* What obligations will regulators request from utilities to
provide infrastructure support
to mobility electrification?
* What new capabilities will engineers need to design, build,
and operate the new grid?

Thanks to the capabilities and volunteerism of our membership, there is
no doubt that we will succeed in transforming the grid!

* more sophisticated modeling
techniques required of the new
grid-operating conditions.
✔ Utilize the strengths of the IEEE
(its knowledge base, robust technical deliberations, and credibility with policy makers) and
engage in the difficult policy,
business, and regulatory questions, highlighting gaps within
the industry that need technical
direction and guidance. Support
policy makers with a realistic
view of the feasibility of the hybrid grid.
✔ Ask the hard questions!
* Who will pay for the foundational system (wires and generation) that modern economies depend on? How will reliability be
ensured?
* What new technical and engineering solutions will be required to guarantee that this
more complex grid will operate
safely and reliably?
* When will this become the new
normal, and what is the timeline?
* What skills will the workforce of the future need?
* What is the impact of climate
change on grid planning, design, operation, and overall
resilience?
* What are the next standards
and metrics that need to be addressed?
* What is the role of emerging
technologies including the Internet of Things and transactional energy?
* How is customer choice influencing the energy system, such
as distributed energy resource
aggregation, smart cities, and
community choice aggregation?
* Where will efficiencies be
gained or lost?
* Why must we adapt a new design of wholesale and retail
electricity markets while ensuring reliability?
* What roles will we play in the
new electricity future?
