Big green agenda a threat to grid reliability

 American Action News:

The Independent System Operator-New England (ISO-NE) is warning that the batteries pushed by blue states in the region to prepare the grid for increased solar and wind generation may have significant trouble recharging in low temperatures.

The grid operator could end up spending about $1 billion each year on transmission until 2050 to prepare the grid for the green transition being pushed by deep blue states in the region like Massachusetts and Connecticut, according to ISO-NE’s 2050 Transmission Study. Battery systems comprise about 45% of ISO-NE’s in-progress transmission projects, but ISO-NE warned in its Regional Electricity Outlook that the batteries could “struggle to recharge during the winter months.”

At the federal and state levels, elected Democrats are pushing hard to phase out fossil fuel-fired power infrastructure and replace it with sources of green energy like wind and solar. Connecticut, Maine, Massachusetts, New Hampshire, Rhode Island and Vermont — the states that are served by ISO-NE — all have green energy mandates of this nature, albeit with slight variations in timelines, according to the National Conference of State Legislatures.

“Modeling in the Future Grid Reliability Study found that, under some scenarios in a potential 2040 power system, the battery fleet may be depleted quickly and then struggle to recharge during the winter months,” the Regional Electricity Outlook warns. “This is a time of year when batteries may be needed most to fill supply gaps during periods of high demand due to cold weather, as well as periods of low production from wind and solar resources. Daily average charge levels remain higher in spring, when demand for electricity from the grid is lower and the region sees significant production from solar installations.”
...

Wind and solar are at best supplemental sources of energy and they are not in themselves reliable enough tp provide consistent energy to the grid that can supply enough electricity for homes and businesses.

Should Republicans go ahead and add Supreme Court Justices to head off Democrats

Washington Post: Some Democrats eye adding more justices to the Supreme Court to change its ideological bent The once-remote idea has gained the attention of liberals angered by the GOP push to remake the federal courts. Probably the easy way to defeat this court-packing scheme is for Trump to propose doing the same thing now.  It would lead to Democrat denunciations and claims that it would be wrong, thereby blowing up any attempt by them in the unfortunate event of Democrats winning a presidential election.

29 % of companies say they are unlikely to keep insurance after Obamacare

Conn Carroll: A new survey of 368 midsize to large companies found that 29% of them are considering terminating their active employee health care plans when Obamacare is full implemented in 2014. Only 71% of employers surveyed said they did not expect to drop their health coverage, while 20% said they did not know and 9% said they were planning to exit. The latest survey, conducted by Towers Watson, echoes an ealier survey by McKinsey & Co. finding that 30% of private-sector employers were planning to drop their employee health insurance coverage by 2014. When the Congressional Budget Office crunched Obamacare's spending numbers, they estimated that only 7% of employees currently covered by employer-sponsored plans would lose their plans. ... This means the cost of the health care fiasco will be hundreds of billions more than estimated by the CBO and Congressional Democrat. It is also clear that Obama's pledge that you could keep your health care plan if you wanted t
