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.
