   en.wikipedia.org/wiki/Emergency_power_system

   A backup generator for a large apartment building A backup power fuel cell for telecom applications A portable emergency power generator in a shipping container. An emergency power system is an independent source of electrical power that supports important electrical systems on loss of normal power supply.

4. Standby generator - Wikipedia

   en.wikipedia.org/wiki/Standby_generator

   Standby generators. A standby generator is a back-up electrical system that operates automatically. [1] Within seconds of a utility outage an automatic transfer switch senses the power loss, commands the generator to start and then transfers the electrical load to the generator. The standby generator begins supplying power to the circuits. [2]

5. Stand-alone power system - Wikipedia

   An inverter is used to generate AC low voltage, which more typical appliances can be used with. A typical stand-alone solar PV system at a sewage treatment plant in Santuari de Lluc , Spain Stand-alone photovoltaic power systems are independent of the utility grid and may use solar panels only or may be used in conjunction with a diesel ...

6. Cost of electricity by source - Wikipedia

   en.wikipedia.org/wiki/Cost_of_electricity_by_source

   The levelized cost of electricity (LCOE) is a metric that attempts to compare the costs of different methods of electricity generation consistently. Though LCOE is often presented as the minimum constant price at which electricity must be sold to break even over the lifetime of the project, such a cost analysis requires assumptions about the value of various non-financial costs (environmental ...

7. Smart grid - Wikipedia

   en.wikipedia.org/wiki/Smart_grid

   Using mathematical prediction algorithms it is possible to predict how many standby generators need to be used, to reach a certain failure rate. In the traditional grid, the failure rate can only be reduced at the cost of more standby generators. In a smart grid, the load reduction by even a small portion of the clients may eliminate the problem.
