How Grid Engineers ID & Address Problems
What is the incidence and consequence of the problem the new technology is intended to address?Will the new technology actually reduce incidence and/or consequence, and if so, by how much? What conditions result in the problem, and where do these conditions exist?
What is the cost of the new technology relative to the incidence and consequence of the problem?
How does the cost/benefit ratio of the new technology compare to the cost/benefit ratio of other grid investment options? (risk-informed decision making)
Who should pay for the new technology? How can the new technology’s obsolescence best be planned for and managed?
