John McIlveen, a veteran securities analyst specializing in renewable power, turns The Energy Report on to a hot but hardly new source of energy in this exclusive interview. Geothermal power runs 24/7, is clean, cost-competitive and ready now. McIlveen, who recently joined Jacob & Company, an independent investment bank providing financial services to the renewable power sector, shares the names of some small geothermal companies with big multiples in their future.

The Energy Report: Let’s start with your outlook for geothermal. Where is it going?

John McIlveen: For starters, geothermal is the only renewable power that is base load, so it can run 24/7. Wind is only available 30% of the time and solar, 12%. Geothermal is 98% available. If you’re trying to retire coal, gas and nuclear plants, you’d have to triple, quadruple build to replace them with wind. You’d probably need a gas backup in case the wind’s not blowing. Geothermal is actually more available than coal and gas, which are typically around 80%. So that’s the first point.

Second, like any renewable, geothermal doesn’t have a fuel cost. So if you manage the amount of flow you take from the earth with the amount you pump back into the earth, you can essentially create a closed loop sustainable resource. The fact that it requires no fuel means there’s no risk exposure to the price of oil, the price of gas, etc. And, it’s ready now.

TER: The higher the price of oil, the more attractive the alternatives become. But you’re saying that’s not the case here.

JM: Utilities treat the price of power as a “levelized” cosJohn McIlveen, a veteran securities analyst specializing in renewable power, says geothermal power runs 24/7, is clean, cost-competitive and ready now.t. This compares all costs—capital and operating—divided by the number of megawatt hours generated over the life of the plant. For example, they’d use 30 years for geothermal; 25 years for a coal plant, and compare costs on that basis. Geothermal is as competitive as coal; it’s clean and available 24/7.

TER: It’s cost competitive so it doesn’t matter what the price of oil is.

JM: That’s right. It obviously doesn’t move with oil, but when oil is up at these levels and higher, then it sure looks good. However, it’s cost competitive with coal now.

TER: Because coal is the cheapest source compared to oil or natural gas?

JM: Absolutely.

TER: It just has that nasty environmental problem.

JM: Geothermal has a much smaller footprint than other alternative energies. Because geothermal sites are often remote, NIMBY is not an issue. Geothermal exists where tectonic plates intersect in zones of high seismic activity.

TER: So typically you don’t get the NGOs protesting?

JM: You can usually tuck geothermal sites behind a mountain. Last week I toured Nevada and we drove for four hours down a dirt road. We never saw a single car during the entire trip and only two ranch houses but there were three geothermal plants.

TER: Describe the typical geothermal plant.

JM: It’s closer to the ground than a gas or a nuclear facility. Anything that’s burning something—gas, coal, and nuclear all boil water—requires a large boiler and a tall smoke stack. Geothermal doesn’t burn anything. The plants are only about three-stories high, so they’re unobtrusive. Their gathering systems—the pipes that connect the main plant to the different wells—are generally located about half a kilometer apart, so they don’t limit the use of the land. You could still farm it, feed cattle on it or even build solar power plants on it.

TER: I live near the geysers in California. There is concern that pumping water from those areas could cause earthquakes. Are earthquakes more likely in a geothermal area?

JM: By definition, you find geothermal activity in earthquake prone areas.

TER: I see.

JM: They’ve been trucking in treated wastewater to replenish the reservoirs in California’s geyser zones, which they hadn’t done for years. All of the geothermal plants operating throughout Nevada and Utah re-inject water. There’s 9,000 megawatts worldwide of this, but I haven’t heard that this is a problem. But geothermal plants are located in earthquake-prone areas. There was a situation in Switzerland where they were experimenting with one of these Enhanced Geothermal Systems (EGS). What that means is, although there’s lots of hot rock down a couple of kilometers, there’s no natural water reservoir.

So, in order to create electricity, you’re going to have to bring in water from an outside source, put it down the well, let it heat, and then bring it back up. That process triggered a series of small tremors strong enough to break a few windows. In this instance, they added water where there wasn’t any in the first place. Australia is at the forefront of the geothermal arena. They’re doing some pretty large-scale pilot projects there and I haven’t heard of this being a problem.

TER: Are costs still coming down?

JM: Geothermal has been around for 100 years but new developments continue to make it more efficient and bring costs down. For example, advances in oil and gas drilling techniques are fully transferable to geothermal. There are a number of new technologies being tested that operate at much lower temperatures. That means shallower wells could be drilled maybe a half a kilometer instead of three kilometers. There is also the possibility of tapping areas that lack the hot temperatures you really need, but are still warm enough to generate power.

TER: Obviously there’s a renewed interest in geothermal. I’ve got the book: The Geysers Album: Five Eras of Geothermal History. This shows geothermal being used in California as far back as the 1870s. It’s been around a long time. What’s prompting this renaissance?

JM: In order for any product to have that hockey stick curve to it, it’s got to be better and cheaper. It’s clearly better if it has zero fuel costs, no commodity risk, and is a closed loop, non-depleting resource. But now it’s also cheaper and cost competitive with coal. With all of those advantages, the product’s got to take off.

TER: What about some companies that you’re currently recommending or looking at in that space?

JM: We’ve got five junior geothermals on the Toronto or the Toronto Venture Exchange. Then there are two on the NYSE—Ormat Technologies Inc. and Raser Technologies, Inc. Raser has an electric motor business as well.

TER: So it’s not a pure play.

JM: That’s right. Since Ormat is the granddaddy, let’s look at that first. Obviously, it’s been cut way down and is 50% off its annual high. The junior geos are all about 20% to 35% of their annual highs. They fell to a quarter and the big daddy fell by a half. In a normal market, Ormat was trading roughly 20 to 25 times trailing enterprise value to EBITDA.

To put that into perspective, the big $20 billion utilities usually trade around 9 times enterprise value to EBIDA. This is because the big utilities have a 1% growth rate and they pay a 4% dividend. On the other hand, Ormat is going to double its megawatts over the next, say, three years of construction, so the difference is really high growth vs. no-growth. That’s why you get the nice big multiple and that’s where all of these little geos are going because every one of them has a pipeline full of projects.

For example, Ormat is generating on 400 megawatts right now. Only two of these are generating, Polaris Geothermal and U.S. Geothermal, at 10 and 17 megawatts, respectively. However, they have the capacity for 500 megawatts and 250 megawatts. The others have pipelines ranging from 200 to 400 megawatts. This gives them a locked-in growth profile for a good ten years after they get going. So this bad market has not hurt the fundamentals.

What’s attractive about these geothermals is their 20-year Power Purchase Agreements (PPA). This is an agreement with the local utility or the grid operator so you know your price and quantity, and you keep it for 20 years. There are no surprises. That means you have a predictable cash flow for 20 years at IRRs in the mid teens if you’re not counting any subsidies or incentives such as the PTCs. The long-term average of the market is in the 10 to 12% range. So, if you pick the right project, it could be a perfect hedge with a superior return and none of the volatility.

TER: Are Polaris and Geothermal are actually in the business of producing electricity right now?

JM: Yes. Polaris generates 10 megawatts. U.S. Geothermal has about 17 megawatts.

TER: But they are expanding that.

JM: Oh, yes.  Continued...
