SNIP:
A glut of gas from U.S. shale fields is fueling a power-plant construction boom in several Northeastern states, despite fierce competition that has caused wholesale electricity prices to plummet.

The key for electricity producers is location. Having access to transmission lines to move megawatts to market is vital; but in addition by building close to natural-gas reserves, power producers can more easily access cheap fuel supplies.

In Pennsylvania and Ohio, which sit above the prolific Marcellus Shale formation, companies including Invenergy LLC and Calpine Corp. CPN 0.07%  are building gas-fired power plants capable of generating a combined 8.6 gigawatts when they come online between now and 2020, according to federal data. That output, which is enough to power up to 8.6 million homes, would require about 1.5 billion cubic feet of gas a day—roughly the equivalent of the daily flow through a major pipeline.

The build-out comes as American shale drillers continue pumping so much gas that the price of the fuel has plunged from highs of over $13 per million British thermal units in 2008 to less than $3 per million BTUs today. “The economics are compelling for gas-fired power,” said Andrew Slaughter, head of the Deloitte Center for Energy Solutions.

The power is bound for PJM Interconnection LLC, a power grid that serves some or all of 13 states, including Illinois, Michigan and New Jersey as well as Ohio and Pennsylvania. Competition among wholesale power producers in the market served by PJM—which stands for Pennsylvania, Jersey, Maryland—has become so fierce that a megawatt hour traded for $29.23 last year, the lowest level since 1999, as far back as the grid’s independent market monitor tracks prices.

Though electricity demand remains stagnant overall, the closing of aging coal plants across the U.S. has left some regions in need of new generating capacity. The PJM grid sits at the top of the list. Nearly 9.3 gigawatts of coal-fired electric generation have been retired in the past three years on the grid, while 8.7 gigawatts of gas-fired capacity have been added in that period. An additional 12.5 gigawatts of gas-fired generation is currently under construction and expected online through 2020.

Dynegy Inc. Chief Executive Robert Flexon  said the company has added more than 800 megawatts of new gas-fired generation to its portfolio over the past several years by upgrading facilities that feed PJM and the New England market. He called the new resources “the cheapest megawatts you can find,” saying his company recently has been able to purchase gas for under $1 per million BTUs on numerous occasions.

Older coal and nuclear power plants have been the biggest losers in the competition among power producers, including increased supply from wind. Roughly three-fourths of the electric-generating capacity retired on the PJM grid since 2015 came from coal-fired units, according to federal data.

Some older natural gas plants are also feeling the squeeze from newer combined-cycle gas plants, which use a gas and a steam turbine together to produce more electricity. In PJM, a sixth of the capacity retired since 2015 came from natural gas, according to federal data.

I wonder if that 12% hydro / pumped storage is a normal number, or if they cranked it up because demand was high (cold temperatures) and/or to keep the stored water from freezing up and becoming unusable or a combination thereof....

This weekend, employees took Johnsonville Fossil Plant offline for the last time. Since 1951, the plant generated more than 385 million megawatts of electricity. We are grateful to the employees, past and present, who worked tirelessly to serve the Valley’s energy needs for 66 years.

Most of the hydro is from dams. 
Yes the hydro output is cranked up because of the demands
The pumped storage is still pumped at night when there is low power demands and then used during high demands, during the mourning primarily

Why coal plants don't close sooner - stranded costs....


https://www.seattletimes.com/business/new-mexico-utility-grapples-with-costs-of-closing-coal-plant/

ALBUQUERQUE, N.M. (AP) — New Mexico’s largest electric provider plans to get out of the coal business sooner rather than later and is proposing legislation that could ease the sting of closing a coal-fired power plant that has served customers around the Southwest for decades.

Public Service Co. of New Mexico wants legislative approval for a mechanism that would address how the utility recovers hundreds of millions of dollars in stranded costs that will result from closing the San Juan Generating Station earlier than planned.

The utility closed two units at the plant in December as part of an agreement to curb haze-causing pollution in the Four Corners region. It plans to close the remaining units in 2022, citing market conditions as a wave of utilities across the country look to divest their coal resources.

The New Mexico utility expected to recover as much as $560 million over the course of two decades through traditional financing, but an early closure changes the equation. By financing undepreciated capital through the highest rated bonds possible, utility officials say shareholders could still collect nearly 60 percent of that while saving customers $160 million.

 During Record Cold
While New England’s power grid operator predicted they would have enough energy supplies to meet demand this winter, they admitted there could be problems if record-low temperatures set in.
“While New England has adequate capacity resources to meet projected demand, a continuing concern involves the availability of fuel for those power plants to generate electricity when needed,” grid operator ISO New England reported in November.

“During extremely cold weather, natural gas pipeline constraints limit the availability of fuel for natural-gas-fired power plants,” the grid operator noted.
That’s exactly what is happening right now.

Unrelenting cold since late December has caused energy demand to spike, pushing up prices and straining supplies. New England power companies are struggling to keep up with demand.
New England’s current energy woes are the result of years of state and federal policies aimed at closing coal and oil-fired power plants, largely as part of the region’s effort to fight global warming.

In 2000, New England got about 18 percent of its electricity from coal plants. Now, the region gets around 3 percent — though it’s jumped to 6 percent in the recent cold snap.
The Brayton Point Power Station, New England’s largest coal plant, shut down over the summer. Plant operators decided to close the plant in 2013 after putting in expensive cooling towers to cut pollution.
Most of the shuttered capacity has been replaced by natural gas, but pipeline capacity has not kept up with demands from power plants.
When temperatures drop, natural gas demand spikes as residents clamor to stay warm. But, like in 2014, New England’s pipeline capacity hasn’t expanded enough to fully meet demand during such cold snaps.
Environmentalists have contributed to the problem by protesting large pipeline projects power operators wanted to increase gas deliveries. Things got more complicated when the Massachusetts Supreme Court ruled companies could not enter into long-term gas contracts and pass those costs onto consumers.
The court ruling killed the planned $3 billion Access Northeast pipeline project. The project would have expanded an existing New England pipeline and was expected to save customers $1 billion a year.
 
A second $3 billion pipeline plan, the Northeast Energy Direct project, was mothballed in 2016 amid stiff political resistance.
Gas supply constraints have made New England the world’s most expensive power market. Some power plants have taken to burning oil to generate power, but supplies are running low. Federal air quality regulations are also keeping power plants from burning more fuel.

“The region’s natural gas delivery infrastructure has expanded only incrementally, while reliance on natural gas as the predominant fuel for both power generation and heating continues to grow,” the ISO reported in its winter outlook, which was released at the end of November.

Wonder if they will rethink closing some of the others?

Major Blow: Top German Economist Shows ‘Energiewende’ Can Never Work!
« Reply #67 on: January 05, 2018, 06:18:57 PM »


Germany’s once highly promoted “Energiewende” (transition to green energies) and the country’s feed-in act have been given a grade of “F” by one of the country’s top economists, Prof. Dr. Dr. h.c. mult. Hans-Werner Sinn.
Just days ago the renowned economics professor gave a presentation dubbed “How much volatile power can the power grid take?” before a packed audience in Munich:

Flamanville EPR completes key pre-operational tests
« Reply #69 on: January 09, 2018, 07:16:42 PM »
EDF has completed cold functional tests at the EPR reactor under construction at its Flamanville site in northern France. Flamanville unit 3 is scheduled to begin operating by the end of this year.

Cold functional tests are carried out to confirm whether components and systems important to safety are properly installed and ready to operate in a cold condition. The main purpose of these tests is to verify the leak-tightness of the primary circuit.
The cold functional test phase for Flamanville 3 began on 18 December and was completed on 6 January.
"This stage is part of the system performance testing, which started in the first quarter of 2017, to check and test operation of all the EPR systems," EDF said.
These tests included a leak performance test on the reactor coolant system at a pressure greater than 240 bar - significantly exceeding the normal operating pressure. During this test, more than 500 welds were inspected, supervised by the French nuclear regulator, Autorité de Sûreté Nucléaire (ASN).
EDF is now preparing to conduct hot functional tests, which will start in July. These will involve checking the equipment under similar temperature and pressure conditions to those under which it will operate.
Construction work began in December 2007 on the 1650 MWe unit at the Flamanville site in Normandy - where two reactors have been operating since 1986 and 1987. The dome of the reactor building was put in place in July 2013 and the reactor vessel was installed in January 2014. The reactor was originally expected to start commercial operation in 2013, but owing to delays this is now expected late this year.
EDF has confirmed its roadmap for the Flamanville 3 project drawn up in September 2015, with fuel loading and start-up of the reactor at the end of the fourth quarter of 2018. It also confirmed the project cost is set at €10.5 billion (at the 2015 rate, excluding interim interest).
The first-of-a-kind EPR at Finland's Olkiluoto plant has been under construction since 2005 and has seen several revisions to its start-up date. In October, the schedule for OL3 commencing regular electricity production was again revised from the end of 2018 to May 2019. The unit began functional hot tests last month.
   
The Taishan 1 EPR in China, which has been under construction since 2009, has completed functional hot tests and will be the first EPR to operate. It is expected to start up later this year, while Taishan 2 is scheduled to begin operating next year.

Truman said: “The fundamental basis of this nation’s laws was given to Moses on the Mount.  The fundamental basis of our Bill of Rights comes from the teachings…  If we don't have the proper fundamental moral background, we will finally wind up with a totalitarian government which does not believe in rights for anybody except the state.”
