Are Undersea Cables to Transmit Electricity Feasible?

As I continue to look at ways to decrease our reliance on fossil fuels for our electricity generation so we will be free from the volatility of oil prices – particularly in this time where we know most of the “cheap oil” has already been found and processed, and global demand for oil exceeds its supply – I keep bumping up against the idea of undersea cables.

People are always questioning whether undersea cables are technologically feasible, and I thought you’d be interested to know that there at least 14 such undersea cables in operation today, transmitting electricity.

Some were built as far back as 1965, such as the Cook Strait submarine cables in New Zealand, which transmit electricity between the North and South Islands.

There is a very interesting history of the debate that went on in New Zealand before the cables were installed. What struck me is that the debate was in the 1950s and 1960s.

Some very modern cables have just been commissioned, such as the BritNed cable that connects the United Kingdom to the Netherlands and can transmit up to 1000MW. A short video on the BritNed web site details the making and laying of this cable.

Cables are currently being manufactured to be laid at depths up to 2000 meters, which is deeper than our Alenuihaha Channel (1900 meters) between the Big Island and Maui.

People used to believe that undersea cables couldn’t work in Hawai‘i because our channels are too deep. Undersea cables are clearly not the whole answer to Hawai‘i getting off of fossil fuels, but perhaps they can be part of a broad solution.

I am glad to know that the technology exists today, should we, the people of Hawai‘i, decide we want to share the robust renewable resources we have on each of our islands to create a reliable, stable, statewide electric grid that is not dependent on fossil fuels for its electricity generation.

About the Hawaii Island Economic Summit

On Friday, I attended the Kona/Kohala Chamber of Commerce’s Hawai‘i Island Economic Summit.

One of the questions during an energy session I attended was whether Big Island Mayor Billy Kenoi’s vision of “100 percent renewable energy by 2015” is reasonable.

I replied with some facts:

  • Puna Geothermal Venture (PGV) estimates that it has 200MW of geothermal power at its present site.
  • At peak use, the Big Island uses less than 200MW.
  • Right now, PGV is authorized to produce 60MW.
  • Last time it took them just six months to get authorization from the Planning Commission.
  • That would leave three and a half months for building the needed production units.

This is doable. What we need is the will to do it.

A description of the Economic Summit:

This Summit will consist of a morning panel “conversation” comprised of five to six guest thinkers and leaders who will discuss their work, ideas that inspire them and what they see as the future for Hawai‘i Island.  Confirmed speakers include Dr. Earl Bakken, engineer, businessman, philanthropist, inventor of the pacemaker; William P. Kenoi, Mayor of Hawai‘i County; Sanjeev Bhagowalia, Director of the newly created State Office of Information Management and Technology, Robert Pacheco, President and Naturalist Guide, Hawaii Forest & Trail and Michele Saito, President of Farmers Insurance Hawaii. Moderator for this panel will be Steven Petranik, editor of Hawaii Business magazine.

Our luncheon keynote speaker is Eric Saperston, acclaimed film director and producer, successful author and award-winning speaker and storyteller. Eric is Chief Creative Officer for the ‘inspire-tainment’ company, Live in Wonder, a forward thinking experiential company on the cutting edge of communication to ignite, inspire and enliven the world.

Eric’s story:

Dr. Earl Bakken talked about his manifesto (read about June and I visiting him at his request to discuss geothermal), which includes inspiring kids to use a live cam during the building of the Thirty Meter Telescope, the development of geothermal and Ku‘oko‘a, as well as building a world-class hospital in Waimea.

West Hawaii Today wrote about the summit.

What the Geothermal Working Group Found

Advantages of geothermal:

  • It is an indigenous resource
  • It generates revenue for the state
  • It generates community benefits
  • It provides stable power
  • It is less than half the cost of any of the renewable energy alternatives.
  • The Big Island will be over the geothermal “hot spot” for 500,000 to 1 million years

I want to share some highlights of the Geothermal Working Group’s final report.

IV. Recommended Steps for Hawaii State Legislators

– Make the allocation of geothermal royalties more transparent to show how benefits come back to the community. Designate the records of the allocations to be public domain.

– Establish a community advisory board to offer suggestions to the DLNR about how royalties generated by geothermal power plants are spent. The advisory board should be members of the communities that host existing or future geothermal power plants and/or those who are most impacted by the development of geothermal energy.

– Encourage the DLNR to use geothermal royalties to identify promising geothermal sites and to further develop the resource.

– In light of the probability that oil will reach $200 per barrel (Lloyds of London), the legislature is requested to commission a study to show the economic impact of various prices of oil.

– Facilitate development of geothermal with a critical review of the geothermal permitting process, regulatory capabilities, and possible investment incentives.

Page 5:

The Geothermal Working Group’s principal findings

– Geothermal is a renewable resource indigenous to the island of Hawaii that is dissociated from the price volatility of petroleum fuels.

– Geothermal can be a key component in a diversified energy portfolio for Hawaii County, both for the electrical grid and for transportation.

– In Hawaii, geothermal is a firm-energy resource at lower cost than fossil fuel. – Developing multiple geothermal plants is the most prudent approach.

– Geothermal has the potential to supply baseload electricity; long term reliability and the ability to supply grid management services (currently supplied by conventional fossil-fueled power plants) must be demonstrated in order to consider geothermal as the primary energy resource.

– With geothermal power plants, agricultural fertilizers, hydrogen, oxygen, and business-enterprise power can be produced for off-peak rates during the hours of curtailed electrical demand.

Page 9:

Overview

Geothermal energy can be developed to become the cheapest form of baseload power for Hawaii County. There are no importation or storage costs. Using geothermal as the primary source of baseload power will permit the county’s businesses to be more competitive with the rest of the world. Using geothermal as the primary source of baseload power will also help folks on the lowest rungs of the economic ladder—those who struggle with the cost of services.

In addition to stability and affordability, geothermal can leave less of an environmental impact than the commercially-available baseload power sources of electricity. There are no greenhouse gases, emissions and no oil spill risks.

The lower rates of off-peak geothermal electricity encourage the production of ammonia locally. Ammonia is an efficient hydrogen carrier that can be used to power internal combustion engines and as an aid to local agriculture as fertilizer. Light-industry business parks constructed near geothermal energy plants can use excess heat as a resource for heating vegetable and tropical flower hothouses, drying wood, and drying fish.

Benefits of geothermal energy to the community include sharing in geothermal royalties. In accordance with state law, the geothermal royalties are paid directly to the Department of Land and Natural Resources who allocate the royalties in three ways:

1. Department of Land and Natural Resources receives 50% 2. County of Hawaii receives 30% 3. Office of Hawaiian Affairs (OHA) receives 20%

Potential adverse impacts are listed below:

– Interference with worship of the Goddess Pele – Interference with certain Native Hawaiian practices – Rainforest destruction – Possible health and safety impacts – Disruption of the way of life for nearby residents – Hydrogen sulfide and other air quality issues – Noise – Increased strain on an inadequate infrastructure – Impact on native fauna and flora

If We Spend All Our Money on Electricity…

At a local level, the rising cost of electricity, whatever the cause, will result in severe economic pressures.

What’s important to realize is that 70 percent of our economy is based on consumer spending. “If people no more money, they no can spend.”

It all relates to costs.

It’s the southernmost island in the chain, however, that may be the most richly endowed overall, and the most promising resource of all is the one that’s buried far beneath the surface…. Read more

Having attended four Peak Oil conferences now, I have seen that Jeff Rubin is one of the credible commentators on the world oil situation. His comments are especially relevant to the discussion about rising oil prices in Hawai‘i today.

Audio of Jeff Rubin’s talk at the most recent ASPO conference.

From his blog:

…The real story behind triple digit oil prices is not the threat of supply shocks, but the sheer, unrelenting rise in world oil demand.  Already closing in on 90 million barrels a day, the quick rebound in world oil consumption to new record highs demonstrates the global economy can’t grow without burning greater amounts of oil.

No matter how many rabbits the oil industry can pull out of its hat, be it tar sands from Alberta or shale oil from the Bakkens, supply just can’t seem to keep pace – at least not at the prices most consumers can afford to pay. That is the message that triple digit prices keeps telling us.

If the global economic expansion, troubled as it may be, continues, we will see even higher oil prices in 2012. But what does that say about the sustainability of growth?

And even if there is growth, what is the pace? Read the whole post here.

Jeff Rubin explains why he quit his job as Chief Economist at CIBC World Markets. In Hawai‘i, we call it kuleana.

After twenty years as Chief Economist for a North American investment bank, it was time for me to seek a larger audience for the story I needed to tell.

My predictions of steadily rising oil prices over the last decade, including my call for $100-per-barrel oil by 2007, had flown in the face of conventional wisdom.

Among other things, my track record on predicting rising oil prices demonstrated that the traditional laws of supply and demand were no longer working for one of the economy’s most basic and essential commodities. And when they stopped working, the consequences for the economy would be severe.

It wasn’t subprime mortgages but triple-digit oil prices that brought down the world economy.

And unless that economy started to wean itself off an ever-depleting supply of affordable oil, there would be other recessions to follow as economic recoveries would simply push oil prices right back into triple-digit range. But weaning our economy off oil meant, at the same time, making fundamental changes in the way we live.

This is not the kind of message investment banks want their chief economists delivering these days, to either governments or investors. But the urgency of this message grows with every passing day.

On March 31, 2009, I resigned my position as Chief Economist and Managing Director of CIBC World Markets to deliver this message in my book, Why Your World Is About To Get A Whole Lot Smaller: Oil and the End of Globalization.

Jeff Rubin was the Chief Economist at CIBC World Markets for 20 years. He was one of the first economists to accurately predict soaring oil prices back in 2000 and is now one of the world’s most sought-after energy experts. He lives in Toronto.

Mayor Kenoi Announces Hawaii County Will Use 100% Renewable Energy by 2015

At the press conference announcing the Geothermal Working Group’s final report, Mayor Billy Kenoi announced that Hawai‘i County will use 100 percent renewable energy by 2015. That was significant.

Mayor Kenoi emphasized geothermal’s primary role as that of base load and he said we are lucky to have an array of options available, such as wind, solar and biomass. He mentioned that the County would be converting some of its passenger vehicle fleet to electrical. He said that we will need the help of the Federal, State and County governments, as well as that of the community.

He has already touched bases with Lieutenant Governor Shatz, and will be speaking with our congressional delegation next week. Senator Kahele and Representative Nakashima both reiterated the importance of enabling geothermal for base power.

Hawaii 24/7: Geothermal Working Group Presents Findings

Although the topic of the press conference was the Geothermal Working Group’s final report, Mayor Kenoi’s announcement about taking the Big Island to 100 percent renewable energy by 2015 was the big news.

He is retaining the Geothermal Working Group, which will continue its work under the County of Hawai‘i.

As I have been saying, we are running out of time. Mahalo, Mayor Kenoi, for leading the Big Island to a safe place for us and future generations.

Following the Mayor’s lead, we can get there. Not, no can. CAN!

Geothermal Working Group Report is Unveiled

We know the era of cheap oil is over, and that it is only a matter of when and how high oil prices will rise.

What we need now is to see what we can do to enable geothermal. Two-thirds of our economy is made up of consumer spending, and stabilizing electricity prices will help our people cope.

From Hawaii Reporter:

Geothermal Working Group- Final Report unveiled by the County of Hawai‘i

REPORT FROM HAWAII COUNTY – HILO, HAWAII – The Geothermal Working Group, with the support of Hawai`i County Mayor Billy Kenoi, will present the final draft of the Geothermal Working Group Report on Wednesday, January 4, 2011 at 2:30 p.m.  The press conference will be held at the County building on the Mayor’s lanai at 25 Aupuni St., second floor.

The report was sponsored by the County of Hawai‘i to evaluate geothermal energy as the primary source of baseload power for electricity on the Island of Hawai‘i.  The report includes an analysis of technical data and expert testimony providing convincing rationale to develop local renewable energy plants and transition away from the county’s dependence on petroleum-fueled generators for baseload electricity.  The report, which is currently being circulated within Hawai`i’s State Legislation, was developed as research to help support Hawai`i’s Clean Energy Initiative goals…. Read the rest

2011: The Year in Review

What a year it’s been! Here are some 2011 highlights:

There was a lot of conversation, of course, about geothermal. The Geothermal Working Group Interim Report  – which provided lawmakers with an evaluation of using the hot water reservoir in certain locations of Big Island to provide local and renewable energy for electricity and transportation – was distributed to state legislators. I also wrote about it being a matter of leadership, about mopping the deck of the Titanic, and about how the momentum toward geothermal has shifted. Also about a Democratic Party Resolution supporting geothermal for baseload electrical power.

I attended a geothermal energy forum in Pahoa, with Hawaiian leaders speaking and every seat taken. There were more Hawaiian perspectives in supporting geothermal, this time in Hilo. And about even more Big Island support for geothermal.

People seemed to enjoy the conclusion of my Maku‘u Series. I got a lot of great feedback on it. It was fun remembering the old days and the old ways of my Kamahele ‘ohana in Maku‘u.

I wrote about biofuels, and the very real problems with them. Also on biofuels and feedstock. I wrote a post about the National Research Council calling biofuels costly and their impacts questionable.

I spoke to the Kamehameha Schools First Nation Fellows about food sustainability, showed them the farm and gave them some of the best advice I could think of.

Of course I mentioned a few times about how “If the farmers make money, farmers will farm.” That link is to one of those times.

In June, seven Polynesian-style voyaging waka (canoes), representing different Pacific Islands, arrived in Hilo Bay after a two-month voyage from Aotearoa (New Zealand).

Leslie Lang, my blog editor, went for a spin around the bay on one, and we wrote about how the ancient ways are again showing us the way.

“It’s all about taking the knowledge and wisdom of the past and using it in the present to make a stronger future. It’s exactly what the old Polynesians did when they sailed out into the Pacific to find new land.”

It’s a strong metaphor. I wrote my impressions of the vaka here.

Oahu’s Electricity Rates Surpass Other Islands

It used to be that the avoided cost (the part of your electricity bill that is due to oil) was higher on the other islands than on O‘ahu. This Hawaiian Electric (HECO) chart shows the rate on different islands back to 2008.

This past October, though, the avoided cost on O‘ahu, Maui and Hawai‘i Island was roughly the same, at approximately 15 cents per kwhr.

Now, O‘ahu’s avoided cost has about doubled. It’s 29 cents per kwhr now, and actually higher than on the other islands.

This is more proof of what has been clear to me since 2007, when I attended my first Peak Oil conference – that oil prices were going to just keep rising.

Avoided costs for January 2012: 

HECO (O‘ahu)

On Peak 29.167 cents per kwhr

Off Peak 19.060 cents per kwhr

HELCO (Big Island)

On Peak 21.656 cents per kwhr

Off Peak 17.656 cents per kwhr

MECO (Maui)

On Peak 20.240 cents per kwhr

Off Peak 19.194 cents per kwhr

MECO (Lana‘i)

On Peak 34.621 cents per kwhr

Off Peak 29.057 cents per kwhr

MECO (Moloka‘i)

On Peak 29.428 cents per kwhr

Off Peak 26.580 cents per kwhr

Democratic Party Resolution Supports Geothermal for Baseload Electrical Power

The following is a resolution that the Hawaii County Democratic Party adopted at its 2011 County Convention. It recognizes the value of geothermal as an indigenous resource, and it recognizes that low cost is a relevant and important aspect that benefits society.

It also notes that the EPA has directed the HECO companies to retrofit its oil-fired plants to comply with emission standards. But that will cause oil-fired plants to stay in operation longer than desirable, and will result in higher cost to ratepayers.

Note especially this:

“NOW THEREFORE BE IT RESOLVED THAT the Hawai‘i County Committee of the Democratic Party of Hawai‘i hereby formally requests the 2012 Hawai‘i State Legislature to direct the Public Utilities Commission to require HELCO to develop a timely plan to retire its fully depreciated fossil fuel power generation facilities and accept geothermally generated electrical power as the primary baseload source. HELCO should continue to include other alternative energy sources – such as wind, solar and hydro – in its mix of sources, but geothermally generated electricity must become the primary baseload source for Hawai‘i Island within the next five years; and

FURTHER BE IT RESOLVED THAT the PUC should continue to implement contractual procedures between HELCO and geothermal power producers that represent an equitable return on investment but, as important, reduce the kilowatt hour cost to consumers whenever possible.”

The Resolution:

Requesting the 2012 Legislature to Mandate PUC to Require HELCO to Develop A Timely Action Plan To Retire All Depreciated Oil-Fired Power Plants on Hawai’i Island And Transition to Geothermally Generated Electricity As the Island’s Primary Baseload Power Source

WHEREAS, the Hawai‘i County Democratic Party adopted a resolution at its 2011 County Convention supporting the use of indigenous, renewable geothermal energy to generate baseload electrical power to (1) reduce dependency of imported fossil fuels, (2) reduce our carbon footprint and other environmental risks, and (3) hold the line or reduce electrical energy costs to consumers; and

WHEREAS, Puna Geothermal Venture has proven the safety and reliability of geothermally generated electrical power for Hawai‘i Island consumers for about 18 years; and

WHEREAS, this geothermal power has also generated royalty payments to the State and County of Hawai‘i and the Office of Hawaiian Affairs running in the millions of dollars over the past 18 years; and

WHEREAS, the Public Utilities Commission has in the past year initiated new contractual procedures between HELCO and PGV which are successfully reducing the kilowatt hour cost of geothermally generated power to consumers; and

WHEREAS, all but one of HELCO’s existing fossil fuel-dependent power generation facilities on Hawai‘i Island are fully depreciated but continue to be operated, which has destructive environmental and economic consequences, including forcing Hawai‘i Island consumers to pay the highest kilowatt hour charge in the state – a cost that will continue to increase as the global peak oil situation further drives up the cost of fossil fuel;

WHEREAS, the federal Environmental Protection Agency has recently directed all HEI companies including HELCO to retrofit existing oil fired plants to comply with EPA emission standards. This expensive undertaking will force continued usage of these plants and perpetuate a level of emissions and kilowatt hour costs that exceed that of geothermal. Also, this investment – which will inevitably be borne by consumers – should, instead, be dedicated to the transition to environmentally and economically preferred geothermal power production and/or distribution;

NOW THEREFORE BE IT RESOLVED THAT the Hawai‘i County Committee of the Democratic Party of Hawai‘i hereby formally requests the 2012 Hawai‘i State Legislature to direct the Public Utilities Commission to require HELCO to develop a timely plan to retire its fully depreciated fossil fuel power generation facilities and accept geothermally generated electrical power as the primary baseload source. HELCO should continue to include other alternative energy sources – such as wind, solar and hydro – in its mix of sources, but geothermally generated electricity must become the primary baseload source for Hawai‘i Island within the next five years; and

FURTHER BE IT RESOLVED THAT the PUC should continue to implement contractual procedures between HELCO and geothermal power producers that represent an equitable return on investment but, as important, reduce the kilowatt hour cost to consumers whenever possible.
