FLEXIBILITY: HOW DO WE MEASURE IT?
HOW DO WE INCENTIVIZE IT?

Defining the Problem:
“ACCESSING SOURCES OF SYSTEM FLEXIBILITY
IS ONE OF THE MOST CRITICAL STEPS IN
ACHIEVING HIGH PENETRATION OF VARIABLE
GENERATION..AT EVERY POWER SYSTEM SCALE” Source: NREL et.al
In addition to capacity, system planners are now concerned about the composition of new capacity
• Ramp rates, minimum stable levels, ability to provide reserves
Increasing the penetration of renewables is going to require improved system
flexibility

FLEXIBILITY: HOW DO WE MEASURE IT?
HOW DO WE INCENTIVIZE IT? • “IN NORDEL IT IS CLEAR THAT SUFFICIENT CAPACITY FROM
HYDRO AND CHP ARE ALREADY DEPLOYED”
• “IN THE IBERIAN PENNINSULA A WELL BALANCED COMBINATION OF HYDRO, PUMPED STORAGE AND CCGTs IS REALIZED..”
• “IN MANY COUNTRIES, IT IS CLEAR THAT THEY HAVE PREPARED THEMSELVES TO OPERATE AS FLEXIBLE POWER SYSTEMS , AS THEY RELY ON STRONG INTERCONNECTIONS AND SELF SUPPLY WITH HYDRO, PUMPED STORAGE AND CCGTs TO PROVIDE SYSTEM FLEXIBILITY”
