An interview with Alison Thompson, Chair of the Canadian Geothermal Association

Originally Published in the ECOreport

British Columbia may have a “Trillion Dollar Opportunity,” and it is NOT LNG.*  There are more than 150 known hot springs in Western Canada. Look at the map below, most of the high generation temperature areas are in BC! According to Alison Thompson, Chair of the Canadian Geothermal Association, there is more than enough geothermal energy to power the province’s grid, yet none of these sites have been developed. Geothermal energy has never been invited to bid on calls for power. In fact, there isn’t a single developed geothermal site in all of Canada!

“Hot springs are great for the direct use of geothermal, but for power you’d have to drill,” Thompson explained. “Of course the hot springs are a surface manifestation that leads you to prospecting in that area.”

Borealis Geopower has two prospective sites for +/- 15 MWe power plants in BC. The Federal government and First Nations both support development of the Lakelse Lake site, but the province has yet to come to the table. The Canoe Reach Project is at the end of a transmission line and the nearby city of Valemount is experiencing routine brown-outs! They want to use the water left over from production for a community greenhouse and could also use it for public hot springs facilities.

There are many direct use applications, which do not need power. The heat from geothermal has been used for lumber drying, green housing, fish farming, milk pasteurization.

“On our mission down to Klammath Falls we visited a geothermal brewery that uses the heat from geothermal for the fermentation process,” Thompson said.

“If you look at what similarly geologic settings have, the sky’s the limit for BC,” she added. “We certainly have thousands and thousands of megawatts beneath our feet. We have so much of it that it truly could provide the province’s needs.”

Thompson added that it would be cheaper to develop geothermal than LNG and the jobs that came through it would be fairly evenly  distributed throughout communities and First Nations.

“Looking at a statistic from the US Department of Energy, the comparison between a natural gas plant and a geothermal plant,  geothermal is usually lower  for power price and we offer ten times the employment,” Thompson said.

Geothermal is also a good baseline power source, permitting the incorporation of more intermittent renewable energies into the grid.

“If someone was able to come online for a lower cost, you would just not use geothermal for those moments in time,” said Thompson. “Our ability to ramp up is as good, or better, than hydro. We really are a grid stabilizing feature and at a competitive cost, so perhaps you may want to turn off hydro and keep geothermal running.”

Looking south across the border, the US Energy Information Agency (EIA) says:

There are currently 64 operating conventional geothermal power plants in the United States, accounting for nearly 2,700 megawatts (MW) of total capacity at the end of 2013. Over three-fourths of U.S. geothermal power generation in 2013 was in California, largely because of favourable geothermal resources, policy, and market conditions in the state. The largest group of geothermal power plants in the world, a complex called the Geysers, located in Northern California, has more than 700 MW of capacity.

…. Geothermal plants are virtually emissions free, and unlike renewable sources such as wind and solar, they provide an available, dispatchable source of baseload power that is able to operate at a relatively high capacity factor….

There are 160 American projects in development that have a similar geology to BC.

EIA projects that America’s geothermal electricity generation could more than quadruple between 2012 and 2040, increasing to over 67,000 GWh.

Italy has been using geothermal energy for over a century. New Zealand, Iceland and California have utilized it for the past 50 years.

“This is just low cost base load energy that , for most people is comparable to hydro,” Thompson said.  “There are 25 countries using geothermal power and they, too, have hydro. It isn’t a competition, it is a complimentary thing to build for your system.”

B C knows Geothermal is a Clean, Low-Cost Option

BC Hydro has been aware of geothermal energy since since at least 1983. On page 229 of  the Joint Review Panel Report for the controversial site C dam it says, “BC Hydro, in its IRP, said that ‘geothermal appears to be a low-cost resource option,’ and ‘BC’s geothermal resource is estimated to total more than 700 MW of potentially cost-effective clean or renewable power.’

Given the opposition to site C in the Peace River Valley, and the fact thousands of acres of valuable farm land will be submerged if the project goes forward, it seems shocking to read BC Hydro said they were “not expected” to explore this option.

So why has British Columbia not developed ANY geothermal?

A spokesperson for BC’s Ministry of Energy and Mines said, “12 geothermal permits have been issued in recent years. Despite its relatively low cost, developers have not bid into the system primarily due to the high upfront costs and risks associated with exploring for and pinpointing geothermal resources.”

Thompson had a different explanation, “Of the 25 countries currently using geothermal power, BC is worst in class for its legislation. While there have been bright spots recently and there are two permitted projects CanGEA members are trying to further, it is not an easy sytem to navigate. There’s different ministries involved. With the last election now theres another ministry involved. There is the Natural Gas Ministry, the Energy Ministry and BC Hydro – a lot of bureaucracy and very little streamlining, and very little intent by the government to make geothermal a reality.

“We’d like to see them use their geothermal as a tool to stimulate industry, not as a barrier to keep industry at bay,” she added.

Most developers are going to less restrictive countries.

“At one point, before the financial market collapsed, there had been a billion dollars raised on the Toronto Stock Exchange and all but $25 million of that billion went to projects outside Canada,”  said Thompson.

    The US should declare Canada a US territory like we do Puertorico… we already provide for their security and send them jobs… this way we start getting something back… in the way of taxes and access to those lovely hot springs… this way everyone wins.. and anyone that doesn’t like this is a terrorist ;)

  • JamesWimberley

    Japan is another country that has failed to exploit good geothermal resources. There, many of the good sites are near spas in national parks that attract tourists. This can’t be a problem in BC. Indonesia also lags, though the geologically similar Philippines have many operating plants.

  • David in Bushwick

    Previous discussions here about geothermal potential being limited due to cost of initial investment makes no sense to me. A great number of people want to expand nuclear energy despite its eventual very high cost and years delayed construction that every power plant is guaranteed to have.
    Once a successful geothermal location is drilled, the costs thereafter are minimal compared with nuclear and it’s waste. And geothermal is on-demand power that is as base as you can get. Western politicians need to move geothermal to the front burner replacing very problematic nuclear.
    Drill baby, drill…

    • Larmion

      Part of the problem lies in failure rates. Almost half the cost of a geothermal stations comes from the drilling stage and over a quarter of all test wells fail to produce anything.

      If you get a nuclear plant financed, you know you’re going to get power. If you secure finance for geothermal, you still have a 25% chance of losing everything.

      For geothermal to succeed, a new system of subsidy is needed – one more akin to that used for nuclear than that for renewables. Let the government act as an insurer who shoulders part of the risk of well failures but give no or limited subsidy for the actual power produced. As with nuclear, the subsidies would be indirect in the form of loan guarantees and insurance rather than direct.

        Or when we drill a dry hole for geothermal we then convert that bore to enhanced geothermal. AltaRock recently demonstrated multi-level rock sheering in an abandoned geothermal bore.

        • Larmion

          Are you referring to the demonstration in a depleted borehole in the Gheysers? That project failed due to its inability to deal with thick serpentine layers – which is a bit of a problem for the company, since serpentinite minerals and their precursor peridotite tend to dominate the volcanic layers geothermal tries to exploit.

          Enhanced geothermal is a wonderful concept, but it needs more fundamental research first. Let’s try to fully exploit the conventional, easy sites first.

    • IdaRusskie

      I think you overstate the costs of nuclear power compared with the amount of power you can get out. These costs including the waste cost/decommissioning costs are amortized over the life of the plant which can be 80 years. while a geothermal plant will not last that long. Due to coosrtion you have to repalce the liner and pump is a short time frame.

      • Bob_Wallace

        No nuclear plant has yet operated 50 years. 80 years is a bridge too far.

        Some plants will be refurbished around their 40th birthday in order to extend them to 60 years. Other reactors have been and will be closed because the extra cost won’t make sense.

        Some new reactors may be designed to last 60 years. Of course engineering for those extra years increases costs.

        A recent analysis by Citigroup of the new Vogtle reactors found that the power from them will cost 11 cents per kWh. If there are no further budget/timeline overruns. And that it would not be reasonable to expect further reactors to be as cheap due to the very low interest rate Vogtle received.

        The EIA reports the LCOE of geothermal to run from 4 to 10 cents per kWh with a median price of 6 cents.
