BTO and National Laboratories are conducting R&D and field testing to
advance key concepts that will shape grid-interactive buildings, including:
Grid-Interactive Buildings – select research & analysis activities
Developing analytical frameworks that fully value homes and buildings as flexible electric grid
resources, including valuing efficiency on a time-sensitive basis
Quantifying flexible building load potential to provide grid services and maximize demand
response capacity
Developing open source, scalable, transactive control systems that enable buildings to
provide grid services without decreasing performance
Conducting end-use load profile modeling across the U.S. building stock to inform energy
efficiency and demand response savings profiles for buildings and technologies

Cities and communities must
determine how to optimize
digital connectivity, energy
technology, smart infrastructure
to strengthen their resilience,
prosperity, affordability, livability.

Connected Communities – modeling
In partnership with the local electric
utility, DOE and its Oak Ridge
National Lab are creating ‘digital
twins’ of 169,000 buildings in
Chattanooga, Tennessee, to
determine energy, demand,
emissions, economic savings

Connected Communities – emerging U.S. examples
Connected Community elements are emerging in many U.S. cities, including:
Alabama Power Smart Neighborhood Pilots: 62 new
smart homes connected to transactive community
microgrid. DOE, Southern Co. partnership.
Jasper Community (Arizona): Proposed 2,900 homes
with grid interactivity and 23MWh energy storage bank to
aggregate & optimize energy at neighborhood scale.
Brooklyn-Queens Demand Management Pilot (NYC):
ConEd pilot to meet expected 69MW shortfall and defer
$1.2B in costs through energy storage, DR, and solar.
