TVA plots new future with stagnant or declining demand for power

Quote:
TVA's total power load last year was down by more than 10 percent from a decade ago and the federal utility projects demand for electricity will be essentially flat or down even more over the next decade. TVA, which long banked on annual electricity growth of as much as 7 percent, now predicts power demand in 2027 will be nearly 13 percent below the peak level reached 20 years earlier in 2007.

Is Trump's proposal to dump TVA really such a loony idea?

Quote:
Although TVA operates without taxpayer infusions, it also doesn't pay taxes, and its payments in lieu of taxes total far less than a private utility would pay to support local government. TVA has tended to be lackadaisical about debt. As a government entity, it can borrow more cheaply than private enterprise, and its debt has, at times, approached its $30 billion ceiling, though it's now on a downward trajectory.

TVA boosting power output at Browns Ferry with $475 million upgrade

Quote:
Following a record-long 653-day run of power generation at the Browns Ferry Nuclear Power Plant, TVA idled the Unit 3 reactor at Browns Ferry over the holiday weekend and started Saturday to install equipment to add another 155 megawatts of generating power from the boiling water reactor. Similar upgrades are planned on the two other units at Browns Ferry as part of a $475 million program to boost overall power by 465 megawatts by the spring of 2019.

The extra power from the Extended Power Uprate, or EPU, is projected to produce enough additional electricity to power 280,000 more homes and will help TVA boost the share of power it gets from its nuclear power plants to 40 percent.

The power upgrade is far less costly than building new nuclear generation. TVA spent $4.7 billion to add a 1,200 megawatt Unit 2 reactor at Watts Bar in 2016 — or more than $3.9 million per installed megawatt — compared with only $1.02 million per megawatt for the upgraded Browns Ferry units. At Plant Vogtle in Georgia, the new AP1000 reactors are projected to cost more than $6.4 million per megawatt.


It's humbling when you realize that you could build an entire reactor whose output would be less than the uprating of these older reactors.

This is way back in the annals of TVA history, but S. David Freeman is like a smelly old turd that keeps sticking to your shoe:

'Green cowboy' who advised presidents worries the left is lost

Quote:
Freeman, whose first name is Simon but who goes by Dave, is used to being a lightning rod in the energy community. He quashed the development of new nuclear reactors when he helmed the Tennessee Valley Authority in the 1970s and was accused by Republicans of gouging ratepayers during the energy crisis of 2001.

But these days, Freeman is more focused on his nine grandchildren as he makes the rounds on Capitol Hill to push for legislation to pivot the United States to only renewable energy by 2050.


Freeman is clearly hoping to wreck the world's economy before he dies.

TVA doubles net income as colder weather boosts power sales during winter

Quote:
Frigid winter temperatures helped to more than double the cold cash earned by the Tennessee Valley Authority in the first three months of 2018 even though the price of power was cheaper than a year ago. TVA said its sales of electricity in the first quarter of calendar 2018 were up 9 percent over a year ago due to a colder-than-normal weather, which pushed up power usage in the majority of homes and businesses that heat their houses and buildings with electricity in TVA's 7-state region. With more plentiful rains boosting hydroelectric generation and cheaper supplies of natural gas, TVA's price of power still fell by a tenth of a penny from 6.9 cents per kilowatthour a year ago to 6.8 cents per kilowatthour this year. TVA President Bill Johnson said the completion of new natural gas plants and another nuclear reactor in the past couple of years, combined with more than $600 million of annual expense cuts and extra rainfall from Mother Nature, have positioned TVA to both boost earnings and cut its monthly fuel cost adjustment. TVA said Friday its net income in the first three months of the year totaled $462 million on sales of $2.75 billion. At the current pace of earnings, TVA could top the record high $1.2 billion earned in fiscal 2016.

Power demand may slow, requiring more flexibility for TVA

Quote:
The Tennessee Valley Authority needs to have more flexibility as America's biggest government utility adapts to a changing power market with a less certain future, according to the architects of a new 20-year strategic plan. Unlike previous long-term power plans which differed only in how much electricity demand would rise, TVA's new integrated resource plan taking shape by power planners foresees a possible decline in power use in the Tennessee Valley. Although the demand for TVA-generated power once grew by more than 7 percent a year, electricity demand in the Valley appears to have peaked nearly a decade ago and TVA President Bill Johnson said he expects only flat to declining demand in the future. But electric-powered vehicles and more economic growth could still push up future power demand, especially during summertime and winter peaks. Hunter Hydas, project manger for the Integrated Resource Plan, said the key to success for TVA in the future will be flexibility in its power portfolio and response capabilities as more consumers generate their own electricity from rooftop solar and wind turbines while still relying upon TVA for power when the wind doesn't blow or the sun doesn't shun. "In the last integrated resource plan (released in 2015), all scenarios had increasing energy utilization across the 20-year planning horizon," Hydas said Monday during a public, online update of TVA's long-range plan. "For the 2019 plan, we have designed a much wider band of potential futures for energy escalation or de-escalation." TVA, which has shut down more than half of the 59 coal-fired generation units it once operated, is looking at closing the last remaining unit at the Paradise Fossil Plant in Kentucky and the single-unit Bull Run Fossil plant near Oak Ridge. Within the next 20 years, other aging TVA coal plants at Kingston, Shawnee and Gallatin could enter the end of their useful lives and the extended license for the reactors at the Browns Ferry Nuclear Plant will expire and TVA must decide whether to ask for another extension of its oldest nuclear plant or shut down the reactors. Within the next five to 10 years, other long-term power purchase agreement with other energy producers also will end and will have to be either extended, renegotiated or terminated. TVA is trying to develop its 20-year plan for the future — along with the required Environmental Impact Statement for its future plans — for public release in February. Following pubic hearings and comments, TVA directors will vote on the long-range power plan next August when it takes up the 2020 fiscal budget. The goals of the new long-range plan include low cost energy, limited risk, environmental responsibility, delivering reliable power and diversity of power supply. As in the 2015 long-range plan, TVA is collaborating with its IRP Working Group and the Regional Energy Resource Council (RERC) to help develop and shape the new power plan.

TVA, environmental groups duel over the future of solar energy

Quote:
Just about 13 percent of that power now comes from renewable sources, and only 3 percent from wind and solar, according to TVA’s figures. The latter figure is expected to grow over the next decade. But not by much, compared to other power sources. “Solar only operates when the sun shines and wind only works when the wind blows,” TVA spokesman Scott Brooks said via email. “Even hydroelectric power is dependent on the availability of water, which can be more limited in drought conditions.” That requires TVA to have other sources, such as nuclear, natural gas and coal to provide steady power around the clock, he said. Environmental groups say TVA could be doing much more — and that comparable utilities are.


Pro-solar anti-nukes know that they have public opinion on their side. But not physics or engineering. Hence the problem.
