Conflicting Government Rules Are Damaging the Power Grid

One of the strengths of the electric system is its diversity, with energy flowing from generators that use a variety of fuels. But conflicting government policies and poorly constructed markets are reducing that diversity, and the result will be electricity that is more expensive, more prone to price spikes, and less reliable, according to a new study.

The problem may not be immediately evident to consumers, for whom the light switch on the wall is like a water faucet connected to a vast system of reservoirs and feeder streams. As long as the water comes out, the user doesn’t really care where each drop came from. The consumer is well served by the diversity of supply, even if the diversity isn’t obvious.

The same is true for electric current.

But the power grid is changing, according to a report issued Tuesday by the economic analysis firm IHS Markit, Ensuring Resilient and Efficient Electricity Generation: The Value of the Current Diverse U.S. Power Supply Portfolio, which lays out…

A Billion Miles Under Nuclear Energy (Updated)

And the winner is…Cassini-Huygens, in triple overtime.

The spaceship conceived in 1982 and launched fifteen years later, will crash into Saturn on September 15, after a mission of 19 years and 355 days, powered by the audacity and technical prowess of scientists and engineers from 17 different countries, and 72 pounds of plutonium.

The mission was so successful that it was extended three times; it was intended to last only until 2008.

Since April, the ship has been continuing to orbit Saturn, swinging through the 1,500-mile gap between the planet and its rings, an area not previously explored. This is a good maneuver for a spaceship nearing the end of its mission, since colliding with a rock could end things early.

Cassini will dive a little deeper and plunge toward Saturn’s surface, where it will transmit data until it burns up in the planet’s atmosphere. The radio signal will arrive here early Friday morning, Eastern time. A NASA video explains.

In the years since Cassini has launc…

Sneak Peek

There's an invisible force powering and propelling our way of life.
It's all around us. You can't feel it. Smell it. Or taste it.
But it's there all the same. And if you look close enough, you can see all the amazing and wondrous things it does.
It not only powers our cities and towns.
And all the high-tech things we love.
It gives us the power to invent.
To explore.
To discover.
To create advanced technologies.
This invisible force creates jobs out of thin air.
It adds billions to our economy.
It's on even when we're not.
And stays on no matter what Mother Nature throws at it.
This invisible force takes us to the outer reaches of outer space.
And to the very depths of our oceans.
It brings us together. And it makes us better.
And most importantly, it has the power to do all this in our lifetime while barely leaving a trace.
Some people might say it's kind of unbelievable.
They wonder, what is this new power that does all these extraordinary things?

Hurricane Harvey Couldn't Stop the South Texas Project

As Hurricane Harvey battered southeast Texas over the past week, the devastation and loss of life in its wake have kept our attention and been a cause of grief.

Through the tragedy, many stories of heroics and sacrifice have emerged. Among those who have sacrificed are nearly 250 workers who have been hunkered down at the South Texas Project (STP) nuclear plant in Matagorda County, Texas.

STP’s priorities were always the safety of their employees and the communities they serve. We are proud that STP continued to operate at full power throughout the storm. It is a true testament to the reliability and resiliency of not only the operators but of our industry.

The world is starting to notice what a feat it is to have maintained operations through the catastrophic event. Forbes’ Rod Adams did an excellent job describing the contribution of these men and women:

“STP storm crew members deserve to be proud of the work that they are doing. Their families should take comfort in the fact that…

Why the Electricity Market Needs Reprogramming

The Energy Department’s study of the power grid is 187 pages long but it can be summarized in five words: the energy markets are failing us.

"Society places value on attributes of electricity provision beyond those compensated by the current design of the wholesale market," the study found.

Economists like to say that markets "optimize" production and consumption; that is, they set prices in a way that induces suppliers to bring forth the right amount of whatever is being traded, and lets consumers make wise decisions about how much to use, all in a way that improves everybody’s welfare. That’s true, as far as it goes.


But markets are a little like computer programs; they only do what they’re told to. The best they can do is to optimize the factor they’ve been told to use, in this case, price. The market is a tyrant with a hyper-focused goal. The electricity markets are set up almost entirely to optimize price.
But if the economy needs anything else, some policy …

How Does a Solar Eclipse Impact the Electric Grid?

Millions of Americans traveled long distances in hopes of getting a front-row seat for the dance of the heavens today, watching the moon eclipse the sun, from Portland, Oregon, to Charleston, South Carolina. Hundreds more had spent months preparing for an odd complication of the event: the very sudden loss of up to 9,000 megawatts as solar panels were cast into shadow, and then its very quick return. The lost production is the equivalent of about fifteen good-sized coal plants.

How do you keep the lights on when the sun suddenly goes out? The loss and rebound of generation is much larger than the system usually faces, but experts made some serious advance preparation, and were hopeful  largely because of the diversity of generators. Nuclear plants continue to provide the backbone of the system, and generators running on natural gas were called on to power up quickly, and as the sun reappeared, power down even faster.

Such diversity is important because the system has to function throu…

Packing for Mars? Don’t forget the nuclear reactor.

Did you see the movie The Martian? The hero, Mark Watney, an astronaut given up for dead by NASA, uses a radioisotope thermoelectric generator (RTG), a sort-of "space battery," to keep warm during his trek across Mars.
The movie is science fiction but these devices are real- NASA has been using RTGs to power satellites for nearly forty years, and they've been used on major trips to the moon and other planets. But NASA recently announced plans to use nuclear power in a different way- one that hasn't been fully attempted in fifty years. 
The RTGs like Mark Watney’s harness the heat from passive radioactive decay and produce a few hundred watts of electricity, which on Earth would be enough to run a handful of household appliances. But a mission to Mars would require far more power. Now, NASA is working on a reactor that splits atoms, as reactors on Earth do, to make 100 times more electricity than an RTG. The initial plan calls for 40 kilowatts, which on Earth would meet…
