• Smart grids are always designed in response to the specific energy objectives faced by the countries. No unique model.
• The scope of regulators in setting the regulatory framework for smart grids investments will depend upon organizational structure issues.
• What is recognized as best regulatory mechanisms by the litterature is rarely adopted. This can lead to inefficiencies in the process of adopting the technology

2/ Organizational issue and the scope of the regulator
1: Classical roles of regulation :o Provide incentive for enhanced productive/innovative efficiency
o Extract part of the efficiency rent (limit the impact of information asymetry)o Enhance the quality of the utility.
2: Smart grids objectives-related regulation : coherence between the regulatory framework and the first drivers for SG investments
o Energy efficiency in California,o RES and DG integration in Gremanyo The adoption of smart meters for RTP in Illinoiso The elimination of DNOs forclosue and the stimulation of retail competition in
the UK
3/ Main elements characterizing a smart grids oriented regulation:
California Germany Illinois UK
Productive & innovative efficiency
• CoS + Revenue cap• Smart grids expenses recorded as capex.
• CoS + Revenue cap• Smart grid expenses recorded as non controlable costs.
•CoS + PBR• Ex ante decision about smart grids investments.
• Menu of contract + Revenue cap regulation.
Rent extraction • 10% of SG underspending redistributed to the utilities.• Progressive revenue sharing mechanism based on benchmark RoE.
• No mechanism.• But future implementation of yardstick mechanim when regulatory scheme is more mature.
• Symetrical revenue sharing mechanism based on benchmark RoE.
Equalizing incentive with symetrical sharing based on the menu of contracts.
Enhance the quality
• Performance-based indicators
• 3 indicaors reflecting the quality of the load.
•7 performance indicators with reward/penalty incentive that directly rely on AMI deployment.
• Consumer-based incentives.
Smart grid-specific regulatory features
• Revenue cap is recognized as « DSM friendly » + decoupling mechanisms• 19 SG metrics.
• Expansion factor for DG-related expenses (shallow method of integration)
• 60 SG metrics • Implementation of the Data Communication Company.•RIIO@20
Concluding remarks:
It is paramount to have a stable long term smart grid strategy and to keep a coherence between the stated objectives and what is implemented. Questions the role of politics over the different mandates.
Tradeoff between incentives to invest and incentives to reach a higher level of efficiency. With the multiplication of countries adopting SG technology, more stringent efficiency incentives should be implemented as regulators obtain feedbacks and learning effects.
Smart grids technology, independently from its first purpose of adoption is likely to enhance the performance and quality of the grid. This should in turn translate into strengthened performance-based financial incentives. Avoid too numerous and burdensome metrics.
The question of smart grid technology « behind the meter » has to be studied through its effects on new entrants, particularly on countries where the process of market opening is underway (California).
