Polaris Infrastructure: Deleveraged, Derisked
By Tom Konrad, Ph.D., CFA
Geothermal power is a type of renewable electricity that even the most conservative electric utilities find it easy to get behind. Like conventional coal and gas plants, it uses heat to drive a turbine which in turn creates electricity. The main difference is that the heat comes from natural geologic processes, rather than burning fossil fuels, making it renewable and free of greenhouse gas emissions, giving it considerable environmental appeal as well.
Where Geothermal Developers Stumble
The problem lies in the resource. The potential for producing power from solar, wind, and hydropower at any location can be...
Ten Alternative Energy Speculations for 2008: Geothermal, Wind and Wave, and Thin Film Hype
This article is a continuation of my Ten Alternative Energy Speculations for 2008, with picks #8, 9, and10 published last Thursday. If you haven't already, please read the introduction to that article before buying any of the stock picks that follow. These companies are likely to be highly volatile, and large positions are not appropriate for many investors. My least risky picks are part of that same article linked to above; the moderately risky picks are here. This article contains the most speculative three picks. #3 Nevada Geothermal Power (OTCBB:NGLPF or Toronto:NGP.V) US$1.29 or CAD$1.26 Geothermal first started catching...
Geothermal Power: Business in a Tough Neighborhood
Geothermal power producers use Earth’s internal heat to power electrical generators. It is the quintessential renewable energy source. Most geothermal plants are located adjacent to underground pockets of super hot water. Developers look for locations where these thermal reservoirs are near the earth’s surface, providing availability of the super hot water at a reasonable cost. Unfortunately, those locations are often in tough neighborhoods.
Ring of Fire
The overwhelming majority (85%) of current geothermal power installations in the world are located along the Ring of Fire that circumvents the Pacific Ocean. More a horseshoe than a circle, the Ring of Fire is a geographic anomaly that is...
Alterra Power: Deep Geothermal
by Debra Fiakas CFA Last week, one of the leaders in a development consortium, Iceland’s largest privately owned energy generator HS Orka hf, announced the completion of a project to prove the merits of deeper geothermal wells. The project in the Reykjanes Peninsula in southern Iceland reached 4,659 meters depth in January 2017, where temperatures measured 427 degrees Centigrade and fluid pressure was 340 bars. By all accounts the project was successful, suggesting that deep wells could a cost effective approach to geothermal energy. The drilling program was mentioned in early December 2015 a recent post “Hot...
What A Portfolio Approach To Climate Policy Means for Your Stock Portfolio
Portfolio theory can lend insights into which carbon abatement strategies policymakers should pursue. If policymakers listen, what will it mean for green investors? Tom Konrad, Ph.D., CFA Good Info, Not Enough Analysis I've now read most of my review copy of Investment Opportunities for a Low Carbon World. The quality of the information is generally excellent, as Charles has described in his reviews of the Wind and Solar and Efficiency and Geothermal chapters. As a resource on the state of Cleantech industries, it's generally excellent. As an investing resource, however, it leaves something to be desired. Each chapter is written...
Blindsided with Advance Warning
Holders of Ormat Technologies (ORA: NYSE) shares may feel somewhat blindsided by the cessation of operations at the Puna geothermal power plant on the Hawaii Island. Lava flowing from neighboring Kilauea volcano has overrun two of the geothermal wells as well as a warehouse and an electricity substation.
Shareholders cannot claim they were not forewarned. Ormat’s annual report for 2017 mentions the risk of volcanic eruptions seventeen times. However, since no geothermal power company has ever experienced an interruption in operations due to a volcanic eruption, investors most likely overlooked the real dangers of locating a business on top of geological ‘hot spot.’

How Geothermal Heat Pumps Can Soar Like Solar
Tom Konrad CFA Geothermal Heat Pumps (GHP) are a niche market. They shouldn’t be. Disclosure: Long WFIFF, short LXU puts (a net long position.) A Better Mousetrap? Ralph Waldo Emerson never said “Build a better mousetrap, and the world will beat a path to your door.” The mousetrap that likely inspired the misquote was invented seven years after his death. Unfortunately, many people take it literally. GHPs have all the hallmarks of a better mousetrap: They do the job of heating and cooling a building more efficiently than any other option. Despite...
Geothermal Tie-up
Ormat Technologies (ORA: NYSE) is buying U.S. Geothermal (HTM: NYSE) for $5.45 per share in cash. The offer represents a 29% premium to the HTM closing price the day prior to the announcement. The shares had been in a steady decline over the past several months, hitting a 52-week low of $3.11 earlier in January 2018. So while the offer price pales in comparison to the U.S. Geothermal’s all-time high stock price of $28.68 way back in October 2007, shareholders may be feeling a warm breeze coming off Ormat’s cash.
Should Ormat shareholders be as thrilled as the company ponies up $110 million...
US Geothermal Fizzles
by Debra Fiakas CFA Geothermal power generator US Geothermal (HTM: NYSE) came up short in reporting financial results for the first quarter ending 2017 - at least from the perspective of the four analysts with published sales and earnings expectations for the company. Operating revenue of $8.4 million slipped slightly from the same period a year ago, but produced slightly lower net income of $1.1 million. The company’s share was $260,000 or a penny per share. Not good enough say the analyst’s who were collectively looking for two pennies per share in earnings! Missing earnings expectations has...
Newsweek Special Report
"Experts generally agree that our current reliance on fossil fuels is unsustainable. Already oil is near $50 per barrel, and the great millions of Chinese and Indians destined to take to the road in the next decades have not yet gotten behind the wheel." This week Newsweek has written several special reports about alternative energy in all its forms. All of these reports can be found at the following link.
Ormat Steams On
Ormat Technologies, Inc. (ORA: NYSE) recently reported financial results for the three-month period ending September 2018 - the first full quarter without the revenue and earnings of the company’s Puna geothermal electricity generation project. In early May 2018, the Kilauea volcano erupted, giving the Hawaiian Islands a grand fire show. For Ormat and its neighbors near its Puna Geothermal Power Project the volcano was more nightmare than entertainment. Within a few days Ormat was forced to shut down the facility on Kilauea by removing surface equipment and plugging the geothermal well holes. Nonetheless, three well sites, the electric substation, an adjacent warehouse and drilling equipment were overtaken...
US Geothermal: Can A Reverse Split Heat Up This Stock?
by Debra Fiakas CFA
US Geothermal (HTM: NYSE) has been on our radar for some time. Despite considerable accomplishment in terms of building electricity output from a portfolio of geothermal power installations, investors seem reluctant to embrace the company and its stock. Earlier this week, US Geothermal management issued its usual quarterly update on its development work, this time detailing progress in expanding capacity and improving well performance on three of its geothermal installations. Altogether an incremental 90 megawatts are under development, which would triple the current power generation capacity of 45 megawatts. The company press release was met by...
Ormat Eyeing Storage M&A for Geothermal Projects
Jennifer Delony Reno, Nev.-based Ormat Technologies (ORA) is seeking mergers and acquisitions that will help the company enhance its geothermal projects with energy storage technologies, Ormat CEO Isaac Angel said on Nov. 4. “On the storage solutions side, we are progressing well,” Angle said during a 3Q15 earnings webcast. “I’m very optimistic that we will be able to add a lot of MW … and profitability to our existing power plants.” Angle said that he also is optimistic that the company will secure a deal soon that will initiate Ormat’s energy storage strategy. “We’re almost there,” he said....
Ormat: A Bargain Green Stock?
by Debra Fiakas CFA Everybody likes a bargain. Investors really like a good cheap buy. A review of our four alternative energy industries revealed several stocks trading below industry average multiples of forecasted earnings. Tracking the geothermal power generators has frequently taken us to the door of Ormat Technologies, Inc. (ORA: NYSE). Ormat has two revenue segments: power generation through geothermal generators and energy recovery and equipment sales to utility and industrial customers installing geothermal power plants. The company owns and operates plants with 626 megawatts generating power and has supplied equipment around the world for another...
Blue Mountain Disappoints; Nevada Geothermal Power Looks Like a Takeover Target
Tom Konrad CFA Which company might snatch battered Nevada Geothermal Power out of the scratch-and-dent bin for a song? When Raser Technologies (RZTIQ.OB) declared bankruptcy at the end of April, I shrugged it off. I saw the writing on the wall for Raser in September 2009, when they failed to get a DOE loan guarantee. But part of the letdown also had to do with resource risk: the company was producing consistently less power from their 10MW (rated) Thermo plant than expected. Early in 2011, Ram Power (RPG.TO, RAMPF.PK) stock was clobbered when they announced construction...
