Latest DOE LED Report
 Illustrates Transition
 In Electric Power Sector

I was at Home Depot this weekend (so many tools, so little time) and they had a special on LED lights that caught my attention—a four pack of dimmable 60-watt replacement LEDs was selling for $9.88, or just under $2.50 a bulb. I’m not the type to track day-to-day pricing for much of anything, but the display caught my attention because I had just finished reading the Energy Department’s latest report on the status of the LED market—which found that the typical dimmable 60W replacement bulb in 2016 cost roughly $8 apiece.

This is important for two reasons. First, DOE assumes that LEDs are steadily going to account for an ever-larger percentage of the installed lighting stock in the United States, estimating that by 2035 86 percent of all the lighting in the country will be LEDs of one type or another and that these vastly more efficient lights will cut primary energy use by 3.7 quadrillion British thermal units (Btus)—that’s a lot of electricity that will no longer be needed, about 10 percent from the 2016 level, in fact, when roughly 37.5 quads were used to generate electricity in the U.S. (Paying attention out there in utility land?) But those DOE forecasts rely heavily on pricing assumptions, and if the current price of the most commonly used LED has already tumbled below $2.50, down roughly 70 percent from just a year ago, that means the nationwide take-up of LEDs almost certainly will be faster than DOE currently estimates.

Second, the sharply declining price of this lowly light bulb is a symbol of the massive changes under way in the energy industry, such as the steep declines in solar and windpower costs, the surge in corporate interest in cleaner energy and the plateauing of electricity demand. These changes are largely market-driven and, thankfully from my perspective, outside the reach of politicians on either side of the aisle.

Storage Puts Utilities
 In A Big Bind
 On Demand Charges

Electric utility executives already fretting about slow/no growth in their service territories have another item to add to their growing list of worries: the prospect that many of their commercial customers could begin installing behind-the-meter storage to lower their demand charges.

A recent white paper from DOE’s National Renewable Energy Laboratory and the Clean Energy Group, a nonprofit advocacy organization, shows that it could be economic for almost 28 percent of commercial customers across the country to install batteries at their business sites to cut their electricity consumption during specific periods of the day, thereby reducing their exposure to utility-imposed demand charges. This would amount to a one-two punch for utilities: electricity sales would drop if the batteries were linked with solar and the amount of revenue collected from these charges would fall, not a pretty picture for the utility industry.

Vanishing Demand,
 Not Trump Coal Crusade
 Is Real Issue For Utilities

It’s planning time in the electric utility industry, and a raft of new reports make two points abundantly clear:

  • Efforts to “save” the coal industry are bound to founder since utilities, as a group coal’s largest customer by far, have moved on and are planning a cleaner future in which the black rock’s current share of the electricity market, in the low 30 percent range, is as high as it’s ever going to get.
  • Vanishingly small increases in demand (and the occasional outlook for declines) will be a major issue for the industry in the next 10 years.

In its latest 10-year power plant siting plan, for example, Florida Power & Light pointed out that it was continuing its efforts “to move away from coal-fired generation.” In total, the utility said it planned to take 1,216 MW of coal-fired generation off its system by the first quarter of 2019. (FPL’s site plan can be found here.)

Similarly, in its recently filed 2017 integrated resource plan (IRP), PacifiCorp, the sprawling utility holding company that serves 1.8 million customers in six western states, said its preferred generation portfolio going forward “reflects a cost-conscious transition to a cleaner energy future.” Through 2028, PacifiCorp said it would be able to meet its system-wide power needs through demand side management (DSM), new renewable (primarily wind) generation and short-term purchases on the wholesale market. Looking longer-term, the company said it planned to shutter 3,650 MW of coal-fired capacity by 2036. (PacfiCorp’s IRP and other backup information can be found here.)

 Green Power Revolution
 Grinds Forward,
 An Unstoppable Glacier

Webster’s defines revolution as “a sudden, radical or complete change.”  The ongoing revolution in the United States electric utility industry fits that definition to a T. The changes have been unbelievably quick (at least by company standards, if not by activists’ desires), and the long-term impacts are going to be both radical and complete. Importantly, particularly in today’s political climate, I would add that the transition is unstoppable—like the inexorable forward advance of a glacier.

What got me thinking about this were two short news releases from the National Electrical Manufacturers Association earlier this week regarding shipments of LEDs during the third quarter of 2016 (the latest data it has available). In one, NEMA said that shipments of A-type LEDs (the most commonly used bulb for residential applications) topped 30 percent of the total for the first time, continuing a surge that has seen its market share climb from essentially zero just two years ago.

In the second, NEMA pointed out that it had added so-called T-LEDs to its statistics tracking shipments of the linear fluorescent tubes (marketed largely as T5, T8 and T12, which denote their diameter in eighths of an inch) that dominate the commercial and big box retail markets.  In the third quarter, NEMA said, T-LEDs accounted from 12.8 percent of all shipments in this category—almost double the 1st quarter results, the first time NEMA even included the segment in its quarterly report. As with the A-line LEDs, sales of T-LEDs were essentially nonexistent in 2014.

New Cheerleader In Chief Can’t Change Coal’s Fall, Rise In Gas, Renewables

The bright shiny package the coal industry unwrapped Christmas morning—the one it hoped was filled with rising and lasting demand for the black rock—is actually little more than a pretty box filled with empty promises delivered by the country’s new cheerleader in chief.

Just 10 years ago, coal was the clear top dog, accounting for just under 50 percent of the electricity generated annually in the U.S. (Coal’s total in 2006 was 48.9 percent, the last year it actually topped the 50 percent level was 2003.) This year, coal is likely to play second fiddle to the surging natural gas sector; the Energy Information Administration’s latest Short Term Energy Outlook (released Dec. 8) estimates that coal will account for 30.4 percent of the nation’s electric generation this year, below the 34.1 percent stake controlled by natural gas. And no amount of industry wishful thinking or presidential conceit is going to change that—the markets have changed.
