Future Of Grid: Smart

January 18th, 2012

This is a sample article from the January 2012 issue of EEnergy Informer.

Failure to meet the challenges facing the grid could be degraded reliability.

In the past few years, smart grid has risen to top of everyone’s favorite list of topics. Numerous studies and books are devoted to its many purported benefits, including one edited by this newsletter’s editor (see flyer). The latest on the subject is a report released in early December by the Massachusetts Institute of Technology (MIT).

Coming as part of a series of MIT reports looking at the future of coal, nuclear and everything else, this one is rather immodestly titled The Future of the Electric Grid. While comprehensive in scope, literally covering the A to Z of the smart grid, much of what it says has already been said elsewhere, but perhaps not in an integrated fashion – the report’s most significant plus.

Disjointed

Starting with an overview of the complex North American electricity infrastructure and even more complex array of stakeholders, regulators and others who have a say in how it is organized and operated, the MIT report points out just how disjointed it is. In the absence of a coherent federal policy and with so many overlapping organizations and players, it is a miracle that the grid operates as well as it does.

Adding to this maddening complexity is the existence of some 3,200 distribution entities, some private, others publicly, municipally or government owned, each operating under different set of rules and regulations – and some with little or no regulation or oversight.

Multiple stakeholders

As repeated in all other studies of the smart grid, the MIT report identifies the need to integrate massive amounts of new renewable generation as the “most significant challenge facing the grid.” Increased penetration of electric vehicles (EVs) is also highlighted as warranting special attention (chart below).

More EVs

A chapter titled Engaging Electricity Demand covers various promising options to increase customer demand-side participation (DSP) in electricity markets, broadly defined. This, needless to say, is also the topic of multiple other recent studies as increased attention is focused on manipulating and managing both the volume and pattern of energy consumption by influencing customer behavior.

Referring to recent studies conducted by the Federal Energy Regulatory Commission (FERC), the MIT report examines a number of pricing and behavioral schemes to reduce peak demand, with and without enabling technologies. Like other chapters, it provides a good overview of the issues plus useful references.

Reduce the peak

Among the report’s main conclusions is that FERC “should be granted enhanced authority to site major transmission facilities that cross state lines so as to make easier the integration of remote renewable,” a sensible recommendation but one that is easier said than done.

While FERC may welcome an “enhanced authority” to do more in transmission planning, routing, and pricing, not everyone in the industry would welcome such a thing. FERC’s proper role and reach, like those of other regulatory agencies, is controversial and hotly disputed. There are many among the stakeholders who would rather see a diminished, as opposed to an enhanced, level of authority for FERC.

The MIT report also recommends that, “utilities with advanced metering technology should begin a transition to pricing regimes in which customers pay rates that reflect the time-varying costs of supplying power.” English translation: introduce dynamic pricing once you are done with installing smart meters.

Different horses for different courses

Another sensible suggestion, but one that requires state-level regulatory approval at multiple states, each with their own priorities, set of rules and timetables. The problem is that glaciers move faster than most regulators.

Having identified the opportunities facing the industry it cautions that “failure to realize these opportunities could result in degraded reliability, significantly increased costs, and a failure to achieve several public policy goals.”

Keystone Pipeline: Postponing The Day Of Reckoning

December 19th, 2011

This is a sample article from the December 2011 issue of EEnergy Informer.

President Obama’s decision to delay controversial pipeline pleased no one.

By some estimates, Alberta’s tar sands may contain as much hydrocarbons as Saudi oil, and at $100 per barrel, there is an attractive margin to be had by eking the tar out of the sand. For some time, that has been the official policy of the province of Alberta, endorsed by the powers to be in Ottawa.

Mostly tar sand

Two minor problems, however, get in the way. First, it takes a lot of energy — mostly natural gas — and even more water to extract the heavy bitumen from the sand, even if we ignore the massive environmental costs. Second, land-locked Alberta is far from any major markets or refineries that can convert the heavy crude to something useful, such as gasoline, kerosene or diesel.

The first problem is not unique to Albertan tar sands but afflicts nearly all future sources and methods of oil extraction and production. The oil and gas business is gradually moving towards non-conventional, which generally means that it will get more energy-intensive, more expensive and more environmentally. The easy to reach oil and gas is a thing of the past.

In the case of Albertan tar sand oil, the second problem can be addressed by building massive pipelines that would transport the heavy crude to refineries in the south or ports to the west, hence the multitude of proposed pipelines shown in the map below.

Move it to the South, or failing that, to the West

Alberta’s eyes have always been fixed on the oil-thirsty US to the south. An existing pipeline built a few years ago, already delivers tar sand oil to Chicago, Illinois.

TransCanada Corp. has proposed a second 1,700-mile pipeline, the Keystone XL, to terminate at refineries near Houston & Port Arthur on the Gulf of Mexico. Because the pipeline crosses the border, the US State Department has the final say in allowing the project to proceed, which explains why it has turned into a major political issue amidst opposing sentiments ahead of the 2012 election season.

The powerful oil lobby on both sides of the border points out that the pipeline = jobs, in both countries, and this has enormous appeal given the currently high unemployment rate in the US. For its part, the environmental community has successfully turned the pipeline into a political flashpoint, a test of President Obama’s environmental resolve — and whether he can stand up to big oil. Canada, Alberta and TransCanada have been caught in an unpleasant and unwanted cross fire.

There is little dispute that the $7 billion pipeline will create jobs. Concerns about leaks can be dismissed as trivial. And in the grand scheme of things, the pipeline is not as critical or as devastating as either side has made it. In this newsletter’s view, at its core, the issue is whether the US should tie itself to Albertan tar sand oil that is viewed as more carbon-intensive than conventional oil and comes with significant environmental side-effects. The carbon-intensity issue, of course, is debatable, since all oil, no matter how it is extracted, shipped, refined, distributed and ultimately used is carbon-intensive.

Land locked and far from the market

At a time when the International Energy Agency (IEA) has declared the urgency of addressing climate change, some in the environmental community believe that the US should focus on using less oil, especially carbon-loaded type of oil, by concentrating on energy conservation and renewables. The recent requirement that US cars should get a minimum of 54.5 miles to the gallon by 2025 as opposed to a meager 29 today, would save more oil than the XL pipeline can carry. Such policies deliver better value and are less damaging to the environment than shipping tar sand oil 1,700 miles to refineries.

Moreover, with plentiful and cheap domestic shale gas — to be followed by shale oil — why bother with “dirty” tar sand oil pumped to the Gulf of Mexico? Tar sand oil is an outdated format, as in the Betamax of the bygone days of video industry, for those old enough to know what we are talking about.

Be it as it may, the environmental community was pleasantly surprised to find that the Keystone XL pipeline was resonating with its constituents, turning it into a full-blown political issue. Massive demonstrations were organized, including forming a human chain around the White House to bring the message directly to President Obama, who could not avoid seeing and hearing the protesters from the oval office. Activists and well-known celebrities chained themselves to the White House fence, had to be arrested and carried away — generating free publicity for the cause. It was incredibly effective.

To nearly everyone’s surprise, in mid November, the State Department announced that a decision on the project would be “delayed” until after the 2012 election to allow “further studies.” Kerri-Ann Jones, a State Department official emphasized that, “this is not a political decision,” adding that the White House had nothing to do with it. It merely reinforced the fact that it was indeed a highly political decision and that in all likelihood it had come from the very top. How could it be any other way? (See footnote).

A day prior to the “delay” announcement, Bob McKibben, a key figure in orchestrating the anti-pipeline protests, told Financial Times (9 Nov) that “The odds are still against us, because the oil industry has more money than God, but those odds are shortening” (emphasis added). By all accounts, the oil lobby outspent the environmentalists by a wide margin, boosted by heavy-handed pressure from Canadian politicians from Alberta and Ottawa. But it was to no avail. David defeated Goliath, at least in the first round.

Canadian Prime Minister, Stephen Harper, expressed disappointment following the “delay” decision, stating that, “My view …. hasn’t changed. President Obama has to make a decision,” while reiterating his hope that the project will be decided on its merits and eventually approved. TransCanada announced that it would re-route the pipeline to avoid crossing certain sensitive areas — seemingly oblivious to the fact that the issue is not the pipeline’s route or the potential leaks.

Big Oil Exporters

Alberta suffered another symbolic setback earlier in 2011 when the European Commission decided that under its revised fuel quality directive, the use of oil derived from tar sands should be discouraged because of its heavy carbon footprint.

EC’s decision gets messy since crude oil from various sources comes with varying amounts of carbon associated with extraction, transportation and energy used in the refining and final distribution process. How is a hapless consumer at the petrol pump to know what he or she is putting in the tank? That’s why economists favor transparent carbon taxes, avoiding EC-type decisions or the pointless debate about the TransCanada pipeline.

The reactions to the State Department’s “delay” decision were predictable. Jack Gerard, Director of the American Petroleum Institute (API), told The Wall Street Journal (11 Nov 2011) that, “This is clearly about politics and keeping a radical constituency opposed to any and all oil and gas development in the president’s camp for 2012.” Terry O’Sullivan, general president of the Laborers International Union of North America, representing the blue-collar workers, was quoted in the same article saying, “The administration chose to support environmentalists over jobs — job-killers win, American workers lose.” Susan Casey-Lefkowitz, representing the National Resources Defense Council (NRDC), praised the decision saying, “It doesn’t make sense for America to be building infrastructure for dirty oil for the next five decades.”

Albertan officials immediately began posturing that if America doesn’t want our oil, they will find other buyers in Asia. Ports in British Columbia are a fair distance away from the Albertan fields, and not everyone along the route is supportive of a pipeline crossing the beautiful Canadian Rockies to the Pacific Coast.

For President Obama, it must have been a tough decision, alienating his supporters in the environmental community or giving his Republican opponents further ammunition as a job killer. Delaying to decide one way or another, however, has made enemies on both sides and merely means that he, or his successor in the White House after the 2012 election, would have to face the very same painful issue.


Footnote: Intertwined: Energy and politics

Everyone knows that energy and politics have always been and will continue to be intertwined. In November 2011, the US State Department acknowledged the fact by creating the Bureau of Energy Resources within its already large bureaucracy to focus exclusively on energy.

In a recent speech announcing the creation of the new office, Secretary of State Hillary Clinton said, “You can’t talk about our economy or foreign policy without talking about energy.” With a six-fold increase in staff, Carlos Padcual will head the new bureau.

Among other things, the office will promote clean energy and support the export of US technology overseas. While it is not clear if having one more energy office in one more government agency is a step forward, it clearly acknowledges how political energy has become.

Why Does The Grid Fail With Such Regularity?

November 18th, 2011

This is a sample article from the November 2011 issue of EEnergy Informer.

Our existing grid is not as reliable as one would expect. What is the cure?

With no warning some 6 million residents across a wide stretch of Southern California, Southwest Arizona and the northern top of Baja California in Mexico lost power on 8 September 2011. It took hours to restore power. Coming a mere 8 years after the much bigger blackout affecting over 50 million people in Northeast US and province of Ontario in Canada in Aug 2003, it reminded anyone who needed reminding that the US electric grid is not as reliable or dependable as one would expect it to be.

The fragility of the grid, of course, is not limited to America. Similar accidents afflict other regions of the world, to varying degrees. Smaller failures, like smaller earthquakes common in California, are simply too frequent to get much publicity.

Why so many failures?

The reality, however, is that the grid fails with regularity, and the failures are commonly blamed on faulty equipment and human error – as in the case of the most recent one, which has been blamed on a maintenance worker at North Gila sub-station near Yuma, Arizona. What ever the reason, a critical 500 kV line was inadvertently knocked off, causing massive chaos in generation-poor San Diego region, which is dependent on power imported from the East and the North.

Within seconds – it quickly gets complicated – a dozen major power plants including 2 big reactors at San Onofre Nuclear Generating Station, operated by Southern California Edison Company, shut down, as designed, to protect their equipment from damage from the cascading failure. With so much generation out so abruptly, and so little back-up generation available to fill the void, the grid crashed, and left millions in the dark for the night. It could have been much worse.

An investigation is underway by the North American Electric Reliability Corporation (NERC) and Federal Energy Regulatory Commission (FERC). One or more reports will be published once the cause of the accident is determined. Recommendations will be issued, some followed, others ignored, until the next accident. We know the routine by now.

Partially in response to these frequent failures of the high voltage grid, which are to be distinguished from far more frequent and even more annoying failures of the low voltage distribution network — which are routinely experienced following every major and many minor storms — many millions of dollars are invested in the cure all, broadly defined as the smart grid. Chief among its many purported benefits are increased reliability, fewer and more manageable failures, and faster service restoration when failures do occur.

It could happen again

Smart grid, of course, will not be the panacea for all the grid’s woes, but any improvement is better than none. The question, as always, boils down to “at what cost and to what end?” Studies of the cost-effectiveness of the smart grid generally conclude that the ultimate gains will exceed the costs. But even if one agrees with the results of such analyses, it remains to be seen who bears the costs and who gains the benefits – since the incidence of the costs and benefits tend to be uneven among the affected stakeholders.

Is investment in smart grid smart?

The answer depends on who you ask, and certainly on who pays for the investments and who reaps the benefits.

A case in point is The Energy Infrastructure Modernization Act, authorizing a multi-year, multi-billion dollar investment to modernize the grid in the state of Illinois. The bill, which was to take effect in 2012 and run through 2021, passed both chambers of Illinois General Assembly in May 2011 but was rejected by Illinois Governor Pat Quinn in September. It would have made it easier for state’s utilities to recoup their investments in smart meters and smart grid initiatives by passing on the costs to customers.

Citing that there were “no guarantees of improved service” in the proposed rollout of smart meters and related grid improvements, Gov. Quinn said, “I will not support a bill that contains sweetheart deals for big utilities, which could leave struggling consumers to pick up the tab for costs such as lobbying fees and executive bonuses.”

Referring to recent service interruptions in Illinois, Gov. Quinn said, “More than 1.5 million people and businesses have had to deal with power outages and service disruptions this summer,” adding, “Now these same utilities are trying to change the rules to guarantee themselves annual rate increases and eliminate accountability.” Ouch.

The state’s biggest utility, Commonwealth Edison Company (ComEd), a unit of Chicago-based Exelon, disputed the governor’s assessment, pointing to a study by consulting firm Black & Veatch that, among other things, claims that ComEd customers could save $2.8 billion on their electric bills over the 20-year life of the meters. As it turns out, the lawmakers were able to override the Governor’s veto, allowing the bill to proceed.

ComEd’s CEO, Anne Pramaggiore, said, “As other states are building more efficient and reliable electric grids, Illinois is in danger of falling behind.” In a press release, ComEd also referred to a July 2011 white paper by the Institute for Electric Efficiency, covered in October issue of this newsletter, which concluded that investments in smart meters and related peripherals are cost-effective.

Winds Of Change Blowing From China, Where Else?

October 25th, 2011

This is a sample article from the October 2011 issue of EEnergy Informer.

Western turbine manufacturers brace for stiff competition

China may not be where cutting edge research takes place or innovative technologies emerge, and Chinese manufacturers are not usually the first to develop and market new products. But, once they identify a product as globally marketable, Chinese manufacturers typically copy and apply reverse engineering techniques and then undercut their Western competitors in their own markets. With substantially lower wages, they can be fierce competitors. This pattern is repeated to one product after another, and in one market after another.

Another article in this issue describes how China has cornered the mass manufacturing of photovoltaic (PV) panels, now flooding global markets at costs that drives their Western rivals out of business. The same appears to be happening in the market for utility-scale wind turbines where China has made impressive progress in the last few years.

What About 5 Years From Now

A mere 5 years ago, there was not a single Chinese wind turbine maker among the top 10 global players. By 2010, there were 4, including #2 Sinovel, closing on the #1 Vestas of Denmark, and already ahead of America’s GE Wind and Germany’s Enercon (see pie chart), according to BTM-Consult, a market research firm. If this growth pattern continues, Chinese can be expected to dominate the manufacturing of wind turbines, reducing their Western rivals to secondary niche players.

China on Top

This would not be a big deal if it were not for the fact that the market for wind is projected to grow at double digit rates over the coming decades in a number of key countries. Chinese manufacturers are thus poised to gain a growing slice of a rapidly growing pie.

For example, European turbine manufacturers, who currently enjoy 89% of the European, 32% of the US and 37% of the global market, according to the European Wind Energy Association (EWEA), may end up losing considerable market share to Chinese, Indian and other low-cost rivals.

Henrik Stiesdal, Siemens Wind Power’s Chief Technology Officer was quoted in an article in the Financial Times (29 Aug 2011) saying, in part, “… you have to take the challenge from China and other low-cost countries seriously,” an understatement given the recent experience with PV manufacturing.

Robust growth attracts new entrants

China’s state-owned banks, who follow official government policies, have deep pockets and can be patient investors while their Western counterparts are accountable to impatient private investors. It is not just low wages.

The same fate awaits GE, currently the dominant player in the US where India’s Suzlon has established a foothold, despite sporadic quality problems.

Chinese are coming

Advanced technology and know-how still matters but Western manufacturers simply cannot compete with the developing world’s low wages, and that is not going to change unless their wages rises to the Western levels — or God forbid — the Western wages drop down to theirs.

Greening Of Japan

September 18th, 2011

This is a sample article from the September 2011 issue of EEnergy Informer.

A proposed law aims to kill two birds with one stone.

With no indigenous energy resources of its own, aside from renewable, Japan’s energy policy has been to rely on nuclear power for a growing share of its domestic needs, supplemented with imported oil, natural gas, and coal. Nuclear energy offered a second attractive attribute: low greenhouse gas (GHG) emissions, especially if someone else does the mining and processing of the nuclear fuel. As one of first signatories of the soon-to-expire Kyoto Protocols, Japan has pledged to reduce its carbon footprint.

The policy was welcomed by Japan’s 10 major privately owned electric utilities, who are vertically integrated and have traditionally enjoyed a near monopoly hold on all aspects of electricity generation and distribution — a situation which has been slowly eroded in recent years with the arrival of independent power producers (IPPs). Continued reliance on nuclear power favored the status quo — who else could afford the massive investments in building new nuclear power plants if not vertically integrated utilities with captive customers — encouraged by supportive government policies?

Over the years, government policy, utility strategy, and the role of regulators in charge of nuclear safety became increasingly intertwined. For example, the regulatory agency in charge of Japanese nuclear safety was also promoting nuclear power with tacit government approval, prodded by Japanese utilities, who wished to maintain their monopoly and vertically integrated status.

Less nukes, more renewables

The big earthquake and tsunami of March 2011 not only knocked out power to the Fukushima nuclear plant, but more important, exposed the cozy relationship that had existed between the regulator and the regulatee, long tolerated by the government. The result was the loss of public confidence in the nuclear industry as well as the standing of the Japanese nuclear safety and regulatory apparatus.

In mid August 2011, with the personal backing of the prime minister Naoto Kan, a landmark law has been introduced at the Japanese Parliament that, if passed, will kill two birds with a single stone. It will give a much needed boost to renewable energy and — more important — it will loosen the tight grip of the dominant utilities.

The law’s two main features are:

  • The introduction of a basic feed-in-tariff (FIT), similar to those in use in Europe, for all qualifying renewable generation fed into the grid. The FIT would be set, and periodically adjusted by the Industry Ministry; and
  • An obligation on utilities to buy what is offered at the set price.

Key features of the Japanese law have a vague resemblance to the Public Utilities Regulatory Policy Act (PURPA) passed by the US Congress in 1978. PURPA specified how much should be paid for power generated by non-utility generators — later known as IPPs — and obligated existing utilities to buy what ever was offered to them by qualifying facilities or QFs. PURPA’s FIT equivalent was called avoided cost.

Despite many shortcomings and uneven implementation in different states, PURPA eventually broke the monopoly hold of US utilities in power generation business and was instrumental in ushering in competitive wholesale markets, now dominant in many parts of the US.

With the passage of the law, Japan, which currently gets only 9% of its generation from renewable resources — mostly hydro, with some geothermal, wind and solar — may increase its reliance to 20% by early 2020s. If successful, it will allow a diminished role for nuclear power, reduce imported energy costs without increasing the country’s GHG emissions. If it further loosens the utility’s monopoly status, that would be the icing on the cake.

Mr. Kan, who is expected to retire soon, said he believes Japan will experience “explosive growth” in renewable generation. History may count it as his most enduring legacy.
