Barnsley will compete in the Npower Championship next season after the energy giants struck a deal with the Football League to replace Coca-Cola who has sponsored the three divisions for the last six seasons.
The deal, worth £21m, will last for three years and outgoing Football League chairman Lord Mawhinney said:
"Npower is a widely respected company with a strong pedigree in sports sponsorship".
"Their support is a huge boost to our clubs and represents the enhanced reputation of the Football League in the commercial marketplace."
