Paul Vaughan, RFU Business Operations Director, said: "We are delighted to have secured such a major commercial name as EDF Energy to be the sponsor for five competitions covering premier to grassroots rugby.
"EDF Energy is closely involved with rugby already as the EDF Group is an Official Global Partner of Rugby World Cup 2007 and, in France, EDF is also a major partner of the French professional league (LNR). We are looking forward to a productive relationship over the next three years."
Vincent de Rivaz, Chief Executive of EDF Energy said: "Our partnership with the RFU and Premier Rugby will help us build on the brand awareness generated by our successful sponsorship of the ITV World Cup coverage. It also enables a connection with almost 2,000 amateur rugby clubs which are at the heart of their communities. For us this grass roots dimension is a vital part of developing our business and the relationship we want to have with our customers, our employees and the communities in which we live and work.
"EDF has a long relationship with rugby in France and I am delighted to extend this to the UK. We are all passionate about sport and with our new partners we will work hard to help ensure rugby continues to be a force for good in England and Wales as well as the source of great pleasure for all who play and watch it."
Jon Varney, Commercial Director of Premier Rugby Ltd, added: "The tournament was a great success last season, with over a quarter of a million people watching the matches live, and we are excited to have EDF Energy as the new sponsor.
"Attendances at the group stage showed a twelve per cent increase on the previous year and this season many of our clubs have added the matches to their season tickets, so I would expect another marked increase. Add to that number the millions who will watch the matches live on BBC Television and S4C and you have a fantastic tournament.
"When we start the group stage in September there will be no shortage of clubs desperately keen to win the EDF Energy Cup."
EDF Energy was represented in this deal by its Head of Brand, Louise Poole, and Keith Impey, CEO of Sponsorship Media. Three rounds of matches will be played in the four-team group stages at club grounds before a double header semi-final at a venue to be confirmed on March 24th 2007 and the final at Twickenham on Sunday April 15th.
London Wasps will kick off their Cup defence at Cardiff Blues - a team they beat 40-19 in the pool stages at the Causeway Stadium last October.
Wasps and the Blues are again in Group B along with London Irish and Saracens, while newly-promoted NEC Harlequins take over from relegated Leeds Tykes in Group C.
The BBC will televise at least three matches from the group stages on network, plus both semis and the final, with further group matches being shown live on BBC Wales and S4C.
Terry Burwell, Tournament Director, said: "The inaugural competition was a great advert for the game as showed by the live crowds and television audiences and we are looking forward to three successful years with EDF Energy.
"The groups have been kept the same to aid teams geographically and so they can benefit from home games against clubs they had to travel to last year.
"The semi-final double header at the Millennium Stadium, followed by the final at Twickenham, were two fantastic occasions and I'm sure that this season will be equally successful."
WRU Chief Executive Steven Lewis said: "Last season's inaugural tournament brought some hugely competitive and enthralling rugby to our club and regional grounds and television screens.
"It was great to see the Scarlets representing the Welsh Regions at the semi-finals and final of the competition. The challenge for us now is to be even more competitive and for more Welsh regions to be challenging for the EDF Energy Cup."
