(Adds details)

LONDON, Sept 30 (Reuters) - Clipper Windpower Plc CWPR.L said on Wednesday it was in talks with potential investors that could lead to a "significant investment" in the company.

The talks, with a number of "industrial multinationals and financial investors", could result in a new partner taking anything from a substantial minority position, investing at or around the current market price, to a full takeover, Clipper said in a statement.

"These competitive discussions are at an advanced stage and it is anticipated that an investment could be announced and completed before the company's financial year end," the company said.

Clipper Chief Executive Doug Pertz said the potential partners offer synergies and the "appropriate support to enhance Clipper's position" as it looks to take advantage of expected growth in the U.S. and offshore wind markets.

In a separate statement, Clipper posted a narrower first-half pretax loss of $120.2 million, compared with the previous year's $211.7 million, on revenue of $357.3 million.

The company said it sees full-year revenue at around $750 million, from the sale and delivery of around 260 turbines, although the deferred delivery of 130 turbines will hit margins by around $94 million. (Reporting by Simon Jessop; Editing by Hans Peters)
