MADRID (Reuters) -Spanish renewable energy firm Ecoener plans to raise about 200 million euros ($237 million) through a stock market listing to fund the expansion of its wind farms, solar parks and hydroelectric plants.

It joins a roster of Spanish energy groups aiming to capitalise on investor demand for environmentally-friendly assets, boosted by international targets to reduce economic reliance on carbon and stem climate change.

Ecoener, which manages projects with a combined capacity of 141 megawatts (MW), said on Wednesday it will submit a prospectus to Spain’s market regulator, a first step towards a listing, but did not say when it planned to sell shares.

Founded in 1988, Ecoener has a further 142 MW in construction and 1.5 GW in planned future developments across 11 countries. Half its installed capacity is wind, 37% hydroelectric and the rest solar.

Sun-kissed Spain, which aims to add 60GW in new renewable capacity this decade, is home to companies with a track record for developing clean power internationally, including Acciona, which plans to list a stake in its own energy unit.

Energy group Repsol is also considering offering a stake in a new low-carbon unit on the public market. An industry source said rival Eni could make a similar move in nearby Italy.

Expectations of a glut of deals of this kind, combined with a recent drop in stock market valuations for renewable energy companies, prompted fellow IPO candidate Capital Energy to bow out of the race this week.

Ecoener, which is currently fully owned by founder and chairman Luis de Valdivia, has hired Societe Generale as global coordinator to help take it public.

Banco Sabadell, Caixabank, Credit Agricole and HSBC will act as joint bookrunners, while Banco Cooperativo Espanol will be co-lead manager on the proposed listing.
