Statistics utilities are facing today
92% of all customer outages result from problems on thepower distribution system.
U.S. electric utilities spend about $18 billion per year ondiscovering root causes of outages.
The average age of a failed substation transformer is 18years with most transformers reaching 40 years of life.
U.S. loads will increase by 23% over the next 20 years.
Less than 10% of U.S. co-ops and municipal utilities havelaunched holistic smart grid initiatives.

Open & Layered softwarearchitectureWhen specifying software, look foropen architecture.
Know the platform of the solution(Windows vs Linux/Unix and thecosts of supporting this in terms of $,training and people)
Be wary of proprietarysoftware/hardware
Determine if software can connect tobasic systems, RTUs and relays
Can additional solutions be added oneasily?
Can it support CIP requirements?

Develop your own roadmap of where you want to be Think about flexibility, holistic, long-term and integrated approach
Watch out for point solutions that solve the immediate need but cant grow
Determine if the supplier will be there for you in 10 years
Determine any issues with your purchasing policies based on integration
requirements or add-ons from suppliers Use total cost of ownership as your comparison metric (ask for hourly prices and
see how expensive adding a new sub will be)
Be realistic about your staffs time and ability to install SCADA at a substation
after the vendor does one substation and trains your staff
