection and metering arrangements
  • forecasting, maintenance and outages

These clauses are standard across PPAs and frame how projects sell power and related benefits to the market in practice...

This Practice Note This Practice Note reviews mechanisms used in settling litigation. A Tomlin order consists of a consent order paired with a schedule. It operates to stay proceedings on terms that have been agreed. The provisions contained in the schedule may remain confidential. This Practice Note describes the scope of confidentiality attaching to the schedule and sets out how it differs from a standard consent order. Sample wording for a Tomlin order is included, alongside links to precedents, as well as guidance on court approval. It also addresses varying, setting aside and enforcing a Tomlin order, including the considerations the court will take into account when handling applications for each. Further guidance is provided on interpreting and applying the relevant provisions of the CPR; however, some courts and divisions impose very specific requirements for both drafting and approval, and for approaching the schedule and confidentiality issues. Accordingly, you must consider the particular rules and court guide provisions in the forum where your claim is proceeding when drawing up the Tomlin order...
