MAJOR AND CONNECTED TRANSACTION

ACQUISITION OF SINOSING POWER

●

On 29 April 2008, the Company entered into the Transfer Agreement with Huaneng Group, pursuant to which the Company agreed to acquire from Huaneng Group 100% interests in SinoSing Power. The consideration to be paid by the Company comprises (1) approximately US$985 million (approximately HK$7.674 billion) being the capital injected into SinoSing Power by Huaneng Group (including US$197 million (approximately HK$1.535 billion) from internal sources of Huaneng Group and US$788 million (approximately HK$6.139 billion) from a loan obtained by Huaneng Group); and (2) an aggregate amount of approximately RMB176 million (approximately HK$196 million), being all the related expenses (including loan interest) directly incurred by Huaneng Group in relation to the acquisition of 100% interests in Tuas Power through SinoSing Power from Temasek. On Closing Day, the Company shall pay the consideration in full, of which US$788 million shall be settled by way of assignment of debts while the remaining balance of approximately RMB1.572 billion (approximately HK$1.752 billion) shall be paid by way of cash in RMB. The purchase price was determined on arm’s length terms. Upon completion of the Acquisition, the Company will own 100% shareholding in SinoSing Power, together with the interests attached thereto as at 24 March 2008. SinoSing currently holds 100% interests in Tuas Power.

●

Huaneng Group directly holds 8.75% of the total issued share capital of the Company. In addition, it holds a 51.98% direct interest and a 5% indirect interest in HIPDC while HIPDC is the controlling shareholder of the Company. Therefore, Huaneng Group is a connected person to the Company. Under the Hong Kong Listing Rules, the Acquisition constitutes a connected transaction to the Company.

- 1 -

●	As the transaction scale of the Acquisition exceeds 2.5% of the applicable percentage ratios as calculated pursuant to Rule 14.07 of the Hong Kong Listing Rules, the Acquisition is therefore subject to the Independent Shareholders’ approval. In addition, the Acquisition also constitutes a major transaction to the Company which requires Shareholders’ approval.
●	The Company will convene an EGM for the purpose of seeking the approval from Independent Shareholders for the Acquisition (including the Transfer Agreement). According to the Hong Kong Listing Rules, Huaneng Group, HIPDC and their respective Associates will abstain from voting in respect of the resolution relating to the Acquisition.
●	The Company and the Independent Directors Committee have reviewed the Acquisition. The Company has also appointed DBS as the independent financial adviser to make recommendations to the Independent Directors Committee and the Independent Shareholders as to whether the terms of the Acquisition are fair and reasonable and whether the Acquisition is in the interests of the Company and its shareholders as a whole, and to advise the Independent Shareholders on how to vote. The Company expects the notice of the EGM and the circular giving further information on the Acquisition and containing the advice of DBS as well as the recommendations from the Independent Directors Committee to be despatched to shareholders within 21 days from the date of this announcement.

BACKGROUND

The Company and its subsidiaries develop, construct, operate and manage power plants in China nationwide, with a total generation capacity of 33,723MW on an equity basis. The Company wholly owns sixteen operating power plants, and has controlling interests in thirteen operating power companies and minority interests in four operating power companies. Currently, it is the largest listed power producer in China.

Huaneng Group is principally engaged in the operation and management of industrial investments; the development, investment, construction, operation and management of power plants; organising the generation and sale of power (and heat); and the development, investment, construction, production and sale of products in relation to information, transportation, new energy and environmental protection industries.

Huaneng Group is the controlling shareholder of HIPDC, holding a 51.98% direct interest in HIPDC. In addition, Huaneng Group also holds a 5% indirect interest in HIPDC and directly holds 8.75% of the total issued share capital of the Company. As at the date of this announcement, HIPDC holds approximately 42.03% of the total issued share capital of the Company.

- 2 -

The relationships among the Company, Huaneng Group and HIPDC are as follows:

*	Huaneng Group, through China Hua Neng Group Hong Kong Limited, its wholly-owned subsidiary, indirectly holds a 50% interest in Pro-Power Investment Limited while Pro-Power Investment Limited holds a 10% interest in HIPDC. Therefore, Huaneng Group holds a 5% indirect interest in HIPDC.

The transaction as contemplated by the Transfer Agreement constitutes a connected transaction to the Company. The transaction scale of the Acquisition in aggregate exceeds 2.5% of the applicable percentage ratios as calculated pursuant to Rule 14.07 of the Hong Kong Listing Rules, therefore the Acquisition is a connected transaction to the Company, which shall be subject to the Independent Shareholders’ approval according to Rule 14A.18 of the Hong Kong Listing Rules. Huaneng Group, HIPDC and their respective Associates will abstain from voting in the EGM in respect of the ordinary resolution to approve the Acquisition (including the Transfer Agreement).

The Acquisition also constitutes a major transaction to the Company, which would require the approval of the Shareholders.

REASONS FOR THE ACQUISITION AND THE CAPITAL INCREASE, AND PRICING FACTORS

The Acquisition reflects the Company´s continued implementation of its development strategy which focuses on both green-field development and acquisition. Tuas Power, which is 100% owned by SinoSing Power, is one of the three largest power companies in Singapore. It has advanced technologies and solid management and operations. Tuas Power has been regarded by the international power market as a quality asset. Upon completion of the Acquisition, the Company will own 100% interests in SinoSing Power, which in turn holds the entire equity interests in Tuas Power. This would help the Company to diversify its geographical risk and to improve its fuel structure. Through the operation of Tuas Power, the Company will participate in Singapore’s competitive power generation market and power retail market, thus gaining experience in operating in a competitive power market. In addition, the Acquisition provides the Company with a platform to expand overseas and to develop its experience in overseas investment operation, which is in line with the Company´s “Expand Outwards” strategy, and is to the long-term benefit of the Company and its shareholders.

The Company´s scale of operation will be further enhanced upon completion of the Acquisition. Its generation capacity will increase by 2,670 MW on an equity basis, while the total generation capacity on an equity basis will increase from 33,723 MW to 36,393 MW, representing an increase of 7.9%. The Company´s asset and liabilities will also be increased correspondingly with only a slight increment in the debt level, thereby further utilising the financial leverage effect. Upon completion of the Acquisition, Tuas Power, as a new source of profit for the Company, will help to increase the overall profit of the Company.

The consideration for the Acquisition was determined on the basis of normal commercial terms and arm´s length negotiation between the Company and Huaneng Group. The parties agreed that the consideration shall comprise (1) approximately US$985 million being the capital injected into SinoSing Power by Huaneng Group; and (2) all the related expenses (including loan interest) directly incurred by Huaneng Group in relation to the acquisition of 100% interests in Tuas Power through SinoSing Power from Temasek.

The consideration was based on the purchase price paid by Huaneng Group to Temesak in the acquisition of 100% issued shares in Tuas Power through SinoSing Power on 24 March 2008. Determination of the aforementioned purchase price was first based on the results of valuing Tuas Power. Such evaluation comprises objectively appraising the present situation and future development potentials of Tuas Power from various perspectives including the market, technological, financial and legal aspects. Key factors that have been considered include the growth of demand for power in Singapore, the market structure and the future competitive landscape of the power industry in Singapore, fuel supplies and costs, risk management capabilities, the technology and reliability of the existing generating units, repowering of the existing units, impact of unresolved legal issues, Tuas Power’s existing financial and operational conditions, structure and costs of the acquisition financing, and etc.. The evaluation of such factors was based on in-depth

- 7 -

and objective due diligence on Tuas Power conducted by various professional parties.

Finalisation of the purchase price for acquiring the 100% interests in Tuas Power was the result of a market-driven competitive bidding process. In the sale of the 100% interests in Tuas Power, Temesak followed the international common practice by adopting a two-stage auction process. The auction process was transparent, open and competitive and forms the basis of a fair price discovery mechanism. The final winning price was S$4.235 billion (approximately HK$24.238 billion), which reflected the value of Tuas Power as determined by the market. There has been no material change in the value of Tuas Power since it was acquired by Huaneng Group on 24 March 2008.

The total cost for Huaneng Group to acquire Tuas Power amounted to RMB21.92 billion (approximately HK$24.43 billion), comprising S$4.235 billion (approximately HK$24.238 billion) being the purchase price paid to Temesak, and RMB176 million (approximately HK$196 million), being the expenses (including interest of loan) directly incurred by Huaneng Group for purpose of acquiring Tuas Power. Huaneng Group´s sources of fund for paying such costs were as follows:

(1) an amount of US$985 million (approximately HK$7.674 billion) being capital injected by Huaneng Group into SinoSing Power, comprising (i) US$197 million (approximately HK$1.535 billion) from Huaneng Group´s internal sources; and (ii) US$788 million (approximately HK$6.139 billion) being a loan provided by The Export-Import Bank of China on normal commercial terms; and

(2) loans from various banks (upon completion of the Acquisition, repayment obligations of such loans are still with SinoSing Power) comprising (i) a loan of approximately US$600 million (approximately HK$4.675 billion) from The Bank of China; and (ii) a non-recourse project loan of S$2.25 billion (approximately HK$12.877 billion) from an overseas bank group.

Financial leverage is properly utilised in the above financing and debt structures. This combines with a competitive financing cost structure to ensure a reasonable level of investment returns.

The board of Directors believes that the price and the terms of the Acquisition are fair and reasonable to the Company and its Shareholders. In addition, the Acquisition is based on normal commercial terms. The board of Directors is therefore of the view that the Acquisition is in the interests of the Company and its Shareholders as a whole.

Tuas Power

Tuas Power is a power generating company incorporated in Singapore which is engaged in the business of generation, trading and retail of power. It has a generation capacity of 2,670 MW, representing over 25% of market share in Singapore. Tuas Power’s generation facilities consists of 2 x 600 MW oil-fired steam turbine units and 4 x 367.5 MW gas-fired combined cycle units. Its generating units are relatively new with records of steady operation and high reliability. The technical and economic parameters of Tuas Power’s units make Tuas Power one of the leaders in the industry.

Tuas Power sells its electric power output mainly through vesting contracts and direct sale into the power pool market. Vesting contract price is set by the Energy Market Authority (“EMA”) at the long run marginal cost and is adjusted by the EMA on a periodic basis for changes in the long run marginal cost and on a quarterly basis for inflation and changes in fuel prices. This helps protect margins of the generation business of the power companies in the Singapore market such as Tuas Power to a large degree. For the year ended 31 March 2007, vesting contracts contributed 64% of Tuas Power’s power generation sold. In addition, Tuas Power sells part of its generation output to the pool at the pool price. Pool participants bid into the competitive power pool market of Singapore every half an hour. Pool clearing price and the generation units dispatched are determined by matching the supply and demand curves. The gas-fired combined cycle units of Tuas Power enjoy advantages in the competitive biddings of the pool market given their relatively low cost and high efficiency. In addition to its power generation business, Tuas Power has a power retail business that offers a natural hedge to the price risk faced by its generation business as the retail price is linked to the prices at which the generation business sells its output.

For the financial year ended 31 March 2007, Tuas Power’s generation output and generation units sold were 10.27 billion kWh and 10.07 billion kWh, respectively.

Other information of Tuas Power is as follows:

THE EGM

The transaction as contemplated by the Transfer Agreement constitute a major and a connected transaction to the Company. As the transaction size of the Acquisition exceeds 2.5% of the applicable percentage ratios as calculated pursuant to Rule 14.07 of the Hong Kong Listing Rules, the Acquisition is a connected transaction of the Company, which shall be subject to Independent Shareholders’ approvals as required under Rule 14A.18 of the Hong Kong Listing Rules. The Company will convene an EGM in June 2008 to consider the approval of the Acquisition (including the Transfer Agreement). The voting at such meeting will be taken on a poll and the Company will make an announcement of the poll results. Huaneng Group, HIPDC and their respective Associates and shareholders who are involved in, or interested in the Acquisition (holding an aggregate of 6,121,786,667 shares in the Company, representing approximately 50.78% of the total issued shares of the Company as at the date hereof) will abstain from voting at the EGM in respect of the ordinary resolution to approve the Acquisition (including the Transfer Agreement). The Company expects that the notice of the EGM and the circular giving further information on the Acquisition and containing the advice of DBS, the independent financial adviser, to make recommendations to the Independent Directors Committee and the Independent Shareholders as to whether the terms of the Acquisition are fair and reasonable and whether the Acquisition is in the interests of the Company and the Shareholders as a whole and to advise the Independent Shareholders on how to vote, and the recommendations from the Independent Directors Committee will be despatched to shareholders within 21 days from the date of this announcement.

Upon completion of the Acquisition, Tuas Power and its subsidiaries will all become subsidiaries of the Company. According to chapter 14A of the Hong Kong Listing Rules, the substantial shareholders (and their associates) of Tuas Power’s subsidiaries, which are now independent and not connected with the Company and its connected persons will then become connected persons of the Company (“Tuas Power Connected Persons”) after closing. Certain existing transactions between Tuas Power (and its subsidiaries) and such Tuas Power Connected Persons will constitute continuing connected transactions of the Company after completion of the Acquisition accordingly. Such transactions are therefore subject to compliance with the disclosure and/or independent shareholders’ approval requirements under the Hong Kong Listing Rules by the Company. The Company shall make disclosure in this regard in due course.
