The Journey of Electricity

Blackouts

Right now there are ~9,500 without power on Dominions Grid

Upgrading to intelligent systems

Benefits

• Self Healing• Predict Severe Weather Events• Detect Grid Overload• Make Appropriate Corrections• Reduced Operations, Generation, and

Maintenance Costs• Make 3-7 times the Investment back within a

few years.

Benefits

Demand Response and Variable Pricing

Emissions per Power Plant

Which Means the Savings are:

• SO2• 3.3 million tons/ yr./ plant x $344 per ton = ~$1

Billion!• NOx• 1.7 million tons/ yr./ plant x $850 per ton =

~$1.5 Billion!• CO2• 3.5 million tons/ yr/ plant x $16.27 per ton=

~$57 million

• Nearly $3 Billion Savings Per Plant Per Year in Emissions Costs

• With 20 Coal Fired Power Plants Run by Dominion=

• $60 BILLION PER YEAR

Jacquie L’etang mentioned it in her Journal of Business Ethics “Public relations summarize the activity as planned, deliberate communication directed towards target publics with the purpose of achieving an understanding.”
