CORRECTING MOTOR POWER FACTOR CAN IMPROVE EFFICIENCY, INCREASE DISTRIBUTION CAPACITY AND EXTEND EQUI
The imperative in industry to cut energy costs and reduce green house gases is good news for suppliers of high efficiency motors. However, the projected efficiency gains from using EFF1 or 2 type machines will not be achieved if motor system and supply problems that existed before they were installed are not resolved. One of the most common of these is low power factor. Motors operated with low power factors are expensive and inefficient. In the worst cases this can result in utility supply companies having to increase their generation and transmission capacity to handle the reactive power component caused by inductive loads. There is a price for this: in the UK, the threshold value for power factor is 0.85, below this figure industrial users are generally charged more by their suppliers.

UK manufacturer Midland-ACS, has developed a control system capable of operating in the harsh environment of gas turbine heat recovery systems destined for the Al Shaheen oil field in Qatar. 
Energy costs have doubled over the past two years for many organisations, straining budgets and questioning viability
Current solid oxide fuel cell systems (SOFCs) produce a typical power range of 1-5kW, far from sufficient to meet the multi-megawatt demands placed on a commercial power plant.
