PGV aims to return to full power generation by end of year

OrmatThe Puna Geothermal Venture power plant restarted in early November — more than two years after the 2018 eruption of Kilauea volcano forced it to stop producing electricity — and is ramping up to full production capacity.

Hawaii’s only geothermal power plant was isolated by lava during the eruption. Lava also destroyed a substation and covered a few geothermal wells, as well as cut off road access to the facility.

Mike Kaleikini, PGV’s senior director, Hawaii affairs, said Friday the plant now is generating approximately 20 megawatts of power and is targeting a return to full capacity — 38 megawatts — later this year.

“We’re pleased (with) where we’re at, but we want to get back to full capacity,” he said. “Our target is to get back to full capacity.”

In January, only one production well and two injection wells were operating.

As of Friday, however, Kaleikini said PGV has three production wells and three geothermal reinjection wells in service.

Two more reinjection wells — one new and one restored after being covered in lava during the eruption — are expected to be operational later this month, he said.

“We’ll see how these how these two additional wells contribute, then based on that, we’ll decide what the next steps will be in regards to drilling (additional wells),” Kaleikini said.

PGV production at nearly 30% capacity

OrmatPuna Geothermal Venture is now producing 11.5 megawatts of power, plant leaders said during a community meeting Wednesday.

The power plant restarted in early November, more than two years after the 2018 eruption of Kilauea volcano forced it to stop producing electricity.

Hawaii’s only geothermal power plant was isolated by lava during the eruption. Lava also destroyed a substation and covered a few geothermal wells, as well as cut off road access to the facility.

During the virtual community meeting, plant manager Jordan Hara said PGV is producing about 30% of its capacity.

The company said late last year that production was expected to ramp up to approximately 15 megawatts by the end of the year, should an additional production well be successfully connected to the power plant.

Puna Geothermal Venture Video Conference Mike Michael Kaleikini Jordan HaraOne production well and two injection wells are currently in operation, according to Mike Kaleikini, PGV’s senior director, Hawaii affairs. Kaleikini said that full production capacity is 38 megawatts.

“Our plan is to continue working until we’re at full operations, and we’re targeting the middle of 2021,” he said.

According to Hara, a new well is expected to be completed in March or April.

An application for an amended power purchase agreement between the power plant and Hawaiian Electric — which includes a proposal to modify plant equipment — is still under consideration by the state Public Utilities Commission.

Under the new agreement, the rate paid by the utility to PGV will be fixed and no longer linked to the price of oil.

By eliminating the volatility of oil prices from the rate paid to PGV, the new fixed-price contract will ensure that bills are more stable, Hawaiian Electric said previously. This new pricing arrangement follows guidance provided by the PUC.

As part of the amended agreement, PGV agreed to modify its current facility to provide an additional 8 megawatts of energy and firm capacity, which will further reduce electric bills and the use of fossil fuels to generate electricity.

Ormat Resumes Operation of Puna Power Plant

OrmatCompany Release – 11/12/2020
Puna Supplies Electricity to Hawaii Island Grid After Two and a Half Years of Repairs Following Volcanic Eruption

Expected to Ramp Production to 15 MW by Year-End 2020

RENO, Nev., Nov. 12, 2020 (GLOBE NEWSWIRE) — Ormat Technologies, Inc. (NYSE: ORA) today announced that it has resumed operation of the Puna Geothermal Power Plant, which supplies electricity to the Hawaii Island grid, two and a half years after the eruption of the Kilauea Volcano disrupted operations.

Electricity production at Puna resumed on November 5th, 2020, and the plant is currently delivering between 1 to 2 MW of energy to the utility grid. Ormat expects to gradually ramp up production to approximately 15 MW by year end 2020, subject to the successful connection of an additional production well to the power plant.

Ormat’s recovery plan included building a new electricity substation and adding new geothermal wells. The company currently expects that completion of additional well field work, planned to occur over the next 6 months, will enable the power plant to further ramp up production, with the goal of resuming full operations by the middle of 2021.

“I truly appreciate the dedication and hard work of the Ormat team over the last two and a half years,” said Doron Blachar, Chief Executive Officer of Ormat Technologies. “The Puna Power Plant provides clean, renewable base-load energy for Hawaii, supporting the state’s standing as a recognized leader in green power, increasing Hawaiian Electric’s generation reserve margins and reducing the need of fossil fuels to generate electricity for the Island. Ormat and Hawaiian Electric have worked closely together, and strived thorough challenges imposed by the COVID-19 pandemic in order to bring the Puna Power Plant back online for the residents of Hawaii. While the ramp to full capacity is taking slightly longer than we recently anticipated, I believe that we will be able to bring Puna back to normal operation during 2021.”

Nicole Lautze: Candidate for Geothermal Rising Board of Directors

Nicole Lautze Geothermal Rising Geothermal Resource CouncilOur Director Nicole Lautze is a candidate for the Geothermal Rising (formerly Geothermal Resource Council) Board of Directors. Her plans as a board member and biography:

Plans: “As a board member, I will ensure that GRC is meeting the needs of its members, will promote outreach that emphasizes the unique benefits of geothermal to governmental agencies and communities, and will encourage environmental stewardship, public acceptance, and developing the next generation of geothermal leaders. Further, I will contribute my scientific expertise, knowledge of geothermal exploration in the Pacific Rim, and experience working with multiple governmental agencies, private organizations, and the communities.”

Biography: “My passion for geothermal is based on my fundamental concern for the planet. I am a tenured faculty researcher at the University of Hawaii at Manoa where I founded and direct the Hawaii Groundwater and Geothermal Resources Center (HGGRC). During my eight years as faculty, I have secured grants/donations worth over ~$24.5 million as Principal Investigator and co-Investigator, and funded the employment of over 50 postdocs, staff members, and students. As a testament to my accomplishments, I received the Clean Energy Education & Empowerment (C3E) Education Award from the MIT Energy Initiative and the Stanford Precourt Institute for Energy in 2017. While my geothermal research has been primarily focused in Hawaii thanks to the DOE-funded National Geothermal Data System and Hawaii Play Fairway projects, I am excited to be now expanding to U.S. territories and other countries.

“While leading the five-year-long Hawaii Play Fairway project it was an honor to work amongst bright and excited colleagues at all levels. Our drilling project on Lanai resulted in not only data that confirmed a potential geothermal source, but also hydrological findings that will inform groundwater management across the state. Outreach is key too. In 2015 I launched the HGGRC website (www.higp.hawaii.edu/hggrc), which has generated hundreds of thousands of hits and reinvigorated some datasets that would otherwise have been lost (including drill core photos).

“I earned a Bachelor of Science in Geology from UCLA (among the top 50 graduating seniors), and a PhD in Geology and Geophysics from University of Hawaii at Manoa. I received two Fulbright fellowships (to Italy and Peru), a National Science Foundation International Postdoctoral Research Fellowship (to Italy), and a U.S. Geological Survey Mendenhall Postdoctoral Fellowship.”

Hurricanes, heavy rain critical for Oʻahu’s groundwater supply

Daniel Dores collecting data out in the fieldLocated within the most isolated archipelago in the world, Hawaiʻi is critically dependent on a clean, ample supply of fresh water. New research led by University of Hawaiʻi at Mānoa scientists indicates that rain brought to the islands by hurricanes and Kona storms can often be the most important precipitation for re-supplying groundwater in many regions of Oʻahu.

“The majority of Hawaiʻi’s freshwater comes from groundwater,” said Daniel Dores, lead author and groundwater and geothermal researcher in the UH Mānoa School of Ocean and Earth Science and Technology (SOEST). “In this study, we investigated the relationship between trade wind showers, major rainfall events like Kona storms, and groundwater.”

Dores and a team of scientists from SOEST and the Hawaiʻi Department of Health collected rainfall around Oʻahu and analyzed the stable isotopes of rainwater, chemical signatures in the water molecules. They compared the chemical signatures in rainwater to those of groundwater to determine the source of water in the aquifers—event-based rainfall or trade wind-related rain.

rain chart groundwater recharge“Because windward and mauka showers are so common, it is easy to assume that is the main source of our drinking water,” said Dores. “Also, large rainfall events such as Kona storms result in significant runoff into the oceans. However, our research found that a lot of the rain from Kona storms makes it into our groundwater aquifers and is an important source of our drinking water.”

Hawaiʻi is experiencing substantial changes in trade wind weather patterns, and precipitation events could become more extreme. Co-authors will continue researching to understand more about local and regional groundwater recharge and water quality.

“By better understanding how our groundwater is impacted by these extreme precipitation events, we can better protect the resource itself,” said Dores.

Henk Rogers and the blueprint for a 100% renewable Hawaii

Does wind power have a future in Hawaii, or do you think we should go mostly solar, because of reduced opposition to low-profile solar projects?

Wind power does have a future in Hawaii, especially on the Big Island, but you leave out the biggest potential energy source in the state: geothermal. There is more than enough energy under the Big Island to power the entire state for the rest of time. I’ve been to Iceland and I’ve seen how it transformed their economy without any detrimental environmental or cultural damage. Quite the opposite, geothermal put Iceland on the world map. They went from being a distant fishing community using coal for heat and energy to being 100% renewable and becoming the biggest producer of aluminum in Europe.

Geothermal is more complicated in Hawaii because of our active volcanoes. Do you support an expansion of our geothermal energy supply even with active volcanoes Kilauea, Mauna Loa and Hualalai, all areas that would be, by necessity, the potential locations for additional geothermal facilities? Our one existing plant, Puna Geothermal Ventures, was quite lucky to escape complete destruction in the 2018 Kilauea eruption, but it has yet to come back online.

Geothermal may be more complicated, but not as complicated as not doing it. As long as we don’t put all our eggs in one basket by building one massive plant, we should be fine. Geothermal means volcanic activity no matter where you go. Puna Geothermal was indeed spared. I believe the reason that it’s not yet on-line is transmission lines are still down. Any source of power that includes transmission lines is equally vulnerable.

Given the difficulties with geothermal and biomass, do you see the Big Island’s energy future consisting of a large majority of solar, wind and battery storage, with perhaps some hydrogen production and storage for long-term storage if that’s required (a recent Wartsila study didn’t find any hydrogen storage required for Hawaii due to our climate)?

If we’re smart, geothermal will become the biggest source of renewable energy on the Big Island. If we’re really smart, geothermal will produce serious amounts of hydrogen, enough to export to other Hawaiian islands as a back-up fuel for the intermittent energy sources, wind and solar. If we’re geniuses, we will set up a massive hydrogen export business and sell hydrogen to Japan. We could be the Saudi Arabia of hydrogen.

Fervo Energy Aims to Increase Geothermal Well Productivity

Fervo Energy Elemental Excelerator Tim Latimer

We are pleased to welcome a new crew of ground-breakers and market-makers from the 19 companies in Elemental’s Cohort 9.

It seems fitting that we cross the 100-company threshold for our portfolio here at the outset of what must be a decade of climate action. Because the price of keeping the status quo grows steeper every year, from the human and economic toll of climate-related disasters, fires, heatwaves, and other environmental stresses to the jobs left on the table by not accelerating towards a carbon-free, regenerative economy.

We’re grateful to partner with this latest group of innovators and, with a portfolio that’s now 117 companies strong, work together to commercialize an abundance of solutions to reverse climate change — starting today. In total, we’re funding Cohort 9 with over $7M to anchor $15M of projects, which are designed to scale 10x within two years.

ENERGY
“While we are witnessing the devastation that climate change is already laying on our most vulnerable communities, there are plenty of reasons to remain optimistic. The energy companies in our latest cohort have developed innovative approaches to sustainable urban development, maximizing renewable power generation, and aiding in a just transition to a clean-energy workforce. We are excited to partner with these companies actively scaling up technologies that can transform our communities by offering access to clean, resilient, and affordable power for all.” — Nneka Uzoh, Director of Energy Innovation

Fervo Energy | EQUITY & ACCESS
Scalable and affordable geothermal power for 100% clean energy

Why do we love them?
Geothermal power, which currently accounts for less than 1% of utility-scale electricity generation in the U.S., is poised for a breakthrough. Sourced from heat generated by the Earth’s core, geothermal energy clean, available 24-7, entirely homegrown, and virtually unlimited. But that’s just one piece of why we’re so excited by Fervo’s approach to rapidly scaling and increasing the productivity of geothermal wells. As demand drops out and the economics stop adding up for the fossil fuel industry, geothermal presents an opportunity to immediately transition the tens of thousands of Americans employed by oil and gas companies into a clean-energy workforce. Fervo Energy’s CEO Tim Latimer, who was formerly a shale gas drilling engineer, understands that many of the same skills and even equipment used in oil-field drilling can, instead of producing hydrocarbons, be repurposed overnight to tap into geothermal wells and produce abundant, carbon-free electricity.

Puna geothermal plant can restart without further review

An aerial view of the Puna Geothermal Venture plant.

The Hawaii Department of Health determined the state’s only geothermal power plant does not need an additional environmental review in its ongoing effort to restart after the facility was shut down by a volcanic eruption.

Puna Geothermal Venture is in the review process for a noncovered source permit, which is effective for five years, The Hawaii Tribune-Herald reported Thursday.

Puna Geothermal Venture and Nevada-based parent company Ormat Technologies Inc. hope to produce electricity again by the end of September following technical delays in rebuilding the Big Island facility.

The 38-megawatt power plant’s geothermal wells were isolated or covered by lava in the Kilauea volcano eruption that began in May 2018. Puna Geothermal supplied 31% of Hawaii island’s electricity before the shutdown.

State Health Director Bruce Anderson said in a Sept. 4 letter that the health department had “taken a hard look at all the environmental factors” and determined a new or supplemental review was not needed for the plant’s reopening.

Opponents of the plant include sustainable energy and environmental advocacy groups Puna Pono Alliance and Malama O Puna.

The state Department of Land and Natural Resources earlier this month denied an environmental review request by Pele Defense Fund, an advocacy group for traditional Hawaiian practices.

Puna Geothermal Senior Director Mike Kaleikini said Wednesday that the company continues to make preparations for the plant’s restart.

“We wanted to come online earlier. But the closer we got to the time, there was more work that needed to be done,” Kaleikini said. “Our target is still the end of the month, until such time something else might pop up or whatever.”

The company plans to initially bring online its smallest unit, which produces 3 MW of power. Work will then continue to restore capacity to 38 MW, Kaleikini said.

There is an amended power purchase agreement with Hawaiian Electric Co. for an additional 8 MW currently in the approval process with the state Public Utilities Commission, Kaleikini said.

DOH: No further environmental review needed for PGV permit

An aerial view of Puna Geothermal Venture from Feb. 15, 2019.

Puna Geothermal Venture — which hopes to produce electricity again by the end of the month following delays in rebuilding the facility after it was partially destroyed by lava two years ago — has cleared a hurdle in renewing its air pollution control permit from the state.

The Department of Health determined the state’s only geothermal power plant isn’t required to undergo additional environmental review in its ongoing permit renewal process. The so-called noncovered source permit requires renewal every five years.

“The DOH has taken a hard look at all the environmental factors raised in … demands for (environmental review), and it has concluded independently that a new or supplemental environmental review is not required to be conducted by the DOH for renewal … ,” wrote Bruce Anderson, state health director, in a letter to PGV and numerous opponents dated Sept. 4.

Those opponents include Puna Pono Alliance and Malama O Puna.

The state Department of Land and Natural Resources on Sept. 8, 2019, denied a request for environmental review by Pele Defense Fund.

OrmatPGV, which is owned by Nevada-based parent company Ormat Technologies Inc., supplied 31% of electricity to Hawaii Island before its shutdown.

Lava from the Kilauea volcano eruption that began in May 2018 isolated or covered the 38-megawatt power plant’s geothermal wells, destroyed the company’s substation and cut off the access road to the facility.

Asked Wednesday if the goal remains for going online by the end of September, Mike Kaleikini, PGV’s senior director said, “We’re still working on it.”

“We wanted to come online earlier, but the closer we got to the time, there was more work that needed to be done,” said Kaleikini. “Our target is still the end of the month, until such time something else might pop up or whatever.”

Mike Kaleikini

Company officials hoped PGV would be operational by the end of 2019 so the plant could sell electricity to Hawaiian Electric Co. early this year. But equipment problems and permitting issues kept that from happening. According to company officials, the coronavirus pandemic also was a factor.

Kaleikini said the company plans to get the smallest of its generation units, which produces 3 megawatts of power, online by the end of the month.

“That would be, probably, the initial startup amount, at the most,” he said. “Our plan has been, and continues to be, that we want to ramp up, and we’re targeting about 29 megawatts by the end of the year. That’s our estimates. But, hopefully, we can go higher than that.”

Work will continue to restore capacity to 38 megawatts, Kaleikini said. He noted there is an amended power purchase agreement with HECO for eight additional megawatts going through the approval process with the state Public Utilities Commission.

Those in opposition to the amended power purchase agreement include parties that sought environmental review of the project.

U.S. Rep. Tulsi Gabbard of Hawaii visited Unalaska in late August in her capacity as a major in the U.S. Army Reserve. … She said she’s excited about the opportunity for geothermal as a clean, renewable source of energy for Unalaska.

“I come from an island state in Hawaii. So I understand uniquely the food security and energy security challenges that exist when you live on an island, where you have maybe five to seven days of food supply at any given time, and where you’re reliant on external sources for energy,” said Gabbard. “The opportunity allows you to increase your food security through being able to power greenhouses and allows you to grow food here year-round. And it’s also directly tied into the security component of this island chain being centrally located in the Arctic region that is now becoming more and more active.”

VIDEO: Puna Geothermal Officials Take Questions Online

Puna Geothermal Venture plans to restart initial power generation in September. On Wednesday, company officials met with the community online.

Puna Geothermal Venture Video Conference Mike Michael Kaleikini Jordan HaraIn-person community outreach meetings were cancelled back in March due to the COVID-19 pandemic.

“We are happy to provide our community the opportunity to hear updates and give feedback in a safe format that respects shelter-at-home guidelines,” said Michael Kaleikini, Ormat’s senior director of Hawaii Affairs, in a media release. PGV is an Ormat subsidiary. “We are thankful for the support of our community as we rebuild and prepare to relaunch our operations,” he added.

The online session including questions and answers from the community. Here are some notes from the session:

Most of the questions came from Cory Harden, who is a member of the Sierra Club Hawai’i Island Group (correction: the name “Moku Loa Group” has been changed to “Hawaiʻi Island Group”).

When asked about their emergency response plans, the PGV reps said they “have changed a few items” in the plan, but “as for plugging production and injection wells” and removing pentane, Hara said nothing has been changed since the eruption. “We followed everything to the T,” he said.

There are no plans for hydrogen production at the plant at this time, Hara said.

When Harden asked if PGV will do “enhanced geothermal, adding water to create steam”, Hara answered: “Nope, never have, and we do not intend to.”

Hara said PGV has not drilled a new injection well yet, but they are “looking at potentially one or two more in anticipation for our production.” Kaleikini said although there are new injection wells identified in the application for an underground injection control permit with the EPA, PGV “will only drill a new injection well when it’s needed.”

Kaleikini said PGV has all the permits necessary to restart the facility, however they “are going through a renewal for the injection wells with the EPA”. Existing permits are in force.

Prior to the eruption, PGV was re-injecting about 3,000 gallons per minute (gpm), Kaleikini said. Plant manager Hara added that it was equivalent to about 100 gpm per megawatt. When the plant restarts, they do not anticipate the re-injection rate will be much more than that. “It will be less”, Kaleikini said.

On noise mitigation, Hara and Kaleikini said PGV put up external sound blankets and uses sound walls on the production side. An acoustical engineer has been hired to do a survey, and when they get back to full production, PGV will do another sound survey.

When asked about the location of production well Kapoho State 18, or KS-18, Kaleikini said it is “to the east of well pad E, which is right next to KS-14.”

Work on KS-18 has been completed, they said. They are now working on KS-17.

Paul Kuykendall noted that PGV’s application refers to geological studies that are 30 years old, and asked how is that relevant after the lava flow? “We do not anticipate the geology to be any different than when we originally started operations here in 1991,” Kaleikini said, “and we’re basing that on the preliminary data that we have received from our new wells and the reworking of our existing production wells.”

Harden noted that the hearing on the renewal of the EPA UIC permit is October 7th.

Kaleikini said PGV does not have a waiver from competitive bidding, in answer to a question that was perhaps in reference to a recent Hawaiʻi Public Utilities decision regarding Hu Honua bioenergy in Pepeʻekeo.

When asked if PGV plans to do a new Environmental Assessment or Environmental Impact Statement, Kaleikini answered: “We have not performed an EA or EIS, post lava eruption. We have looked into it in great detail, and our position at this time is that we will not be doing one.”

Officials said they hoped the Big Island plant would be operational by the end of 2019 so electricity could be sold again early in 2020. But the facility experienced equipment problems and permitting issues when attempting to come back online.

COVID-19 also hampered the work, the company said.

Puna Geothermal supplied 31% of electricity on Hawaii island before the shutdown.

After restarting, the company expects to gradually ramp up to produce 29 MW of power by the end of the year while work continues to restore capacity to 38 MW.

The company plans to expand the plant’s full capacity by another 8 MW in 2022.

Hawaii island’s geothermal power plant is slated to start producing electricity again by month’s end after prior delays to rebuild the facility that was partially destroyed by lava in 2018.

Puna Geothermal Venture announced the planned restart last week and also said it will host virtual community meetings to provide operational updates along with other information and to answer questions from the public.

The company, which canceled in-person meetings in March due to the coronavirus pandemic, has scheduled its first online meeting Wednesday followed by another one Nov. 11.

Meetings will be at punageothermalproject.com and start at 4 p.m.

Puna Geothermal Venture lava 2018 Kilauea eruption
Lava from Kilauea volcano flowed near Puna Geothermal Venture power plant in Pahoa on June 10, 2018.

The meetings also will be recorded and notes will be posted on the website along with continuing weekly project updates. Residents with questions or concerns may also call 369-9094.

PGV’s 38-megawatt power plant in Puna went offline in May 2018 when lava from Kilauea covered three out of several geothermal wellheads, monitoring wells, an electrical substation and a drilling rig in a warehouse. Lava also cut off road access to the plant and burned down transmission lines during the eruption that also claimed roughly 700 homes, farms and scenic recreational areas.

Since then, the company owned by Nevada-based Ormat Technologies Inc. has been working to restore operations. That work was delayed by permitting issues that pushed back prior expectations to resume power production by the end of last year. COVID-19 also hampered work.

OrmatBefore the shutdown, PGV was supplying 31% of electricity on Hawaii island. The company said it expects to restart energy production between the middle and end of this month, and gradually ramp up to produce 29 megawatts of power by the end of the year while work continues to restore more generation capacity.

Last month, Ormat reported that it had completed drilling two new production wells, though one was blocked after a flow test, and that more well drilling work would continue.

The company also intends to expand the plant’s 38-megawatt capacity by 8 megawatts in 2022.

PGV began operating in 1992 and has long been opposed by many nearby residents, in part because of concerns over potential release of hydrogen sulfide or other potentially dangerous volcanic gases.

Michael Kaleikini, Ormat’s senior director of Hawaii affairs, said the company is thankful for community support to restore operations and wants to keep area residents informed.

“We are happy to provide our community the opportunity to hear updates and give feedback in a safe format that respects shelter-at-home guidelines,” he said in a statement.

Ormat reports Q2 2020 financial results

OrmatThe parent company of Puna Geothermal Venture (PGV), Ormat Technologies released its financial results for the second quarter of 2020 with additional details on its business in an investor call. Reportedly, Ormat made significant progress to bring the Puna geothermal power plant on Hawaii online. Ormat’s updates on PGV during the investor call include the following:

PGV’s recent developments:

TNG Energy Services recently assisted with installing a new wellhead, centralizer, and pack-off at Puna Geothermal Venture.

As of August 2020, Ormat continue its efforts to recommission its Puna power plant. The Company obtained all necessary permits to start operation, completed the construction of the substation and connected a new production well to the power plant. We expect to resume commercial operation during the fourth quarter with gradual increase of generation to 29MW by the end of the year, subject to on time completion of the transmission line by HELCO and additional field recovery work.

The construction of the substation was completed by Ormat with the local utility HELCO as offtaker now having to complete their part for the grid connection, which is expected in Q3 2020. The drilling of two production wells was completed, while one well blocked after flow test, one is a successful well. Cleanout and drilling of new wells continues.

Initial power generation is now expected to begin in Q4 2020 with gradual operation of 29 MW by the end of the year, all under the assumption that transmission line upgrades and field recovery is successfully achieved.

Financial Highlight Regarding PGV:

… The Company recorded business interruption insurance income of $3.3 million related to the 2018 volcanic eruption in Hawaii, which netted to zero Puna’s cost of revenues and reduced general and administrative costs by $0.6 million; In the second quarter 2019, the Company recorded business interruption insurance income of $6.8 million that resulted in a positive gross margin of $1.8 million.

Comments by CEO Doron Blachar:

This was another solid quarter of strong execution led by the improved profitably of our Electricity segment. I am extremely proud of how our team is operating through the challenging COVID-19 environment and how we were able to successfully complete the enhancement of our 19MW Steamboat Hills complex on time and make significant progress to bring Puna back online by the end of the year.

As part of our efforts to disseminate legacy data and preserve the history of geothermal energy in Hawaii, we made an information page about the Scientific Observation Hole (SOH):

A geothermal experiment proved that the Kilauea East Rift Zone held geothermal potential. From 1990 to 1991, the Scientific Observation Hole (SOH) program operated three geothermal test wells in Puna, Hawaii. The data showed that a ten-mile interval along the Kilauea East Rift Zone held favorable high temperatures.

This page contains a brief history of SOH and links to relevant reports and data.

Diversifying Hawaii’s Economy

Kayte Jones, the author of the commentary

Hawaii local Kayte Jones suggests developing the local geothermal energy industry as a way to invest in our own communities, residents, and industries.

We should continue to attract tourists and profit from it, but we should not be completely dependent on it. It’s time to shift our focus. Don’t we have more to offer than the exploitation of our land, people and culture? Couldn’t we be a model of sustainability for the future through research of our unique ecosystem and climate? Through developments in agriculture and green energy like solar power, wind power, algae farms and geothermal energy? Couldn’t we be an educational destination through investment and development into our university system?

From Civil Beat: Manini Beach Park at Kealakekua Bay on the Kona side of Hawaii island. The Big Island lacks the infrastructure of Oahu, even though it needs help.

Hawaii’s climate also creates a unique opportunity for our state to be a model of sustainability via research and development into sustainable sources of energy, such as solar power, wind farms, geothermal and algae farms. The University of Hawaii is a land-, sea- and space- grant institution recognized as a research university. Investing in research and education can make Hawaii an educational destination.
