Electricity system reliability has traditionally been guaranteed by planning the network with a high level of redundancy in both conventional generation and network capacity and by operating the system with relatively large security margins. In this way, end-customers in most of Europe have historically enjoyed a supply reliability close to 100%. However, the advent of renewable energy sources, whose weather-dependent production is variable and in part unpredictable, might change this paradigm. The question therefore arises as to what extent it is possible for a renewables-rich system to guarantee the same level of reliability of supply as before, and so what reliability level end-customers should expect.
Key discussion points
- Can a renewables-based system have the same reliability level as a “conventional” one. Is it about technical/technology aspects, cost, or both?
- Should the cost and value of reliability be made clearer to end-customers?
- Should we move towards a differentiated-reliability system?
- How reliable is the Smart Grid?

This is the 2nd panel discussion from IEEE's 2015 Summit on Secure Green Energy, held in Brussels on November 2015. Topics discussed include:
• Can a renewables-based system have the same reliability level as a “conventional” one. Is it about technical/technology aspects, cost, or both?
• Should the cost and value of reliability be made clearer to end-customers?
• Should we move towards a differentiated-reliability system?
• How reliable is the Smart Grid?
