Dec 18 (Reuters) - Spanish renewable company Grenergy

has agreed to sell an asset portfolio in Chile to

ContourGlobal, a KKR company, for an enterprise value of

$962 million.

The transaction includes $50 million based on the achievement

of certain milestones and a debt of $643 million, Grenergy said

in a filing to the Spanish stock market regulator late on

Tuesday.

of nearly 11 gigawatt hours, and solar energy generation

projects with a potential capacity of 2 gigawatts.

The deal is expected to be completed in the coming days, the

company added.
