Can Our Waterways Provide a New Source of Baseload Power?

Virginia is the first state to formally press for the creation of a virtual power plant. Glenn Youngkin, the state’s Republican governor, signed the Community Energy Act on May 2, which mandates Dominion Energy to launch a 450-megawatt virtual power plant (VPP) pilot program.

Virginia isn’t alone in this endeavor, but it is certainly the most out front. There are many incipient VPPs clustered around utilities across the country.

A virtual power plant is the ultimate realization of something that has been going on for a long time as utilities have been hooking up various power sources, managed conservation and underused generation, known as distributed energy resources (DER). These, according to even small utilities, can contribute up to and possibly over 10 percent electricity to a utility system.

Organized and formalized and with enough coverage, DER becomes a VPP. Sometimes the terms are used interchangeably.

A virtual power plant not only depends on managed conservation and underused generation but also on some imaginative use of resources, like hooking up transportation fleets to discharge their batteries onto the grid when they aren’t in use. Electric school buses are frequently cited as playing a role in future VPPs. Conservation and solar roofs with related batteries are the backbone of DER and VPPs. Eventually, they are expected to be common to most utilities or consortia of utilities.

In Owings Mills, Maryland, an engineer and inventor with a slew of patents to his name, Key Han, dreams of a different kind of VPP, one which could, if widely deployed, provide a new source of baseload power.

Han, CEO and chief scientist at DDMotion, has pioneered speed-converter technology which, if widely deployed, would produce inexpensive, reliable energy in sufficient quantity to be described as baseload. Indeed, he said in an interview, “It would be a huge new source of baseload.”

Han’s technology converts variable energy inputs into constant speed outputs. For example, the flow of water in a stream is variable but with his speed-converter  technology, the energy in the flow can be captured and converted to a constant speed output.

With his technology, grid-quality frequency can flow from many sources without extensive civil engineering or major construction, he told me. In particular, Han cited non-power dams, like the ones in New England which were built in the 19th century to drive the textile mills.

“A simple harnessing module with a generator behind the spillway coupled with my technology can produce frequency that is constant and ready to go on the grid. If you have enough of these simple, low-cost generators installed, you have created a new baseload source, a virtual power plant of a different and exceptionally reliable kind,” Han said.

Another use of the same DDMotion technology would remedy what is becoming a growing problem for wind and solar generators: the lack of rotating inertia. Inertia is essential for utility operators to fix sudden changes in frequency caused by changes in generation or consumption (50 cycles in Europe and 60 cycles in the United States).

Lack of inertia has been blamed for the widespread blackout on the Iberian Peninsula and is becoming an issue for utilities with a lot of solar and wind generation, so called inverter power. This refers to the grooming with an inverter to power to grid-quality alternating current from its original direct current.

Here, again, his technology can inexpensively resolve the inertia problem for wind and solar generation, Han said. Either using a mechanical system or an electronic one, wind and solar systems could provide rotating inertia.

Increasingly, utilities are looking for untapped sources of power which can be bundled together into VPPs.

Renew Home, a Google-financed company, claims 3 gigawatts of electricity savings, which it says makes it the leader in VPPs. It relies on managing end-use load primarily in homes with load shedding of high energy-consuming devices during peaks. This is accomplished by using special thermostats and smart meters.

Industry experts believe artificial intelligence will be a key to extracting the most energy out of unconventional sources as well as fine tuning usage.

VPPs are here and many more are coming.

When the Light Fails — Modern Society’s Weakest Link

Modern life has a woven-in thread of vulnerability that is peculiar to our times: electricity. It is the cardiovascular and nervous system of life across the world, more so in the Internet Age than even 30 years ago.

If the nation were to lose electricity, it would cause an instant and lethal paralysis that would go beyond inconvenience of the kind parts of New England have just experienced — and that left me charging my cell phone in my car.

Nonetheless, limited and scattered blackouts of the kind I have been caught in are a reminder of what alarmists (alarmists are unsettling, but not always wrong) have been warning. If there is no electricity, there is no light, no water, no sewage treatment, no gas and diesel, no heating and cooling — even gas and oil systems rely on electric pumps and fans. If such a blackout were sustained, slow death through starvation, or fast death through disease and armed gangs ravaging the cities and towns for food, would be the result.

A curtain-raiser is Puerto Rico. Just look to its agony: The mitigation is that there is help from the rest of the United States — imperfect and maybe inadequate, but still help.

In a national blackout, Canada and Mexico might be as affected, and the catastrophe would be complete.

Such a blackout — very unlikely but not inconceivable — is posited to come from a hostile power using a nuclear weapon targeting the special vulnerability that comes with electricity and computerization. The hostile power would not target cities, as in the past, but instead would detonate a nuclear bomb high in the atmosphere, creating an electromagnetic pulse (EMP), which would do the damage. It would cause destructive electric surges, fry electronics and render most things that support daily life in 2017 inoperable.

The phenomenon has been known since the earliest days of nuclear weapons development, during the World War II Manhattan Project. Atmospheric tests by both the United States and the Soviet Union in 1962 gave the world hard evidence. The new urgency comes because some believe North Korea would try such an assault as soon as it perfects its long-range intercontinental missile.

One of the people who takes the EMP threat seriously is nuclear proponent and public policy advocate Richard McPherson of Idaho. He has written to President Trump proposing that Puerto Rico become a test bed for an EMP-hardened electrical grid.

Engineers believe they know how to do this, but the cost would be prohibitive, according to experts I have interviewed at the Electric Power Research Institute and the Edison Electric Institute, respectively the research arm of the electric industry and its trade association.

Robin Manning, EPRI vice president of transmission and distribution infrastructure, says they are studying the EMPs and a progress report is expected in a few weeks.

To believe the North Korean theory, you have to accept that North Korea is run entirely by cartoonish characters like its president, Kim Jong-un, and that they wish to be destroyed in global retaliation, from Europe and even China.

A quieter and very knowledgeable voice comes from Siegfried Hecker, a former director of the Los Alamos National Laboratory. He has visited North Korea’s nuclear sites seven times and has seen some of their most secret installations, including their centrifuges. He has even been allowed to handle a container of plutonium, the raw material of thermonuclear devices.

In a speech at Brown University on Oct. 31, Hecker said that North Korean technology and science is very impressive, and the scientists and engineers running the nuclear program are not mad fanatics but very dedicated to their task. He does not see the small country as an existential threat to the United States, but it is a problem: a problem that must be tackled civilly, through conversation.

“We know nothing about this country and who controls their nuclear arsenal. We need to talk to them, and their denuclearization will come later,” Hecker said.

Meanwhile the long-term security of the electric system remains a national necessity, whether the threat is monster storms, cyberattack or EMPs.

Scott Aaronson, EEI executive director of security and business continuity, says a “holistic” approach for security, embracing all hypothetical disasters, not obsessing on one, is necessary.

The situation in Puerto Rico is not hypothetical. It is an American tragedy of enormous proportions here and now. It is also a frightening window into what can go wrong in this, the Electric Century.

Whoosh! The Electric Car Is Rolling into American Life

U.S. transportation is about to get a mighty electric shock.

The days of the internal combustion engine are numbered. The electric car is about to do to the traditional gasoline and diesel car engine what the cell phone is doing to the copper-wire, landline telephone: shoulder it out of the way.

Andrew Paterson, a principal with the Verdigris Capital Group, told a conference in Washington on June 7, electric car sales will at least quadruple in the coming decade and then really begin to accelerate. This, he said, was part of a larger electric boom that would see the doubling of world electric demand, mostly in Asia, by the middle of the century.

Electric utilities in the United States stand to benefit from the switch from gasoline and diesel to electricity largely because they will be able to meet the new demand without adding new generation, according to the Electric Power Research Institute in Palo Alto, Calif. It believes most of the charging of electric vehicles will take place off-peak, at night and when there is less demand. At worst the new load will fall partly during the day, when there is a surplus of solar power.

Analysts say much depends on whether commercial and company parking facilities can be turned into charging stations as well. Maybe when the boom really picks up, even parking meters will become charging stations.

The change in transportation will have huge effects beyond the car infrastructure. Gradually, gas stations will become obsolete. Technicians who service cars with oil changes and tuning will be out of work.

Electric cars are fundamentally simpler than today’s vehicles — they will run for tens of thousands of miles without maintenance, and that will be confined to things like tires, brakes and lights. Cities will get cleaner and quieter.

Once upon a time, it was just environmentalists who loved electric cars. Now consumers are gooey over them. The proud owner of a Tesla Model S told me this week that he would never buy a conventional car again. He said his Tesla has it all — quiet, undreamed of acceleration and great luxury. And he has what it takes to go electric easily: a suburban home with a carport and a charging station in his office building in Washington.

Apartment dwellers and those without driveways or garages in townhouses will have to wait for technology to fix their charging needs. Manufacturers are striving for easier charging and longer-endurance batteries.

There are, by my count, less than a dozen dedicated charging companies that have sought to commercialize charging by wiring commercial garages and other places where cars sit. None has been very successful to date and there have been bankruptcies.

As always with new ways of doing things, there is hesitance and a hope that someone else will lead the way. I believe that the moment entrepreneurs find a way of making money from cars in commercial parking lots and other away-from-home sites, there will be a boom in offering charging and the switch to electric will be accelerated. Charging will become big business.

But questions do abound for long-distance driving. Soon 300 miles will be the electric vehicle standard, but it will not get you from Chicago to Los Angeles, or even Washington to Boston.

The speed of technological evolution is the unknown, but it will control the accelerator in the race to electricity. Better batteries, faster charging and more public confidence in the duration of each charge will all control the rate of change.

When it comes to heavy vehicles that travel great distances, like intercity buses and trucks, the conversion to electricity, though yearned for, may be a lot slower. Until smart highways offer charging through induction, using electromagnetic fields, diesel will still rule.

The earliest cars were electric and were thought then to be the future — clean and quiet. But lead-acid batteries could not hack it. Stubbornly Harrods, the famous department store, used electric delivery vehicles around London until the 1960s; maybe because these sedate, quiet, liveried road queens exuded classiness.

Like all revolutions, there will be winners: those who find out how to make money out of battery charging and those who make electricity. And losers: oil companies, gas stations, service departments of dealerships and the long-dreamed-of hydrogen car.

Incontrovertibly, the air in cities will be a winner — a big, big winner.

Electricity Is the Gift That Can Keep on Giving in Africa

Photo: South Africa – August 24, 2014: African woman with child collecting water from the river on the road leading to local Game Reserve.

He is generic Africa Man. You can see him everywhere, walking barefoot across the Savannah and desert landscapes. He is on a mission that gets harder as time goes on.

His mission is to find enough wood — a few dry sticks here, some roots there — to make a fire for a hot meal and to bathe. He walks and walks, adding a stick and a piece of scrub wood to the bundle carried, in the traditional way, on his head.

Generic Africa Woman is busy, too. Her mission is to draw water. She carries a container on her head, filled with water from a distant well, to make dinner — a meal of maize (corn) porridge with maybe a stew of some meat or even caterpillar — and to bathe.

African life is picturesque, but it is not pretty. Hardship is in daily attendance in much of Africa, blighted from deforestation and polluted water.

Yet Western aid has not been easily delivered. Much of it has been stolen, some of it has been misapplied and some of it has led to aid dependency.

So, as an old Africa hand (I was born in what is now Zimbabwe, and left when I was 20 years old), I was elated to learn of a new and critical partnership just announced between the Edison Electric Institute (EEI) and the U.S. Department of State’s Power Africa initiative. Electricity anywhere is the gift that gives and gives, but especially when it begins to transform lives of hard struggle to ones that are less so.

When I was a boy, the opening of a power station or the building of a power line were events that brought forth celebration. Electricity signaled a better tomorrow.

When a village — whether it is in Bolivia, India or Uganda — is electrified, good things flow. A simple hotplate replaces days of firewood collection and those who can read can do so after the sun sets: hygiene improves, education is facilitated and expectations soar.

When the shantytowns that surround Johannesburg, South Africa, were electrified, the productivity of workers who flood into the city every day went up. Simply, they were saved from the drudgery of collecting animal droppings, wood scraps and other combustible stuff to burn.

The colonizers of Africa realized the need for electricity. Hence, in my part of the continent, two great dams were built on the Zambezi River: the Kariba, between Zimbabwe and Zambia, and the Cahora Bassa in Mozambique.

As a very young reporter, I covered the construction of the Kariba Dam, and its near destruction by unusually heavy flooding, in 1957. It has been the backbone of electricity supply for Zimbabwe and Zambia for more than 50 years.

But in recent years the dam, holding back the world’s largest, man-made impoundment of water, has begun to show deterioration in the concave wall, but especially behind the wall. The outflow has been eroding the plunge pool and threatening the wall. Hundreds of millions of dollars have had to be raised internationally for remediation, which is yet to begin in earnest. If the dam should fail, about 4 million people would die downstream.

The dam also has been producing much less electricity than it had been previously due to multi-year drought in the region. Copper production in Zambia, a vital industry, has had to be curtailed because of severe electric shortages. Blackouts are routine throughout the region.

Electricity is also a problem in South Africa, the industrial and commercial giant of Africa. Delay in ordering new generation, political interference in the decision processes and other problems, stemming from the end of apartheid, have damaged the system. Blackouts are affecting South Africa’s competitive posture.

Now the government is being romanced by Russia, hoping to sell it a new nuclear plant on favorable terms. It would join the two-unit, 1,860-MW Koeberg Nuclear Power Station, which has been operating since 1984. Unfortunately emerging countries have a fascination with big, showy projects, like the national airlines and steel mills that have cost them so dearly in their post-colonial phase.

EEI and the State Department need to guide the countries of Africa to today’s energy solutions, not yesterday’s. Africa needs to turn to its most abundant resource: sunshine. In North Africa, Morocco is building the world’s largest solar installation. Way to go.
