"The Future is out there somewhere; we just have to make sure we get the best one"

"There are an infinite number of ways of running an Electricity Supply system badly"

Electricity delivery is Unique as an Energy vector.  There are no appropriate analogies.   It requires that you get it to the Right Place at the Right Time and that will be (Laws of Conservation of Energy) at the Exact Rate (Power) required. 
Thus tight matching of Generation Power to Expected Demand Power is required.
While maintaining Security (MW flow limits), Stability and Voltage (MVAr provision) at all points. While covering for any one of the large number of Credible faults occurring at any instant. 


The way in which Electricity is to be supplied is subject to radical change. Distributed and Renewable Generation, together with Demand Management, is being promoted to reduce the use of central fossil fired plant, increase efficiency in delivery of energy and reduce emissions.

By Low/Negative Carbon Low /Negative Price Synthetic Gas in Hybrid Energy Production (Electricity + Heat/Cool) systems to provide the necessary Flexibility to accommodate a higher penetration of Variable Renewable Generation.  With the latest mechanism for ElectroThermal Energy Storage. 

With the Siberian Heat Anomaly giving the Risk of Fossil Methane Release to Accelerate Warming.
“We have a Need, a Need for Speed”

However, this will only be achieved if all resources are properly monitored and controlled within a new framework for electricity supply management. Any electricity supply system is always in instantaneous Power balance; the wires hold no storage and electricity moves at the speed of light from Alternator to Appliance across the system.  We need to recognise the need for continuous tight matching of generation power to demand power and the associated requirement for accurate prediction.  Both power and time are crucial factors.

The Energy Central Power Industry Network is based on one core idea - power industry professionals helping each other and advancing the industry by sharing and learning from each other.

If you have an experience or insight to share or have learned something from a conference or seminar, your peers and colleagues on Energy Central want to hear about it. It's also easy to share a link to an article you've liked or an industry resource that you think would be helpful.
