In San Antonio Texas, home of the Alamo you'd usually expect the nuclear option to be popular. To UK eyes, San Antonio also raises eyebrows in that the local utility is (municipal) government owned, a quite common US phenomenon.
The owners of CPS Energy, who just happen to be the voters via a board of trustees, seem to work pretty well:
Thanks to a diversified mix of fuels including coal, natural gas, nuclear and renewable energy, monthly residential bills for CPS Energy customers are the lowest in the country when compared to the bills of residents living in the 20 largest U.S. cities.
Lately, CPS has been studying a new nuclear plant and just returned from a shopping trip to Tokyo where they encountered sticker shock
The nuclear option isn't dead yet — the utility's trustees will learn Monday whether last week's trip to Japan yielded an estimate low enough to win back City Council support. But its prospects have dimmed since news that a $4 billion cost estimate increase had been kept under wraps, leaking out just two days before a crucial council vote on financing.
And while Mayor Julián Castro says he is committed to protecting the utility's investment thus far, depending on what he hears at Monday's utility board meeting, he's ready to walk away from the deal and begin looking at alternatives.
Unlike in the UK, when the government wants to do something, they can consider all the options, but critically make a decision as well:
For CPS Energy, which spent the summer touting the nuclear expansion as the most affordable choice, natural gas is the next best option.
At dozens of public meetings across the city, CPS Energy officials had said nuclear energy would cost 8.5 cents per kilo-watt hour, with natural gas coming in at 10.5 cents. The utility estimates wind would cost 12.5 cents, solar 21 cents.
While renewable energy advocates dispute the figures for wind and solar, CPS Energy says they're high in part because they require backup sources of power. But natural gas, unlike wind and solar energy, can generate power 24/7 if needed.
Yet CPS Energy also points out natural gas' weaknesses: its cost has been historically volatile — from highs above $12 per unit to current lows of $3 to $4 — and there are long-held concerns that the supply is declining.
But:
Consensus is growing within the energy industry, however, that new technological advances may have turned conventional wisdom on its head.
The sound of conventional wisdom turning.
