PJM Market: Good, Can Get Better

PJM market is broadly seen as competitive, yet there is room for improvements

This is a sample article from the May 2013 issue of EEnergy Informer.

The PJM market has always been, and continues to be, a source of fascination to anyone interested in organized or competitive wholesale electricity markets:

  • First, it is by far the largest such organized market operating in North America, among the largest anywhere in the world, with 182 GW of installed capacity and a large geographical footprint;
  • Second, PJM was among the first to introduce a number of features, such as locational marginal pricing (LMP), now common place in other markets;
  • Third, PJM has introduced and successfully operates a number of markets, including capacity markets, that are extensively studied by other market operators who believe such a feature may be an improvement to their own; and
  • Its performance is extensively scrutinized by an independent market monitor, Monitoring Analytics LLC, who publishes a massive annual state of the market (SOM) report as well as quarterly updates, available to anyone with plenty of time and patience to sift through.

From sea to middle of the country: PJM’s footprint

As in all competitive markets, prices vary by supply and demand conditions — prolonged and unusual heat waves, for example, create supply scarcity, resulting in price spikes. When supplies are plentiful and demand is modest, the market clears at low prices. Looking at the data for the last decade, showing the components of the prices, 2012 was not a bad year. In fact, overall, energy prices were the lowest they have been in 10 years. There was plenty of capacity and no scarcity to drive up prices.

2012 was not a bad year

What sets PJM apart from certain other markets, such as California or Texas, is the modest penetration of renewables — even including conventional hydro. In Dec 2012, for example, all renewables accounted for roughly 5% of the installed capacity — 8,843 MW in a 181,990 MW network. This may change over time, but as shown in the figure below, PJM’s peak solar generation in August 2012 was barely above 100 MW — that is 0.06% in a system that had 181 GW of capacity in June 2012. Germany, by contrast, routinely experiences periods were solar energy accounts for more than 20% of load.

Where is the sun?

Where PJM excels is in operating a myriad of markets designed to provide opportunities to consumers and their intermediaries to engage in demand response by offering attractive compensation for reducing demand during peak demand periods. These markets have grown over time and are of sizeable significance (graph below).

Demand responds to incentives

What sets PJM aside from other so-called energy-only markets is that PJM runs a multitude of markets for capacity — the details can be found at PJM website or at the SOM report. The prices paid, like market clearing prices for energy, depends on supply and demand conditions for capacity, illustrated in graph bellow.

PJM’s supply curve, shown in the figure on bottom of this post, illustrates supply and demand fundamentals at work. If aggregate demand shifts to the right approaching the system’s installed capacity, prices shoot up as one would expect. When prices rise, however, incentives for demand response motivate more customers to shed load, either directly or through intermediaries. This is just as it should be. When it is cheaper for customers to shed load rather than the market operator to acquire expensive generation from peaking units, PJM favors the former. Customers gain by avoiding expensive peaking capacity.

Paying for capacity

As is customary, the 2012 SOM report comes with a list of findings and recommendations as identified by PJM’s market monitoring unit (MMU), an independent entity that is solely accountable to the Federal Energy Regulatory Commission (FERC). In its latest report, the MMU concludes that the PJM’s state of the market was good — the various markets are deemed to be operating competitively — despite the ongoing presence of structural market power. It offers a number of recommendations including:

  • PJM reduces demand in the capacity market by 2.5%. The MMU recommends that this reduction be eliminated because it suppresses prices.
  • PJM market rules include demand side products in the capacity market that require only 60 hours of response in a year, in contrast the required 8,760 hours of availability required of generating units. The MMU recommends that PJM eliminate the inferior demand side products from the capacity market and retain only an annual product.
  • The MMU recommends that all capacity resources face the same incentives and that those incentives require that units must operate when called to receive capacity payments. The current incentive rules permit payment of 50% of capacity market revenues to generating units that do not perform.

Economics 101

Clearly, even a well-designed and functioning market such as the PJM can do better.

PJM’s SOM report has much more to offer than can be summarized in this space. For anyone interested in capacity markets, it describes the limitations and the downside of such markets. Like everything else in life, capacity markets come with challenges of their own.

Nuclear’s Future May Be Small, As In SMR

A new generation of smallish reactors may give nukes a second lease on life

This is a sample article from the April 2013 issue of EEnergy Informer.

Broadly speaking, commercial nuclear reactors built over the past 6 decades have gradually gotten larger, safer, more sophisticated and more expensive. There are many reasons for this counter-intuitive trend. One would typically expect technological improvements, learning-by-doing coupled with economies of scale of mass production to result in lower per unit costs.

If the same applied to other generation technologies, nuclear would not fare too badly. But the cost of competing technologies has generally fallen, measured in per unit cost of installed capacity. The per unit cost of renewable generation, for example, has fallen dramatically, most noticeably for solar-generated technologies in the past few years.

Making matters worse for nuclear power in the US, currently with the biggest installed nuclear capacity, natural gas prices are presently so low that natural gas-fired plants now compete on operating costs with older, less efficient nuclear generation. As a result, a number of older nuclear reactors in the US are expected to be shut down before their operating licenses expire — an unimaginable scenario until natural gas prices began to fall in the US due to a supply glut.

Not getting cheaper over time?

But even in Europe and Japan, where natural gas prices are significantly higher than in the US, few private investors are building new nuclear plants. The only two advanced reactors currently under construction in Europe, one in France and one in Finland, are both behind schedule and over budget.

In February 2013, TVO, the owner of Olkiluoto 3, the first European generation III nuclear reactor, announced that the unit will probably not commence operation before 2016. The latest delay was blamed on failure to get timely regulatory approval for the reactor’s instrumentation and control equipment. This, coming on top of several prior disappointments have blown out the construction time by several years, and led to billions of Euros in budget over runs.

Against this backdrop, many within the nuclear community believe that the future of commercial atom lies in small, standardized modular reactors — that can be mass produced in a factory and shipped to site for assembly. They are referred to SMRs, for small modular reactors.

The idea is anything but new. The concept has proven feasible since USS Nautilus, the first US nuclear powered submarine, went into service in 1955 with a 10 MW reactor on board. The US navy found nuclear powered submarines reliable, durable, safe, and quiet — a big plus during the cold war years. They did not need to surface for air, could remain submerged for prolonged periods with infrequent need for refueling. And there are no reports of accidents or fatalities for sailors who live within a few feet of the reactors. According to Lloyd’s Register in London, over 600 nuclear reactors have been in operation since then with an estimated 200 in the maritime environment.

Nuclear club

How small must an SMR be? There is no firm definition, but anything as small as 10 to 35 MW to 300 MW or larger qualifies. The International Atomic Energy Agency, (IAEA), based in Vienna, Austria, puts the upper limit at 700 MW — something that would probably be too large to manufacture and ship to site. Using this definition, IAEA says there are currently125 SMRs in operation world-wide with 17 under construction in 28 countries.

A number of manufacturers are prospecting in what many believe could be a commercially viable niche, especially for developing countries that would benefit from the assembly of prefabricated modules on site. A handful of companies including Westinghouse, Babcock & Wilcox’s (B&W) Holtec, NuScale Power and others are pursuing prototypes expected to become operational in mid 2020s.

Among the most advanced is the B&W’s mPower SMR, a 180 MW advanced pressurized water reactor (PWR). Just how advanced is it? In February 2013, the Tennessee Valley Authority (TVA) signed a contract to support Nuclear Regulatory Commission (NRC) review of a construction permit application for an mPower SMR at its Clinch River Site in Oak Ridge, TN. TVA expects to submit a construction permit to the NRC in 2015, with a unit in operation as early as 2022. This represents a significant milestone for SMRs — and perhaps a second lease on life for commercial nuclear energy.

Westinghouse, which is owned by Toshiba, is working with a consortium of utilities, including Ameren Missouri and few others, on a 225 MW pressurized water reactor.

Others are pursuing similar dreams. According to an article in The Financial Times (15 Feb 2013), Russia is building the first of what might be a flotilla of floating nuclear power plants, each with a 35 MW reactor, that can anchor offshore and supply enough power for a community of 20,000. Just plug and go and hope no hurricanes or tsunamis come your way.

China’s Coal Appetite Roughly Equal To The Rest Of The World

Not good news for anyone concerned about climate change

This is a sample article from the March 2013 issue of EEnergy Informer.

Citizens of China’s big cities don’t have to look far for evidence of how much coal is consumed in China and its devastating effect on the environment. All they have to do is to look out the window — which in many days may barely allow them to see across the street. For anyone not familiar with China’s coal appetite, the graph on right speaks volumes. It shows the China’s coal consumption, doubling since 2000, is approaching the combined global consumption outside China.

Moreover, while global coal consumption outside China has been flat since the 2008 financial crisis, China’s growth shows no apparent signs of a slowdown (graph below). Currently, China accounts for 47% of global coal use — a figure that might reach the 50% mark in 2013.

Rise of China, and coal

Driven by growing demand in China, India and other developing countries, global coal consumption is projected to continue. According to December 2012 projections by the International Energy Agency (IEA), coal could surpass oil as the world’s top source of energy by 2017. IEA says that coal use will grow virtually everywhere except in the US — where plentiful and cheap natural gas is unseating coal as the primary fuel for power generation.

US, currently the second biggest global coal consumer, is likely to move down the rankings, replaced by India. America’s greenhouse gas (GHG) emissions are likely to decline as a result of these shifts, while India’s will increase. No surprise there. More coal means higher GHG emissions.

Rise of China’s coal addiction

Against this backdrop, there are major shifts in global coal production and trade. US coal miners, faced with declining domestic sales, are increasingly looking at export markets, with Europe as the main destination where coal currently competes favorably against pricy gas (graph below). Once Europe further tightens its GHG emissions, markets in Asia will fill the void, until they discover what everyone already knows — namely the fact that coal is carbon heavy.

Looking to export markets

Meanwhile, China has overtaken Japan as the largest importer of coal while Indonesia is expected to pass Australia as the world’s largest exporter of coal by 2017. These shifts, while happening slowly, are significant on multiple levels, for both major coal exporting and importing countries.

Can China’s insatiable demand for coal be slowed or reversed any time soon? IEA examined a scenario where China’s annual economic growth rate was assumed to slow down to 4.6% — low by Chinese but high by OECD standards — yet the country’s coal consumption would continue to grow even under such a draconian assumption.

For Growth Look Outside OECD

Bifurcated future shows mature markets, and the rest of the world, diverging

This is a sample article from the February 2013 issue of EEnergy Informer.

ExxonMobil’s annual energy outlook, released in late December 2012, provides an educated view of the global energy supply and demand to 2040, albeit from the perspective of the world’s biggest listed oil major. Even though Bill Colton, Exxon’s VP for Corporate Strategic Planning claims that the report’s projections are not necessarily what Exxon would like to see, it would be foolish to assume that the oil giant is indifferent to what happens or, for that matter, can refrain from attempting to influence the outcome to its advantage. After all, there is a lot at stake for a company like Exxon who has invested billions in fueling the world’s voracious appetite for liquid fuels and gas.

Mostly in Asia & Africa

The fundamental drivers for energy demand are well-known, growing population — overwhelmingly in developing economies — growing income levels and growing aspirations of millions of people who will join the ranks of the lower and middle class between now and 2040 for higher living standards. A glimpse at global population projections (graph above) speaks volumes on what will drive global demand for energy; clearly it is not from the developed parts of the world.

For oil majors like Exxon, Shell, BP, Total, as well as energy exporting countries like OPEC, Australia, Brazil and South Africa — to name a few — future growth markets are clearly outside OECD. The OECD demand, while substantial, is not projected to grow; contrast graph below on left for the former and on right for the latter.

Non-OECD energy demand, which is now roughly equal to OECD demand, will more than double by 2040 while OECD demand remains flat, or possibly drops modestly, depending on assumptions about economic growth rates, improvements in energy efficiency and, of course, energy prices. The same applies to developing countries, of course, but it is hard to imagine flat demand outside OECD no matter what assumptions are made. Population growth outside OECD, for example, is virtually guaranteed to continue to rise for several decades before it will plateau.

For growth, look beyond OECD

But a closer look shows other important developments. Combined energy demand in China and India — Chindia — for example, is projected to plateau somewhere in mid 2030s and shows a modest decline afterwards as these two countries reach the peak of their industrialization and urbanization (bottom two segments of graph above on left).

Middle East, historically seen as mere oil exporters to OECD, will evolve into major energy consumers. A number of current exporters will turn into net importers. By 2040, the average Middle Eastern citizen will use as much energy in the residential sector as in North America, slightly more than the average European — the latter two are projected to use slightly less on a per capita basis mostly due to continued improvements in energy efficiency (graph below).

Middle East: Catching up with the Americans

Oil majors have little to worry about, assuming they can find, process, refine, transport and retail liquid petroleum products for as long as the eye can see. While demand in traditional markets as in North America and Europe appear saturated and bound to shrink over time, the rest of the world shows no sign of reaching demand satiation, certainly not within the 2040 time period (graphs below).

Blame it on transport

The same patterns are apparent in electricity generation sector, where little to modest growth is projected in developed economies while non-OECD demand shows no bounds (graph below). But even here, electricity demand in China is projected to plateau in 2030s.

Electrifying

For those concerned about climate change, Exxon’s crystal ball suggests that one might expect a peak in energy-related CO2 emissions sometime in 2030s (graphs below). It shows OECD emissions on the decline, followed by the rest of the world. Clearly, the results will critically depend on assumptions about policy changes — say aggressive renewable targets — relative prices — say cost of renewable vs. conventional generation or adoption of carbon taxes — and other factors such as an international binding treaty to reduce greenhouse gas emissions.

Trust me, we’ll eventually reach a plateau

By now, it should come as no surprise to anyone that Exxon has joined the International Energy Agency and the US Energy Information Administration to predict that North America will become a net energy exporter by 2025 — the date varies somewhat depending on who is doing the analysis and the assumptions (graph below).

Looking rather rosy for North America

Unconventional natural gas production is among the reasons as is more efficient utilization of energy. Coal consumption, while remaining robust, will drop in relative terms assuming more natural gas at lower prices. Mature economies are projected to produce 80% more GDP while using the same amount of energy. Everyone has heard these before.

As observed in prior reviews of similar long-term projections of energy supply and demand produced by the likes of Exxon, these studies tend to take a hands-off, back-seat approach even though it is hard to imagine that the companies are indifferent to the outcome or mere bystanders in how the future unfolds.

What is lacking is a sense of purpose, or grand design — if there indeed is one — beyond finding and selling more oil and gas. While no motorist looks forward to a gas station with empty tanks, or with prices that are out of reach, shouldn’t a company with the size, resources, and clout of Exxon do more than merely trying to keep the gas pump from drying up?
