In discussions with Serra Geothermal Power's Patrick Moodie (IR)....the easist coorelation is for each 20MW well produced it should increase $1.22. This naturally fits their model, other companies with more/less shares would be impacted differently.
The industry needs to establish some guideline for investors!
He indicated the fee paid by utilities for their power is in the range of $95/MW....then it is discounted for a net present value on their books.
