This session is part of the Clean Energy Regulators Initiative Webinar Programme.
Theme 1 - The Evolving Role of Network Regulators.
Module 1: Defining Structure and Roles of Regulators and Institutions
Power systems around the world are quickly evolving, and the role of power sector regulators is growing substantially more complex.
This webinar will provide an overview of global forces shaping power sector transformation, discuss the evolving role of the regulator to harness such forces, and then zoom-in on a particular transformative force – variable renewable energy – to discuss specific regulatory aspects and approaches.
This webinar is based on the reports "The Evolving Role of the Power Sector Regulator" and "An Overview of Variable Renewable Energy Regulatory Issues".

5. Power Sector Transformation is Happening
Today
• How countries envision, plan, and
regulate the power system is evolving.
• Long-held beliefs are evolving:
• Renewables are now a cost-
effective resource in many
locations and have been proven
not to require 1-to-1 reserves.
• Distributed generation is not
tantamount to the “utility death
spiral.”
• Planning, operational, and
regulatory strategies must evolve
but do not necessarily cost more
to implement.
• Networks can be cost-effectively
expanded from the bottom up.
• Utilities can sell more than just
electrons. Source: GridWise Alliance, U.S. Department of Energy

9. • Power sector regulators are frequently “where the rubber hits
the road”
• Regulators seek to:
– understand emerging trends in policy, technology, planning,
operations, and finance
– understand the technology implications of executing a policy
goal
– evaluate new technology solutions and how they impact existing
and emerging objectives
– navigate a multitude of evolving objectives (both legacy and
new)
• The objectives (and therefore the role!) of regulators is
quickly evolving
9
10. • Evolving regulatory objectives drive a new
role for regulators
– Existing objectives are growing more
complicated
– New suite of emerging objectives poses a
novel set of challenges
