With the Geysers project now in play, 30 MW under pipe (wells already drilled) this one should jump to the front of the line for development with HTM. This was a great move if they can sell the steam and make the same revenue as if building a new plant and selling electricity than that would be the move, otherwise with wells already drilled and ready Geysers still wins. Flash Steam plant would be relatively fast and would start additional revenue stream the quickest. Three fully active plants, three more in development, and more in the pipeline places HTM on solid footing for the long run, with such nice growth lined up I would expect the stock price to soon start elevating, and once started retracement would be doubtful as they now have a proven track record. The growth potential here is fantastic! Took a while to work out the efficiencies but with everything falling in place management is making smarter moves every quarter.
Disclosure: I am long HTM.
Additional disclosure: This is not a fast play rather a long churn, my rocking chair stock.
