The committee shows the particular technologies in this way because for the current state of technology development it will be less costly to have the grid-based electricity used with wind-based electricity, and for the possible future technologies it would be less costly to have an entirely wind-based system without the use of electricity from the grid.

The wodd s total capacity of grid-coimected electric power derived from wave energy is less than half a megawatt, distributed among several demonstration plants. The largest unit, the 350-kWe Tapered Channel plant in Norway, uses the hydropower approach. The plant was developed by Norwave AS and has operated continuously since 1986. Based on this durabiUty, two commercial orders were placed from other parts of the wodd. 

Even in developed countries with established grids, the notion of bio-based electricity generation is gaining some momentum outside the obvious cost benefits to co-fired plants. Examples include the recent establishment of powergenerating plants in Scotland and New England that are fuelled by chicken manure. 

Distributed plants start with a summary and design basis inputs (Tables E-33 and E-34), then natural gas (Tables E-35 and E-36) and grid-based electrolysis (Tables E-37 to E-39) Included under the latter is a combination of natural-gas-assisted steam electrolysis case, for future technology only. Wind and photovoltaics are shown for both stand-alone units (Tables E-40 to E-43) and in combination with the power grid (Tables E-44 to E-47). Tables E-48 and E-49 show the detailed buildup of the cost of electricity from photovoltaics, which is an input to the electrolysis calculations. 

The facility will be one of the largest biomass plants to be built in the world and is scheduled to enter commercial operation in late 2012. Young trees will be grown as a crop to produce wood chips. The plant will use 2.5 million tonnes of wood chips each year to produce 300 MW of electrical energy. The plant will operate 24 hours a day, all year round to meet some of the National Grid base load. 

Currently, most base stations are grid tied with the electricity grid providing prime power. Backup comes in the form of diesel generators, and to a much lesser extent some form of renewable - battery hybrid system. Off-grid base stations are much less common but when they are installed the norm is a two-diesel generator system, where one acts as the primary with the backup power provided by the other. 

With the establishment of an electrical grid, based on the advocacy of alternating current by Serbian American engineer and inventor Nikola Tesla (1856-1943), a vast assortment of analogue electrical devices were soon developed for consumer use, though initially these devices were no more than electric lights and electromechanical applications based on electric motors and generators.
