The Provision of Operations and Maintenance Services for the London Borough of Haringey's Decentralised Energy Network (DEN) Programme

The DEN portfolio is anticipated to grow substantially during the next decade and so key features of the Procurement are:

• the ability to add new networks and/or network extensions and interconnections into the Contract(s);
• the ability of the chosen Service Provider to undertake design reviews and adoptions.

There are 3 key areas where the Service Provider will be required to deliver operationally:

• Planned and Preventative Maintenance - this underpins the Contract and must be delivered in accordance with agreed frequencies.
• Optimising the level of energy performance required from the DEN as set out in the Output Specification and in terms of, for example:

(a) delivery temperatures;

(b) proportion of heat from low or zero carbon source;

(c) boiler efficiency.

(d) Seasonal Coefficient of Performance for heat pumps.

A comprehensive suite of Service Levels as defined in Schedule 9 of the draft Contract and which cover, for example:

(a) responses to system failures;

(b) restoration of heat supplies;

(c) implementation of a disaster recovery plan

The network is composed of four Authority-led neighbourhood scale DEN Systems situated at:

• Broadwater Farm - an existing group heating scheme serving 1970s Council blocks. A major works project to expand and refurbish the system is completing in early 2021. The network now serves c850 occupied dwellings and 2 schools from a recently refurbished central boiler house and plans to grow to 1,200 dwellings;
• Tottenham Hale - this is a new build scheme with a back up and top up boiler house connecting circa 12 development sites in the next decade which incorporate c.2,100 homes. These development sites will be supplied via either bulk supply or adoption of secondary networks to allow direct supply to final customers;
• Wood Green - this is a new build scheme with back up and top up boiler house connecting circa 6 development sites in the next decade with a mix of bulk supply and adoption of secondary networks. These development sites include around 2,200 homes and will be supplied via either bulk supply or adoption of secondary networks to allow direct supply to final customers;
• North Tottenham - the core scheme is a new build single site with 2,500 homes with full adoption of secondary networks and back up and top up boiler house. It is expected to grow to serve around 10 neighbouring sites with a mix of bulk supply and adoption of secondary networks;

Area Network - the DEN portfolio will progressively construct sections of an area wide heating network taking LZC heat from Energetik to the four energy centres above. The Authority also plans to extend the area wide network southwards to supply bulk heat to third party developments at St Ann's hospital and Woodberry Down (in Hackney). This would result in 13+km of network.

The wider portfolio including the energy centres, neighbourhood scale networks served from these hubs, private developments served and borough-wide network interconnecting to Energetik's Meridian Water network is also expected to be developed over the contract period and progressively added to the scope of the Contract.
