Battery Storage Becoming the Norm for Utilities

Even as recently as two years ago, utility-scale lithium-ion batteries were considered cutting edge technology, and just a few forward-thinking utilities were experimenting with the concept. These days, though, it seems there are few utilities that are not building, or at least not considering, the technology.

In some cases, batteries are being linked with solar generation (called solar+battery). In other cases, the batteries are part of microgrids, which can include solar and other sources of generation. Microgrids appeal to utilities for remote-location generation/storage, reducing or even eliminating the need for transmission or distribution wired systems through rough, isolated terrain. And in still other cases, battery projects are being designed and built as a way to store surplus generation from traditional baseload generation (such as coal) and make it available later when customer demand increases.

Last week, for example, Duke Energy announced plans to spend $500 million on battery storage over the next 15 years, increasing its current storage capacity 20-fold. Current projects include a 9-megawatt (MW) battery project in Rock Hill, N.C., and a 4-MW battery project (part of a solar-powered microgrid) in Hot Springs, N.C.

Up north, New York Power Authority (NYPA), which to date has never been involved in battery storage, just announced plans for a 20 MW battery project in the northern part of the state, largely because current transmission constraints in the utility's service territory often prevent energy from being delivered downstate.

"Storing renewable energy, by using a battery to absorb excess generation for later delivery through projects like this one, is a viable solution to this transmission constraint," states the NYPA press release.

NYPA also believes the project will help to kick-start energy storage adoption throughout the state, supporting Gov. Cuomo's Energy Storage Roadmap, a plan designed to achieve massive energy storage targets in the state, including construction of 1,500 MW of energy storage by 2025.

"The North Country Energy Storage Project will be a first-of-its-kind for the Power Authority," said Gil Quiniones, president and CEO of NYPA. "Developing, operating and optimizing a lithium-ion battery system of this size will help us advance energy storage development efforts at the Power Authority, as well as position us to lead storage adoption across the state."

Out west, Hawaiian Electric Cos. (Hawaiian Electric, Maui Electric, and Hawaii Electric Light) just announced seven solar+storage projects on three islands, representing the largest infusion of renewable energy in the state's history. The seven solar projects, totaling 255 MW, will be connected to battery storage systems that will be able to capture up to four hours of electricity for later use.

Omaha's first snowfall of the season causes slick roads, over 50,000 power outages

Kids played board games by flashlight, folks threw extra logs into the fireplace and at least one couple camped out in the driveway in their heated RV.

The wet, heavy snow that blew through eastern Nebraska on Sunday left thousands without power, yet people remained connected as they shared images via Facebook of their return to what some jokingly described as "pioneer days."

For others, especially the elderly and ill, the loss of power created anxiety and worry as people tried to sort out what to eat and how to stay warm overnight.

At the peak of the storm Sunday afternoon, the Omaha Public Power District reported 57,000 outages, according to spokeswoman Jodi Baker. About 10 p.m., that number remained at 27,000, according to the utility's website.

By 7:45 a.m. Monday, the utility was reporting 4,900 without power, most of those in Douglas County. Virtually all — perhaps 99 percent — should have power restored by midnight Monday, Baker said.

OPPD called in nearly 100 personnel to help with repairs. Additionally, the Nebraska Public Power District sent in crews to assist OPPD with power restoration, said Mark Becker, NPPD spokesman.

Eight school buildings in the Westside Community Schools district remained without power on Sunday night, and were at risk of not holding classes on Monday. The district said it would announce by 6 a.m. Monday if any school buildings were canceling classes.

The outage forced some grocery stores to scramble to save what refrigerated and frozen foods they could.

The Hy-Vee at 5150 Center St. had a generator kick in after losing electricity about 1 p.m., but the generator wasn't enough to power all of its freezers and refrigerators, a manager there said Sunday night.

Workers spent the early afternoon moving food to powered backup storage units on trucks, and what didn't fit had to be thrown out, the manager said.

Electricity was restored there about 8 p.m., he said. He expected the store to be restocked Monday.

The storm set daily records for snowfall, said Scott Dergan, meteorologist with the National Weather Service. Omaha officially recorded 1.5 inches of snow, though some areas saw about 3 inches. Lincoln's official total was 3.5 inches. Before Sunday, Lincoln had never recorded snow on Oct. 14, and Omaha had seen only a trace on that date, Dergan said. Weather records date to the late 1800s.

It wasn't either city's earliest snow, he noted. Omaha's earliest snow was Sept. 29, 1985, when three-tenths of an inch fell.


The cold front that accompanied the storm was expected to usher in the season's first killing freeze, with lows forecast to drop into the upper 20s overnight. Delicate plants and flowers will disappear from the landscape, and the freeze may be enough to ease the misery of allergy sufferers.

A much nicer week is in store: Sunshine and highs in the 40s and 50s.

On Sunday, the sight of sagging trees, weighted down by the snow, and the random sounds of cracking of branches brought back memories of the Oct. 24-26, 1997, snowstorm that devastated trees in eastern Nebraska. In that storm, 13 inches of wet, heavy snow fell over two days, littering the ground with fallen trees, broken limbs and downed power poles and wires. At the peak of the 1997 storm, upward of 130,000 homes and businesses and about 300,000 people were without power — many for up to two weeks.

With that storm on their minds, a number of people headed outdoors Sunday to brush snow from their trees.

Omahan Vince Shay was among those. The sunset maple in front of his Dundee/Elmwood Park home still bears the scars from 1997.

"If you don't like interesting weather, you shouldn't live in Nebraska," Shay mused.

A block or two east, neurosurgeon Steve Doran took a chainsaw to a fallen maple branch.

"Not a good combination," he quipped as he cleared the branch from the driveway.

Sunday's storm brought the most outages OPPD has seen since June 2017, when storms bearing powerful straight-line winds and tornadoes caused 76,000 outages.

Other hazards from Sunday's storm included power lines starting fires after contacting trees in several locations, and tree limbs blocking roadways.

Many traffic lights were not working. By early afternoon, there had been enough fender-benders on snow-slickened streets that the Omaha Police Department stopped responding to minor property damage collisions.

The Nebraska State Patrol reported that it assisted more than 100 drivers on the state's roadways Sunday and responded to dozens of crashes.

Sunday's snow also caused cancellation of events and early closings. The "Support the Girls" breast cancer awareness event in Elkhorn was postponed to Saturday. Vala's Pumpkin Patch closed about 2 p.m. due to safety concerns.

"We were having some branches falling, and it was just unsafe to have people on the farm," Jan Vala said. "People were here having fun, but safety comes first."

The Henry Doorly Zoo & Aquarium announced that its "Spooktacular" was canceled. Guests who pre-purchased tickets for the event will be contacted by the zoo's marketing department.

The storm blanketed much of the state. In northwest Nebraska, 5 to 7 inches of snow was reported. The 3 inches that fell in Valentine was enough to set a daily record there, according to the weather service. The previous record had been a trace of snow.

Bitterly cold weather was forecast across much of western Nebraska, and the weather service warned that wind chills could drop below zero in some parts of the state by Monday morning.

Important FAQ about Arc Flash protection Clothing

What you need to know:

What does 8 cal mean when people say, ‘8 cal shirt or garment’?

This term is really an abbreviation of, or slang for, 8 calories/cm², which are the units of measurement of an arc rating. If someone is saying they need an “8 cal” flame resistant (FR) fabric or garment, what they might really be saying they need is an arc rating of at least 8 calories/cm² or greater to meet a personal protective equipment (PPE) Category 2 requirement as defined by standard NFPA 70E. However, the PPE Category 2 level of protection only starts at 8 calories/cm² and goes up to 25 calories/cm², or PPE Category 3. Obviously, the difference in protection at 8 and 24 calories/cm² is significant, so it’s important to conduct your risk assessment prior to specifying a protection level and to understand that PPE Category 2 is a broad statement.

Is it ok to use fabric softener on FR clothing?

The laundering instructions for all FR and arc rated fabrics prohibit use of fabric softeners because most softeners are flammable and will accrete (build up) on the garment over time. The fabric is still FR, but now a flammable contaminant has been added to the surface and can be ignited by a flash fire or arc flash.

Can you use bug repellent with FR clothing?

When applying insect repellents to garments, a waterborne, permethrin-based insect repellent has been shown in testing to not have an adverse effect on flame resistance. However, it is not recommended to use DEET or DEET-containing insect repellents on any FR fabrics. DEET and DEET-containing insect repellents can be flammable, and therefore, have an adverse effect on the flame resistance of FR garments. It is important to note that DEET and DEET-containing insect repellents do not remove or destroy the flame resistance of fabrics, but they mask it. Once the garment is laundered and the DEET and DEET-containing insect repellents are removed, the flame resistance is still intact.

Is it possible to buy one uniform that protects against both arc flash and flash fire?

Yes, there are fabrics that protect against multiple hazards. However, it’s important to remember that not every fabric does. As you’re putting together your FR clothing program, make sure you discuss your hazards with your supplier and you know the FR fabric brand used to make your garments.
