Markets Must Better Value Flexible, Dispatchable Coal Power

How valuable is a kilowatt hour of electricity? That, of course, depends greatly on when that electricity is produced and just how much it’s needed. Consider the gulf in value of excess electricity generated by solar power midday and the electricity produced by a coal plant when demand is spiking and intermittent sources of power […]

A Failure to Connect the Dots

The U.S. has a growing energy infrastructure problem. More precisely, major transmission lines needed to move wind and solar power from regions of production to centers of demand aren’t being built at nearly the pace needed. Natural gas pipeline additions are also failing to keep up with gas demand. One infrastructure project after another is […]

From Texas to Germany, Grid Reliability Concerns are Growing

Texas’ recent near-miss with blackouts has turned more than a few heads. The challenges posed to the Texas grid, and other regional grids, by growing reliance on intermittent sources of power and, in some cases, an overstretched natural gas transmission system, have caught the attention of regulators and policymakers. Last week, U.S. Senator Kevin Cramer […]

The Texas Reliability Two Step

The Texas grid has been pushed to its limits this week. Demand for power has exceeded supply, prices have soared and energy experts and consumers alike have waited with bated breath for rolling brownouts or blackouts.   On Monday, electricity demand hit a new record and electricity prices spiked to $6,500 per megawatt hour. On […]

When Down is Up

The reduction in the price of electricity from solar and wind power over the last decade has made for a fantastic story. But it’s hiding a more complex and troubling truth. While the price of generating power from renewables has fallen, the cost, or burden, of integrating these intermittent sources of power onto the grid […]

No Way in Hell

The North American Electric Reliability Corporation (NERC) analyzes the reliability of our electricity supply. NERC’s reports and statements are consistently measured, typically packing all the flair and excitement of a buttoned-down white dress shirt. So, it’s with good reason that eyebrows were raised when NERC’s CEO, Jim Robb, recently told the Federal Energy Regulatory Commission […]

Trillions with a “T”

According to new analysis from Wood Mackenzie, transitioning to an all renewables grid in the U.S. by 2030 would cost roughly $4.5 trillion. Remarkably, that cost – estimated at about $35,000 per household – does not account for the costs of prematurely closing hundreds of existing power plants, the inevitable supply chain bottlenecks that would […]

When Markets Undermine Reliability

Air conditioners are running at full throttle as summer descends in all its sticky, suffocating glory. As those ACs kick on, electricity demand is creeping up, potentially hitting record levels in some states. In Texas, as temperatures climb towards triple digits, customers are wondering if the AC – and a reliable flow of power – […]

Subsidizing Grid Unreliability

As the share of coal power on the Texas grid continues to decline and as greater reliance is placed on renewable sources of generation, Texans are crossing their fingers that they don’t face rolling outages this summer. There’s ample reason for concern. ERCOT, the state’s grid operator, is working with a razor-thin reserve margin of generating […]
