Generators and Backup Power

An outage history helps describe the problem but does not determine the answer alone. Identify what must remain supplied, what can stop and how long the interruption can be tolerated.

The work can include reviewing load requirements, assessing existing equipment, developing a connection and changeover scope, coordinating generator installation or replacement, and arranging maintenance and functional testing. Temporary provision needs its own connection, siting and removal plan.

The deliverables identify supported circuits, operating assumptions, the changeover arrangement and relevant inspection or test records. Fuel, exhaust, ventilation, access and controls are considered alongside electrical work. Where civil works, enclosures or associated services are needed, they form named parts of the package.

Selected loads or the whole property. Backing up selected circuits can be a different design from supporting every connected load. The assessment considers starting demand and the order in which equipment returns, not simply a total taken from equipment labels.

Generator or UPS. A generator-based arrangement has a starting and transfer sequence. Equipment that cannot tolerate that interruption may need a coordinated uninterruptible power supply. Compatibility must be assessed; Eaton explains generator and UPS interactions.

Manual or automatic operation. The choice affects controls, monitoring, the people needed on site and the test plan. These decisions must be explicit before equipment is selected.

Provide a list of equipment needing support, available demand information, electrical drawings and details of any existing generator, UPS or transfer equipment. Identify sensitive processes, required support time and acceptable interruption.

Site assessment also considers space, access for delivery and maintenance, fuel arrangements and the effect on neighbouring areas. Engine exhaust introduces a carbon-monoxide hazard; HSE addresses generator siting in its electrical safety guidance. Siting and connection require an appropriate technical design.

We establish the backed-up loads and site constraints, assess the supply and distribution interfaces, then define the equipment and works package. Connection requirements are checked with the relevant network party where applicable; the customer instruction does not authorise work on network-owned assets.

Installation or maintenance follows the agreed safe work and outage plan. Testing needs to demonstrate the relevant operating sequence and supported loads, rather than only that the engine starts. Handover includes the tested scope, operating information, maintenance requirements and any unresolved limitations.

Capacity, operating duration, noise treatment, fuel provision, delivery access, foundations, exhaust arrangements and cable routes affect cost. An existing connection point may reduce some work, but its suitability still needs assessment.

Plan time for design, equipment availability, any external permissions and coordinated testing. The interruption needed to connect and prove the arrangement must be agreed with those responsible for the affected equipment.

For industrial sites, distinguish essential controls from loads that can stop. For healthcare and care, the client's specialist continuity requirements define the design brief. In offices, IT needs may differ from general building loads.

These applications sit within the full sector range, including FM companies, public and community premises, leisure, construction, veterinary premises, energy and utilities, social housing, laboratories and secure estates. The complete service and project offering is available across the sectors we serve; the technical brief follows the particular site.

Our North East coverage includes Northumberland, Tyne and Wear, County Durham and the Tees Valley: Berwick-upon-Tweed, Alnwick, Morpeth, Hexham, Newcastle, Gateshead, Sunderland, Durham, Darlington, Hartlepool, Stockton-on-Tees and Middlesbrough, together with the areas in the full locations directory.

For a portfolio, provide each site's address and operating contacts so the programme can account for local access and dependencies.
