This Amendment No. 1 (this “Amendment”) is filed to amend and supplement the Schedule 13D relating to the ordinary shares, par value $0.001 per share (“Ordinary Shares”) and American Depositary Shares, each representing three Ordinary Shares (“ADSs”), of China Hydroelectric Corporation (the “Company”), filed by the Reporting Persons named therein with the Securities and Exchange Commission (the “SEC”) on December 5, 2012 (the “Schedule 13D”). Except as specifically amended by this Amendment, the Schedule 13D remains in full force and effect. All capitalized terms contained herein but not otherwise defined shall have the meanings ascribed to such terms in the Schedule 13D.

Item 3. Source and Amount of Funds or Other Consideration.

Item 3 of the Schedule 13D is hereby supplemented as follows:

On July 3, 2013, CPI purchased from Vicis Capital Master Fund (“Vicis”): (i) 3,918,666 Ordinary Shares, (ii) an option (the “Option”) to acquire 34,959,893 Ordinary Shares (the “Option Shares”) from Vicis, and (iii) a warrant (the “Warrant”) to acquire up to 10,004,157 Ordinary Shares from the Company. The amount of funds used by CPI for this transaction was: (i) $3,000,000 to purchase the Ordinary Shares (or approximately $0.77 per Ordinary Share), (ii) $100 to purchase the Option, and (iii) $100 to purchase the Warrant. The source of funds for this transaction was NewQuest’s working capital.

Item 4. Purpose of Transaction.

Item 4 of the Schedule 13D is hereby supplemented as follows:

The Reporting Persons reserve the right to change their plans with respect to their investment in the Company at any time, as they deem appropriate, in light of their ongoing evaluation of (a) their business and liquidity objectives, (b) the Company’s financial condition, business, operations, competitive position, prospects and/or the trading price of the ADSs, (c) industry, economic and/or securities markets conditions, (d) alternative investment opportunities, and (e) other relevant factors. Without limiting the generality of the preceding sentence, the Reporting Persons reserve the right to at any time or from time to time (i) purchase or otherwise acquire additional securities (including Ordinary Shares and/or ADSs) of the Company, or instruments convertible into or exercisable for any such securities (collectively, “Company Securities”), in the open market, in privately negotiated transactions, by exercising the Option and the Warrant or otherwise, (ii) sell, transfer or otherwise dispose of Company Securities in public or private transactions, (iii) cause Company Securities to be distributed in kind to its investors, or (iv) encourage (including, without limitation, through communications with directors, management, and existing or prospective security holders, investors or lenders of the Company, existing or potential strategic partners, industry analysts and other investment and financing professionals) the Company to consider or explore (A) sales or acquisitions of assets or businesses or other extraordinary corporate transactions, including transactions in which the Reporting Persons and/or their affiliates may be proposed as acquirors, or (B) other changes to the Company’s business or structure.

If CPI exercises the Option in full, it would beneficially own a majority of the Outstanding Shares. The Reporting Persons have not made any decision as to whether the Option will be exercised, in whole or in part, and reserve all rights with respect to such decision.

The information set forth, or incorporated by reference, in Items 3 and 6 of this Amendment is hereby incorporated by reference in this Item 4.

Item 5. Interest in Securities of the Issuer.

Item 5 of the Schedule 13D is hereby amended and restated in its entirety as follows:

(a) CPI may be deemed to beneficially own an aggregate of 97,741,619 Ordinary Shares, or approximately 56.8% of the Ordinary Shares deemed outstanding, which consists of (i) 52,777,569 Ordinary Shares directly beneficially owned by CPI (which include 10,114,506 Ordinary Shares represented by 3,371,502 ADSs and 42,663,063 Ordinary Shares), or approximately 30.7% of the Ordinary Shares deemed outstanding, (ii) 34,959,893 Ordinary Shares, or approximately 20.3% of the Ordinary Shares deemed

outstanding, that CPI may be deemed to beneficially own under Rule 13d-3 pursuant to the terms of the Option Agreement (as defined below), and (iii) 10,004,157 Ordinary Shares, or approximately 5.8% of the Ordinary Shares deemed outstanding, that CPI may be deemed to beneficially own under Rule 13d-3 pursuant to the terms of the Warrant. NewQuest, its sole general partner, NewQuest GP, and NewQuest Management, an investment manager of NewQuest GP, may be deemed to beneficially own all of the Ordinary Shares (including Ordinary Shares represented by ADSs) beneficially owned by CPI. The foregoing calculations of percentage ownership are based on 172,061,324 Ordinary Shares deemed to be outstanding for purposes of this Amendment, which consists of 162,057,167 Ordinary Shares issued and outstanding as represented by the Company in its Annual Report on Form 20-F filed on April 18, 2013, as amended, and an additional 10,004,157 Ordinary Shares that may be issued by the Company to CPI upon exercise of the Warrant in full.
