Climate change is now a global problem and the UK Government is introducing various measures to reduce energy consumption.
To encourage the efficient use of electricity, Variable Speed Drives (VSDs) that are used for certain applications will be eligible for an Energy Capital Allowance covering the cost of their supply and installation.
VSDs have to be purchased from the list of qualifying products and only drives used for gas or liquid movement applications with pumps, fans or compressors are eligible.

Radical new approach to motion control?
While traditional motion control systems typically have their own proprietary text based programming languages, ControlLogix uses standard 'ladder logic' programming.
The scheme will be funded from revenue generated from the impending Climate Change Levy.
Traditional methods for controlling the flow of gases and liquids include by-pass systems, outlet dampers or inlet vanes and all these systems have very poor energy efficiencies.
For example, using an outlet damper to reduce the flow to 80% requires nearly 90% energy input; the comparable figure using an inlet vane is 80% energy input.
Compare this with a VSD where the same 80% flow requires an energy input of only 50%.
If the output flow is reduced to 60% the input energy requirement is just over 20%.
Many applications run at flow rates of less than 100% and it can be seen that installing a VSD provides considerable energy savings.
An added incentive to install an Allen-Bradley VSD is that the cost of energy is due to rise from April 1st 2001, with the introduction by the UK Government of the Climate Change Levy.
This Levy applies to all commercial and industrial users of energy and covers electricity, coal, natural gas and LPG.
The levy on electricity is the highest at 0.43 p/kWh, which can represent a 10 to 20% increase in energy bills.
Allen-Bradley VSDs represent an opportunity to reduce energy consumption, and eligible installations will attract up to 100% contribution from the Government's capital allowance fund.
VSDs are reliable in use and provide considerable flexibility, including the opportunity for the remote control of machines via communication networks.
In addition to the supply of individual components for energy saving, Rockwell Automation has developed a comprehensive suite of products, software and engineering services to manage and reduce energy consumption.
These range from the PowerMonitor and Line Synchronisation Modules, through Rockwell Software including RSEnergy and RSPower energy management suites, to turnkey engineering services for complete production facilities.
Delivering this range of services is the Power and Energy Management Solutions (PEMS) group, based at its centre in Bletchley.
PEMS consultants work with the customer to re-engineer their processes to yield the biggest return on investment.
