Rapid increases in electricity demand challenge both generating unit and system operators

Rapid increases in electricity demand challenge both generating unit and system operators | Electricity Market | Scoop.it

Energy Information Administration - Because supply and demand for electricity must balance in real-time, rapid changes in demand create operational challenges for the electric system and generating unit operators.

ProviderPower's insight:

Meeting this increasing demand can be stressful for system and generating unit operators because system operators need to order generators to ramp up efficiently while maintaining reliability.


Also, this steepest ramp occurred during the spring low-demand season when there are fewer generating units available for ramping because of unit maintenance outages.


  • While coal-fired units in this instance provided about 70% of the increase in capacity during the peak ramp hour, natural gas-fired capacity increased its output at a higher rate than coal capacity (19% to 16%).
  • This difference is because SPP relies more on natural gas-fired capacity for quick ramping and the output of natural gas generators is starting from a smaller base than coal generators.
  • Wind output was flat during the peak ramp hour and declined after that.

Utility Nightmares: Distributed Generation and Halving Electricity Consumption

Utility Nightmares: Distributed Generation and Halving Electricity Consumption | Electricity Market | Scoop.it
While many utility executives attribute much of their predicted market challenges to the rise of photovoltaics and net metering, they actually have much more to worry about.
ProviderPower's insight:

In North America, 40 percent of respondents believed that utility companies' means of making a profit will see major changes over the next two decades.  A strong majority — 82 percent — of North American respondents also said future energy needs will be met by a mix of traditional centralized generation and distributed generation, which feeds power from a mix of sources.
