Approximate Economics of Electrical Power Generation by Natural Gas

This was economic before the big hike in gas prices. Not sure now.

I am interested in the possibilities of using gas generation of electricity for my cryptocurrency mining.  This page covers the fuel consumption of that approach.  The following chart approximates the fuel consumption of a generic gas generator based on the size of the generator and the load at which the generator is operating at.  Please note that this table is intended to be used as an estimate of how much fuel a generator uses during operation and is not an exact representation due to various factors that can increase or decrease the amount of fuel consumed.

You can see in the chart that there is a most efficient usage point on all these graphs.  I will chart this with excell later should I need to.

Is Net-metering available where I live?

Net-metering is available to customers installing eligible energy production facilities throughout the FirstEnergy service territories. Each kWh of energy received from the customer offsets the energy delivered to the customer on a one for one basis, up to the amount of energy delivered to the customer during a billing period. Excess energy received from the customer is credited to the customer's account at the applicable generation component of the customer's rate schedule. See: http://www.puco.ohio.gov/PUCO/Consumer/Information.cfm?id=8510

  • Guess: This phrase above means you get compensated for the kWh charge but not the network distribution charge. – need to confirm / deny with Roger's friend or FirstEnergy
