commercial system very quickly. I think that's the way
the buildings of the future are going to be.
Deru: I actually want to touch a little bit on Ben's comment
that we should be looking at the overall system
and trying to minimize the storage to meet whatever
requirements we think are important-if it's cost, if it's
carbon, if it's land use or water use. Whatever that is,
that optimal system design is going to determine how
much storage and where we need it.
Ideally, the storage is going to be very efficient. It's
going to be integrated with our systems, and it will provide
the loads we need. We have buildings, and we have
systems we put in those buildings for a reason. We want
to use them to do whatever we're trying to do. Putting
the storage where it will provide those services in a resilient
and robust way to have a clean energy future-if
that's our desire-then hopefully that's what we'll be able
to do. The storage is going to be, as Ram said, a utilities
plan for a long future.
Narayanamurthy: I think I'm going to approach it
from, maybe, a slightly different angle. I would like to

see us tighten up our building codes, get new metrics
in-whether that's peak demand of a building as a metric,
carbon as a metric, move to a site energy metric
away from a source energy metric-because the source
energy metric makes less and less sense in a highly
renewable grid. The grid is already moving, probably
much faster than buildings, toward a zero carbon
future.
If you can tighten that up and then you let the market
figure out how to integrate storage, maybe have restrictive
requirements for both thermal and electrical storage
in buildings-thermal could be active or passive-and
see if we can drive it through the building code cycle
so we can drive more storage into our buildings, that's
really going to help the distribution grid as well as growing
the demand for flexibility that's required. I know we
have taken some steps in that area, but I would love to
see us do more.
Torcellini: Thank you for taking the time to share your
thoughts on energy storage and provide your viewpoints
into the rapidly evolving technology space.
