Contract requirements The Contract requires the Contractor to enter into a HV (High Voltage) COMER (Control, Operation, Maintenance, Emergency Response) agreement. Services to be provided under the COMER agreement are: • Assume full control of the various 11kV and 3.3kV systems at Altmouth and Crossens pumping stations for the duration of the contract via a formal transfer of control/operation from the EA to the Contractor. On transfer of control the Contractor can, subject to agreement, operate their own HV safety rules where these have been demonstrated to be equivalent or better than the Environment Agency’s. • Provision of high voltage Senior Authorised Person (SAP) services as well as competent personnel who have suitable qualifications, experience and authorisation to work on the HV systems specified. • Provision of a 24-hour 365-day emergency response service to enable attendance to site when a fault/defect requires urgent diagnosis/rectification. This includes the provision of HV Senior Authorised Person (SAP) services as well as competent personnel who have suitable qualifications, experience and authorisation to work on the HV systems specified. Ideally the Contractor should be able to attend site within 2 hours of receiving a call, however, longer response times may be considered. • Completion of two monthly, annual and 5-yearly planned preventative maintenance on all HV systems, and specific LV circuit breakers specified. This includes the provision a program of works for all PPMs. A list of PPMs will be provided as part of the tender. • Completion of remedial works on the HV systems specified as and when required. • Attendance to site to allow for isolations at HV to enable specialist contractors to undertake works or to enable safe access to HV areas. This includes liaison with the EA’s non HV maintenance contractor(s) and various EA teams as and when necessary. • Management of all documentation relating to the HV systems specified. Records will be audited periodically for compliance. • All Contractor personnel working on the Contract must be familiar with the sites specified. • Ensure that the EA’s pump attendants remain sufficiently trained and authorised in HV safety rules to be able to operate the Altmouth HV pumps starting procedure in hand via the onsite Scada system.
