Electrical Infrastructure Upgrade to Support SALIX Works

The SALIX 3C works involve the removal of the existing gas boilers within the boiler house and the supply, installation, and commissioning of two new electric boilers, each rated at 252kW. The site's existing electrical capacity is insufficient to support these works. An upgrade to the electrical infrastructure is therefore required to meet the additional demand and maintain headroom.

The electrical upgrade includes the following:

The current on-site transformer is rated at 0.8MVA. It is proposed that this be replaced with a new 1.5MVA transformer to support the increased demand. Transformer to include a feeder pillar for distribution of new LV supplies and to meet DNO requirements.

This upgrade will maintain the existing headroom to contribute towards future EV charging (requirements not known at this time).

Works are to include for the excavation, laying of ducts, cables, backfilling, and reinstatement of the cable route between the transformer and the plant room.

New cable containment will be required at both ends of the proposed duct route.

All works are to be completed in accordance with relevant standards, regulations, and site.

Requirements, including Testing of the HV and LV electrical installation and co-ordination of works with Humberside Police Joint Estate Service Engineers and the DNO.
