What is the “smart grid?”
Wrong question Wrong answer: As many definitions as there are experts
Why all the interest in smart grid? Because current grid is outdated for what we need today Even more so for what we will need in the future
What sort of grid do we need? A more versatile and accommodating grid
![Page 4: What’s so smart about the smart grid? Presentation at IAEE Annual Conference 10 October 2011 Washington, DC Perry Sioshansi Menlo Energy Economics San.](https://reader036.fdocuments.us/reader036/viewer/2022062516/56649e605503460f94b5ab59/html5/thumbnails/4.jpg)
What sort of grid do we want?One that meets industry’s changing needs
A more enabling delivery infrastructure 1. More “reliable”, of course
Self-detecting, self-healing & plain “smart” 2. More “integrated”
Better balancing of supply & demand in real time 3. Capable of absorbing more renewable energy resources
Not 10%, 20% or 30% but 80% and more as in Germany 4. Allows integration of more distributed generation
CA Gov. Brown envisions 12 GW of DG by 2025 5. A “two-way” conduit connecting load & generation
No longer transferring central generation to major load centers 6. Allows “prices-to-devices” revolution
Smart prices to smart devices leading to smart energy usage

What is real and what is not?Sometimes lost in hyperbole
Renewables & DG – real Integration issues – real headaches EVs – two edged sword Dynamic pricing – regulators with back bone Smart devices – chicken & egg problem Taken together?
These are exciting times to be in industry
![Page 18: What’s so smart about the smart grid? Presentation at IAEE Annual Conference 10 October 2011 Washington, DC Perry Sioshansi Menlo Energy Economics San.](https://reader036.fdocuments.us/reader036/viewer/2022062516/56649e605503460f94b5ab59/html5/thumbnails/18.jpg)
Challenges & skepticismsNot everyone is convinced, for different reasons
Enormous up-front costs, elusive distant gains How do we finance, how do we distribute pains/gains?
Investment, regulatory & policy misalignment? Utilities, are by and large, heavily regulated
Technology – a lot more is expected Rapidly evolving on multiple fronts
Integration Huge issue – getting various components to “synergize”
Implementation & execution What is easy on paper is often difficult in practice
Managing public expectations Many more painful lessons to be learned along the way
![Page 19: What’s so smart about the smart grid? Presentation at IAEE Annual Conference 10 October 2011 Washington, DC Perry Sioshansi Menlo Energy Economics San.](https://reader036.fdocuments.us/reader036/viewer/2022062516/56649e605503460f94b5ab59/html5/thumbnails/19.jpg)
Few take away points
Current grid may not be smart but ain’t dumb Considered a significant “engineering achievement”
Rapid progress on multiple fronts Ample funding, R&D and entrepreneurial zest
Expect more setbacks/surprises Regulators reluctant to mandate dynamic pricing Small but vocal opposition to smart meters, data privacy, etc
No panacea, but a critical step in right direction Driven by desire for cleaner/greener/more efficient future
