A Better Measure for Profitability

A new way to measure what matters most: how close a unit comes to meeting its total potential profit.

Approximately 65 percent of capacity additions in the last few years have been gas-fired, combined-cycle units. Recent market conditions have been hard on these new resources, which have suffered from significantly low capacity factors. A better metric would measure a unit's ability to capture peak prices while minimizing shoulder period and off-peak losses. Furthermore, it would measure the extent to which a unit dispatches according to favorable market conditions.

Renewable Energy

Mandatory portfolio standards have different implications for different technologies.

Renewable Energy:

Mandatory portfolio standards have different implications for different technologies.

The federal government and several state governments are considering programs to increase the share of electricity produced by renewable generation resources to 20 percent or more. If these programs are implemented and pursued successfully, they will trigger a dramatic change in the role of renewable generation and the requirements placed upon it by the market.

Combining real-time usage data with the newest technology can earn benefits for utilities.

Some amount of confusion on the part of end-users of electricity is inevitable as the electricity industry evolves. Confusion seems to be a necessary ingredient of change. At PJM Interconnection, we see fusion as the answer to confusion. First is the fusion of technology-both computing and communications technology-with the electric industry.

Generation Reserves: The Grid Security Question

A cost-benefit study shows the value of adding synchronized generating reserves to prevent blackouts on the scale of Aug.14.

A cost-benefit study shows the value of adding synchronized generating reserves to prevent blackouts on the scale of Aug.14.

If nothing else, the blackout of Aug. 14 showed just how physically vulnerable the electric transmission network has become to problems that begin at a very localized level. That vulnerability stems in part of the greater volume of long-distance transactions imposed on the grid by today's power industry.

Water Heaters to teh Rescue: Demand Bidding in Electric Reserve Markets

With just a few changes in reliability rules, regulators could call on consumer loads to boost power reserves for outages and contingencies.

With just a few changes in reliability rules, regulators could call on consumer loads to boost power reserves for outages and contingencies.

 

In proposing a standard market design (SMD), the Federal Energy Regulatory Commission (FERC) makes clear that it wants customers to participate in wholesale power markets, such as by bidding an offer to curtail consumption, increase supply, and reduce upward pressure on prices.

"We believe in the direct approach of letting demand bid in the market," says FERC.

How software controls can bridge the gap between wholesale market prices and consumer behavior.

As ideas go, a microgrid is nothing new. Think of steam pipes for district heating in older urban cores. But add a few software controls, and the possibilities grow.

Large-Scale Green Power: An Impossible Dream?

Chasing after windmills and photovoltaics could well be the stuff of fiction.

Chasing after windmills and photovoltaics could well be the stuff of fiction.

Wind and solar cells (photovoltaics or PVs) are two renewable energy technologies that many hope will eventually provide the United States with massive amounts of clean, sustainable electric power for the indefinite future. Indeed, it is often suggested or implied that the United States can look to a future where most, if not all electric power can be provided by wind and photovoltaics [1, 2].
