The island's council voted against plans to put turbines on Cheverton Down
The firm hoping to build three giant wind turbines on the Isle of Wight has said it is planning to appeal against a decision to block the scheme.
The island's council voted in December against the bid by Cornwall Light and Power (CLP) to put the 125m (410ft) structures on Cheverton Down.
Campaign group The Wight Against Rural Turbines (Thwart) said the turbines would be a blight on the landscape.
CLP said the turbine plan could provide enough power for more than 4,700 homes.
The firm also pointed to backing from The Eco Island Supporters Group.
Steve Allen, development manager at CLP, said: "We've taken time to consider all the comments made throughout the planning process and we remain convinced that the development of a wind farm at Cheverton Down would be would be beneficial to the Isle of Wight.
"Firstly, the considerable wind resource available at this particular site would enable wind turbines to generate a significant amount of energy, therefore playing a major role in supporting the Isle of Wight's own renewable energy strategy.
"Secondly, the use of the Cheverton Down turbines for research and development purposes would send a clear message that the Isle of Wight wants to remain a centre for renewable energy."
A spokesperson for The Eco Island Supporters Group, added: "We are hoping that central government will make the decisions that our local council planning committee seems unable to."
In 2003, permission was granted for three smaller 52m (171ft) turbines on Cheverton Down.
