An online calculator has been launched to help small and medium-sized enterprises (SMEs) find the most competitive energy supplier.

Launched by UKPower.co.uk, the new tool will help managers of SMEs to compare the pricing structures of a number of suppliers, while an online form will allow the user to complete the switching process online, reports bCentral.

"Switching online is the quickest and easiest way to ensure you're not paying over the odds for energy and is a must for companies that are diligent with expenditure," said Graham Self, director of UKPower.

Using information collected from suppliers, UKPower enables the comparison of suppliers for gas, electricity and dual fuel.

In related news, RWE npower has unveiled plans to develop a new gas-driven power station, expected to become operational by 2009.
