Start by turning off Caps Lock, and giving the forum more to go on. Consider: is it possible to obtain valuable and relevant answers to a question that uses only one sentence?

You could do as many do in developing countries and steal it. You hoard information, we hoard answers.

No I can't. You give no relevant information. Google: cheap power generation, and see what you get.

Does this help ? Personally, I wouldn't bet on it, but since you demand answers without even having the courtesy to let us know what you need , I guess it's as good as anything else you're likely to get . If not, then perhaps this will . For almost everyone else here, they'll know the answer as to whether those links are helpful or not , but as my former teacher Yoda mentioned to me before: "If in doubt you are, state clearly your problem you must, or helpful answer you may not receive ." Whatever my differences with him may be, I never doubted the wisdom of these words . And after this, perhaps you will too .

hey let me be straight! I am writing a feasibility studies on the production of detergent! the price of dis detergent is on the high side! Going back i saw tha if i can reduce to cost to power some of the plants used, the price will also reduce! This is why i ve decided to check out for cheaper means to generate power! I hope with this, You can help if u ve relevant solutions!

Here's a cheaper way to use power:

  • recycle all of the steam condensate from the plant
  • Make sure that insulation standards are high
  • Consider the water circuit - are there streams going to waste that could be re-used?
  • Consider the plant lighting. Is it all-incandescent, or are there more up-to-date lighting sources around?
  • Are timeswitches and occupancy detectors in use throughout?
  • Are recuperative flues in use on all combustion equipment?
  • Is tariff demand overdue for a revisit on the basis of peak power consumed and power factor presented to it?
  • Etc.

Thank you for your response! What i really need is an alternative to elctricity as the supply is not stable in my country. My plant has got to be powered by AGO (diesel) with the use of generators. What i need is an alternative. The cost is running my small company down.

Thank you once more!

How big is the plant load?

Well why didn't you say so before ? Now was that so difficult , letting us know what your problem is so that we can help you to come up with an answer ? Now do you see the wisdom of Yoda's words ?

Here's something to think about: many chemical processes use heat energy . Use some of your waste heat to preheat your raw ingredients. In this way, you can reduce your energy loading . Likewise, if you need to cool down your final product before packaging, then consider the possibility of using some of your raw material (e.g. incoming process water) as a coolant; or in short, try to recover as much wasted energy as possible . You'll be amazed how a little energy savings here and there can add up to a substantial savings at the end of the process . Also, what type of wastes will you produce? If they can be burnt to produce energy without violating your local environmental protection laws, then you may want to consider installing such a generator. Finally, if your plant is located next to a fast flowing river, you might want to consider installing a small hydroelectric turbine sufficient to power your plant.

So, have we learnt today's lesson yet, namely that if you're going to ask someone for help, then state your problem clearly so that they can advise you accordingly instead of expecting them to read your mind?

If your operation has relatively small motor loads and relatively high heat inputs, consider direct combustion for your heating requirements instead of electrical heaters.

If there is abundant wind energy in your area, a wind turbine might be worthwhile (initially expensive but cheap thereafter). Similarly, if there is hydropower potential, consider a turbine or Pelton wheel, depending on the water flow and elevation characteristics.

If you are located near any geysers or the like, how about geothermal? (This suggestion is probably whimsical, as nuclear generation would also be.)

Other than that, diesel-powered electrical generators are still often the most economical choice in remote locations. In that case, you may be stuck with what you already have.

Take advantage of as many insulation and heat recovery strategies as feasible; several good ones have already been mentioned.

Re: Cost-Effective Power Generation

In today's economy, I think that in the 100 kVA range, there is very little that can compete with diesel generation. Most "alternative" solutions require a pretty big investment in storage capacity, and batteries generally have shorter lives in reality than manufacturers would like us to believe. If you were looking at a smaller installation, or if you could adjust your working hours to coincide with energy availability, perhaps you could find a system that would meet your needs. Depending on location and logistics requirements, you may be able to replace the diesel with natural gas, but it is not clear to me that this is, as a general rule, a real cost saver. Your best bet is to look at ways to cut consumption- many suggestions have already been posted. You should do a realistic analysis of the power consumption- i.e., measure actual consumption of various systems, to determine where you could derive the most benefit.

upcoming engineer,

One choice is that you can try captive power generation- steam raising for power generation and after use of steam for heating uses.

Depending upon availability of the following you can try as fuels- Baccaas, rice husks, vegetable shells, saw dust etc should be workable. Check your regional availabilty and proceed.

This simple technology may help. One would need adjust the hot cold workings to size of turbine to obtain the required power output.
