DEREGISTRATION OF SECURITIES

This Post-Effective Amendment No. 1 (the “Post-Effective Amendment”) relates to the registration statement on Form S-8 (File No. 333-167196 ) (the “Registration Statement”), which was filed with the Securities and Exchange Commission by China Hydroelectric Corporation, a company established under the laws of the Cayman Islands (the “Registrant”), and became effective on May 28, 2010. Under the Registration Statement, a total of 12,000,000 ordinary shares of the Registrant, par value $0.001 per share (the “Ordinary Shares”) were registered for issuance upon exercise of options granted or to be granted pursuant to the Registrant’s 2008 Share Incentive Plan (the “Plan”). This Post-Effective Amendment is being filed for the sole purpose of deregistering any unissued securities previously registered under the Registration Statement and issuable under the Plan.

On January 13, 2014, the Registrant entered into an agreement and plan of merger (the “Merger Agreement”) with CPT Wyndham Holdings Ltd. (“Parent”) and CPT Wyndham Sub Ltd. (“Merger Sub”), a wholly owned subsidiary of Parent. On July 3, 2014, at an extraordinary general meeting, the shareholders of the Registrant voted to adopt the Merger Agreement and the transactions contemplated thereby, as contemplated by the Merger Agreement.

On July 9, 2014 (the “Effective Time”), pursuant to the Merger Agreement, Merger Sub was merged with and into the Registrant (the “Merger”), with the Registrant continuing as the surviving corporation and a wholly owned subsidiary of Parent. Upon the completion of the Merger, all outstanding Ordinary Shares and American depositary shares of the Registrant and all outstanding and unexercised options to purchase Ordinary Shares pursuant to the Plan were cancelled.

As a result of the Merger, the Registrant has terminated all offerings of its securities pursuant to the Registration Statement. The Registrant hereby removes from registration, by means of this Post-Effective Amendment, any and all of the securities registered under the Registration Statement which remain unsold as of the Effective Time.
