Best Plan for 100MW Gas Turbine Power Plant
Best Plan for 100MW Gas Turbine Power Plant
(OP)
Please my organisation is intending to build an industrial park, that will consist of fertiliser, methanol and ethanol plants, with a combined power requirement of 100MW [redundancy included].
We are looking at gas power turbines as a power source. Currently, we need a 'best' plan for this. Should we go for several turbines [e.g. 25 MW X 4] or just [50MW X 2] or even just a turbine of 100MW. Advise.

Your employer should really consider getting some expert help with this. There are plenty consulting engineers such as Parsons Brinkerhoff and Sinclair-Knight-Merz to name a couple who specialise in providing this service. A 100MW generating station is a pretty expensive proposition - get some proper help.

There are a lot of options and possibilities: you could run the gas turbines open cycle if the ST is unavailable for example, which would result in an awful efficiency and heat rate but would save the cost of a second steam turbine. Software like GT-Pro allows modelling of the different plant configurations to determine the optimum for your application, but it is specialised and very expensive. That's one of the reasons why I suggested getting help from people who do this type of work all day, every day.

I second the idea of a good A/E, just get one that has done this type of work before, preferably with the exact processes you are dealing with.

RE: Best Plan for 100MW Gas Turbine Power Plant
thats an option my employers are willing to look at in the future. But now we are dealing with captive power generation.
We are currently in talks with a gas engine vendor on the possibility of using gas engines to generate 100MW. I have reservations on this though. Looking at initial cost , perfomance,load following xtic, e.t.c, I am trying to make a justification for gas turbines.
Any ideas from anyone?

Power requirements are 24/7 for the plants, at least for baseload operation.
RE: Best Plan for 100MW Gas Turbine Power Plant
The available ratings of equipment from different manufacturers to give the best split
Remote location where parts and services are difficult to come by
vs.
A location near industrial compounds and cities
Capital expenditure vs [operational cost + flexibility]: more units give better flexibility but higher operational costs (personnel, spares)
100MW in today's state of the art is a "modest" output requirement, easily achievable with just one unit (e.g. a Frame 9E - for a 50Hz location - or similar type of unit)
Also to consider are the environmental requirements (NOx, CO2) and other local regulations. Do you require Dry NOx control? Is steam or demin water available for NOx abatement?
Another option would be 3x40MW units (Frame 6B or similar type of unit)

Likewise you should consider operating hours/cycles. are you going to be cycling hence requiring more maintenance or on a 24/7 run?
The other thing to think about is with just 1 GT your stuffed if it fails. but with more than 1 you can still provide partial load when one fails.
My other question, isnt there any Power Station already around your area that you can set up a contract with? hence removing the risks totally from your end. Because you have to think going forward
. you'd need more employees to cover the GT,
. need contracts with maintenance parties who are experts on different GTs, trust me these guys can stiff you up easily too so be careful with OEMs!!!
. won't setting up a contract with the closest PS to supply this power sort out the issue? but as one of the guys said if you dont have a PS close by that's tough!
Im obviously not an expert like some of these guys here but thought i'd just drop my opinion on this topic
Please do drop more information or knowledge you have on this subject they will all be taken in and appreciated.

Are you looking at some sort of cogen options too? Because you may have a good opportunity to develop something quite efficient.
