Electricity import and export

Electricity import and export: supply to circa 4,400 MPANs, flexible purchasing and price-fixing services, PPA sleeving, export route to market and settlement

Options: The contract term for every lot runs from that lot's commencement date to 31 March 2032, with extension options of 3 years and then a further 2 years, exercisable at DCC's sole discretion. Options are exercisable per lot and independently. Where exercised, expiry moves from 31 March 2032 to 31 March 2035 and then to 31 March 2037. Supplier fixed fees are held firm for the initial period and are reviewed on exercise of an extension option only by cumulative CPI over that period. DCC may also purchase additional volumes and services within the scope of each lot as its estate changes, including supply to new or altered supply points and metering services at additional or replacement meters. For Lot 4 (Metering services), DCC may agree an earlier commencement date for defined improvement activities ahead of 1 April 2027, and the half-hourly data collection and aggregation element phases into the Lot 4 contract from April 2028.

Renewal: The contract may be extended at DCC's sole discretion by 3 years (to 31 March 2035) and then by a further 2 years (to 31 March 2037). Each extension option is exercisable separately, and options are exercised per lot and independently of any other lot. DCC is not obliged to exercise any option. Supplier fixed fees are held firm for the initial period and are reviewed on exercise of an extension option only by cumulative CPI over that period. Extensions would be used where continuing the arrangements represents value for money and supports service continuity across DCC's energy estate.

Gas import: non-domestic gas supply of circa 67.8 GWh per annum to DCC's gas supply points, including purchasing and price-fixing services against DCC instructions, and all industry arrangements required to deliver supply.

Gas export: purchase and offtake of biomethane injected by DCC into the gas distribution network (gas-to-grid), circa 45.8 GWh per annum and circa 447 GWh over the maximum contract term. Under this lot the Supplier purchases biomethane from DCC as principal for onward sale into the gas market, so consideration flows from the Supplier to DCC rather than from DCC to the Supplier. The Supplier's remuneration may arise through management or transaction fees, trading margins or spreads, deductions, retained amounts or other elements of the sale-price methodology, to be established through this competition. The estimated value stated for this lot is the gross market value of the biomethane expected to be transacted, stated inclusive of VAT at the currently applicable 20% rate; it is not an estimate of the Supplier's remuneration and does not represent expenditure by DCC, and DCC gives no warranty as to future volumes or market prices. Commencement 1 July 2027; initial period to 31 March 2032, with extension options of 3 years and then a further 2 years exercisable at DCC's sole discretion.
