Economics of Gas turbine Vs Diesel Engine for Power Generation

Since your location is in Saudi Arabia you can inquire from Olayan Group power generation. One Power Plant in Riyadh (PP-9) more than 3000MW natural gas power plant located in Dammam hi-way and yet expanding more units, interconnected to entire Riyadh-Kharj HT transmission grid. KSA is oil producing country but SCECO prefered nat. gas PP instead of diesel PP because of less operating and maintenance cost. Diesel fuel cost 21 halalah at nat gas about 18 halala, gasoline 91% is 45 halalah and 95% is 60 halalah.

You need to consider if you have a use for the exhaust heat. There are thermo-electric generators that can convert heat delta T to electricity or heat exchangers to make steam. Thus increasing the cycle efficiency. Don't forget to take into account your in-house power needs if a system gets complex, thermal plants can use 7% to 10% of there generation for in-house loads.

There is also the possibility of a steam, hot water or chilled water customer that the exhaust from either diesel or GT can be routed thru a chiller or boiler, 4-8MW GT can drive a 500kW+ back-pressure ST producing 10,000lbs/hr 50psig steam or more.

Staffing is dependent upon the system and it's location, safe control systems can usually summon an operator and if necessary shut a unit down without operator intervention. We did this with a 4.5 MW GT, 600psig waste-heat boiler and 500psig back-pressure ST, which if it shutdown a back-up boiler in hot standby picked up the load.

i am interested in DG heat recovery CoronaCameraman.

I know that cummins and Caterpillar have DG that one can recycle heat from. Can you give me information on any DG with integrated heat recovery?

Thanks

There are only three options you can choose in Saudi Arabia. Since my job location in Gulf Regions including Saudi Arabia. In Saudi Arabia kingdom wide military projects(Saudi Arabia National Guard or SANG). Some military sites or Firing Range Complexes are few kilometers from SCECO LV/MV substation wherein it is difficult to run commercial power if the LOAD connected in that particular areas will not be within the bracket of SCECO minimum power requirement policy..(meaning it is small load) to justify SCECO to give you the commercial power. So the option is to contruct your own independent power plant. Here is Saudi Arabia it is like a fairy Tales if you are thinking to construct the thermal/geothermal/hydro-plant here. The possible options here are;

1. Diesel Fired Power Plant

2. Natural Gas Fired Power Plant

3. Nuclear Power Plant

But no. 1 is most prefered because of cheap diesel in Saudi Arabia. Just like you buy brand you car today and throw it in junk shop the next day and buy another one brand new.

So you said your work location is in Saudi Arabia either you decide to have a DG and NG power generating plant is not the big deal here. Since we already had constructed plenty of generating plants kingdom wide such as Caterpillar gensets from Zahid Tractor; Cummin gensets from Olayan Group and you can let them configure to fit your needs and demands....then it will end up no headache for you.
