Off-grid power in Rajasthan, India

I recently returned from a trip to Rajasthan, India.  While there, I came across an off-grid power opportunity at the Amber Fort near Jaipur.  The fort has a restaurant and gift shop facilities (with a stereo and satellite TV – see the video I took).  The facility is powered by a Cummins diesel genset.

When I saw diesel genset, I became curious about the levelized cost of energy (LCOE) for this off-the-grid system.  Here is a spreadsheet where I made some guesses about the system cost.  I came up with a resulting LCOE of $0.3144/kWh for the power from the diesel genset.  I tried to make assumptions that if anything would bias to cost to be lower than what it actually is.  $0.31/kWh is a high price for electricity and provides an attractive opportunity for distributed solar and wind power.  While travelling through India I saw a number of off-grid communities, so I expect India to be a large market for distributed clean power.
