Questions and Answers:
I suggest 16H35/40X4,it’s enough? the engine model that can used see following,
A. We are agree with 16H35/40GV-50 Hz x 4 �Please send me an offer for thoose .
You mean the exhaust steam from our gas generator? yes, we can offer turbine for you to improve the efficiency.
A. Exhaust gas from your gas generator. We suppose to produce low pressure steam (about 12 bar, 190 °C) from exhaust heat by using waste heat exchanger and use that steam for power generation by a LP steam turbine. Please send me an offer for a convenient turbine too.
1)Where will be the location of the plant and the project name?
A. City: East; 40.11 North ; Project name:
2)These power plant will supply power to steel or other metals melting, chemical industry or mains supply for city?
A. Will supply the national grid.
3)This power plant is going to tender from your client or already in your hands?
A. No tender! Already in our hands, but some competitors with prices about 500 $/kW.
4), Is there any other competitors with you? What do you need us to support you to get the order except technical?
A. Yes, Waertsilla, MWM are the main competitors. Not only the investment cost will be determinant, the operating cost is also very important. Please , let me know the data’s like, NG-consumption per kWh electricity and the total efficiency of the plant for offered gas generators.
Q：We suppose to produce low pressure steam (about 12 bar, 190 °C) from exhaust heat by using waste heat exchanger and use that steam for power generation by a LP steam turbine. Please send me an offer for a convenient turbine too.
A.The steam from exhaust heat by using waste heat exchanger is not enough to drive turbine for power generation, just can be used for heating the mineral oil you have said before.
Q：let me know the data’s like, NG-consumption per kWh electricity and the total efficiency of the plant for offered gas generators.
A.NG-consumption per kWh electricity is 162g and the Brake Thermal efficiency of the engine is 44.6%
2MW gas engine generator with cogenerating system
1- what is the efficiency of gas turbine when we use natural gas,
A. The total efficiency of the plant is 49.5%
2- what is the efficiency of gas turbine and cogenerating
A. The steam from exhaust heat by using waste heat exchanger is not enough to drive turbine for power generation
3- please inform me the total natural gas consumption per hour .
A. NG-consumption per kWh electricity is 157g ,so the Total natural gas consumption for 2MW is about 314000g per hour.
4- how many hours you will guarantee it
A. One year after delivery.
5. they are willing to pay 20% of total amount to bank to get loan but it take some time. so if you provide the loan from chinese bank they can visit you and close the deal immediately
A: we need at least 30% of the employer's own financing or equity, among which we can offer 5-10%, you if your employer has 20% of the equity, and then he can let his bank or bank syndicate issue our bank financing guarantee, and buy our Sinosure insurance company premium, it is possible that our bank will offer financing of 70% of the EPC price.

0n 25mw Hyundai gas engine generator power plant 50% investment from our side:
Yesterday (October 18th, 2011) we signed a MOU for 50%:50% investment for a 25mw gas engine generator plant by using our Hyundai 18H35/40GV, and the EPC price is about 25.2 million USD for 3 unit 18H35/40GV of the Hyundai gas engine sets, efficiency of the plant is about 42%. The 18H35/40GV and 16H35/40GV have been listed as approved engines in your MoP in Iran.
So please locate the employers who already got PPA with your government.
Yes, the plant can be installed with CHP to increase efficiency too.
So now you have MOU and you can introduce them for our reference but
limit for efficiency is 45% without CHP, could you confirm?
A: As I have informed you in last mail that our system efficiency is more than 44%.
Why this finance is 50%:50%? Is it means you can not finance up to 85%?
A: yes, we can provide financing up to 85%, against bank guarantee, but to our experience, it is very difficult for financing to private project in Iran due to that they can not provide acceptable bank guarantee.
But if your projects or projects package value is over 100 million USD, and you can provide bank guarantee, then we can talk on EPC and financing through biggest EPC contractor.
Could you say to us step by step what we have to do for financing 25MW gas engine power plant?
A: I mean for 50%:50% investment is that we can invest 50% of the project by supply EPC content to your project, your side provide 50% of the project, so it is investment not financing. we have signed MOU for two projects in such manner, each is 25mw gas engine generator projects. now you first provide PPA copies and also technical documents to us and fill in the attached questionnaire so that we can design and then you are invite to come to Beijing to hold face to face negotiation.
