II.2.1)Total quantity or scope:
The proposal is to design and construct up to 2 new Energy Centres and a heat network to supply heat in the form of Low Temperature Hot Water (LTHW) to a core portfolio of 5 communally heated residential blocks (the core scheme, 454 homes). The heat network would connect the existing Bunhill Heat and Power pipe network to the new Energy Centres and to the connecting buildings via thermal substations located in the communal boiler rooms of the buildings to be connected.
The extended scheme will add a CHP engine to one of the energy centres and supply an additional three communally heated residential blocks (an increase of 215 dwellings, revised total 669 homes), a school, sheltered housing block, a community centre and nursery. This extended scheme also has the possibility of connecting a further 13 private and council developments along the network route.
A Pre planning application has been submitted by Islington Council for a new Energy Centre to be installed on the site at the junction of Central Street and Moreland Street.
The tender may include the following elements:
A) An above ground energy centre with enclosure and containerised equipment, subject to planning approval.
The principal elements of the above ground Energy Centre are likely to include:
1. 550-1.1 MWth ammonia heat pump
2. Thermal storage
3. Duty/Standby pumps with inverter control
4. Thermal dump
5. Control system
6. LV intake with import/export metering
7. LV switchgear
The extended scheme would include a185kWe – 1MWe CHP at this above ground energy centre.
B) A below ground energy centre, formed by constructing an enclosure in an existing accessible below ground void.
The principal elements of the below ground Energy Centre are likely to include:
1. 350 MWth ammonia heat pump
2. Thermal storage
3. Duty/Standby pumps with inverter control
4. Control system
5. LV intake with import metering
6. LV switchgear
C) Thermal Hydraulic sub-stations within the boiler rooms of each of the connecting buildings providing plate heat exchanger interface between the buildings’ existing secondary heating systems and the new district heat network.
D) Approximately 600 m length of new underground district heat network (pipework diameter ranging from 80 mm to 300 mm) and fibre optic network, both with additional network capacity to facilitate possible future growth of the network and/or interconnection with other networks.
E) Maintenance contracts covering the balance of the Energy Centre equipment, network and customer connections.
The length of the construction element will be approximately 12 months. Following construction there will be a period of 12 months of performance monitoring, which will include seasonal commissioning.
There will be an output based maintenance contract associated with this contract. Full details will be provided in the ITT.
Indicative combined construction contract value of the core scheme is GBP 3 000 000 – GBP 3 500 000.
Indicative combined construction contract value of the extended scheme (excluding optional additional connections) is GBP 4 900 000 – GBP 5 400 000.
These works are anticipated to exclude works on our partners (LUL and UKPN) equipment and critical infrastructure.
Estimated value excluding VAT:
Range: between 3 000 000 and 5 400 000 GBP
