Prime and Standby Power Generators

EcoPowerSupplies Generators provide critical power applications with a source of AC power. In Prime Power mode the generators continuously run and the mains may be present or simply used as a back-up source of power. In standby mode (the more traditional role), the generators provide power when the mains power supply fails. An uninterruptible power supply will be installed in critical IT applications with a battery sized to cover the generator start-up period.

At EcoPowerSupplies we supply generators as open-frame or enclosed sets. The canopies provide acoustic attenuation (to meet local authority planning guidelines) and a weather-proof enclosure (for outdoor installations). Generators can also be supplied as fully containerised systems including UPS systems, batteries, solar panels, cabling and LV switchgear for rapid deployment and/or remote installations.

Generator runtime is dependent upon the fuel-tank size the load. Fuel-tank size is typically a day-tank (8-hours) for a fixed installation, with options for 24-hour and 48-hour bunded tanks. EcoPowerSupplies also provides a refuelling and fuel management services. Sizing is dependent upon the critical power load, and in secondary applications the size and type of uninterruptible power supply installed – see our generator guide.

EcoPowerSupplies also provides a complete generator service package including site power surveys, installation, pipework and exhaust management, refuelling, maintenance contracts and 24-7 remote monitoring. Generator hire/rental sets are also available.

Some Key Factors To Consider When Specifying A Generator Set

  1. Power Requirements: the actual power requirements must be assessed and the generator suitably sized to support the load. Power may be expressed in both Apparent Power (kVA) and Real Power (kWe) terms. Generator sets are not Unity Power Factor rated and the most common power factor used is 0.8 meaning an 80kWe generator can provide 100kVA of apparent power. Load step is another important issue to consider as generators cannot always provide all their power output instantaneously. Load start-up currents should also be considered as these can be far in excess of normal running currents.
  2. Performance Characteristics: electronic and electrical equipment can be sensitive to their electrical supplies with a defined input voltage and frequency window and harmonic content. Generators have defined performance classes given in ISO 8528 Part 1 and must be matched to the load profile and its characteristics.
  3. Rating Required: generator sets have engines that are rated differently depending on whether the set is to be used continuously as a Continuous Operating Power (COP), Prime Rated Power (PRP) energy source or in a Standby back-up power mode which may be Limited Time Power (LTP) or Emergency Standby Power (ESP). The difference for these in engine rating may be up to 30%.
  4. Fuel To Be Used: a wide variety of fuels can be used including diesel, biodiesel, natural gas, LPG and others. Diesel is the most commonly used fuel. Biodiesel may be more environmentally friendly but can degrade over time.
  5. Ambient Environment: temperature and altitude affect generator performance. High temperatures and altitudes can limit power. Low temperatures can lead to starting issues.
  6. Autonomy Required: how long is the generating set expected to run for? This is known as its autonomy and is normally expressed in hours against a load percentage. The autonomy will influence the size of set chosen and fuel storage.
  7. Standards and Regulations: what standards does the generating set have to comply with? For use within the European Union the set will have to be CE marked. Other standards and regulations may apply relevant to the country of operating including safety, noise, pollution and emissions.
  8. Physical Environment: there are several inherent risks with a generator installation. If there is a risk of fire from the generator how will this be handled, especially if the generator is housed within a building? Building Regulations provide guidance and have to be complied with. Environmental risks also include leakage from fuel and coolants which must be managed. The Pollution Prevention Guidelines provide guidance on this matter. Generators also produce hot gases and fumes that will require external discharge to prevent risk to people or the environment. Generators can also be audibly noisy and an assessment should be made of the audible noise level allowed on the site. Fuel deliveries should also be planned for to accommodate refuelling requirements as well as storage of fuel on site.
  9. Electrical Interface: what is the voltage and frequency of the existing electrical infrastructure? Also consider the electrical protection of the generating set, loads to be supported and people who will use it. The right protective devices will have to be installed after determining the arrangements for Earthing, Neutral Earthing and to ensure the mains and generator cannot operate in parallel to supply a load without the appropriate switching and protective devices to allow this to occur.
  10. Grid Tied and Off-The-Grid Systems: attention will have to be given to G59 if the generator is to be used to supply back-up power into the grid to benefit from STOR feed-in-tariffs. As much care and attention also has to be given to generator sets used in Off-The-Grid self-sufficient installations.
  11. Bunding: all tanks over 200litres, in most circumstances, must be bunded
