EnergyInternetValueProposition

• Commercial Open Architecture Software Platform

• Monitor and Control energy systems (HVAC, lighting, plug loads)

• Extendible to solar PV systems in micro-grid environments.

• Help buildings participate in Demand Response programs through OpenADR

=+• Immutable, secure

record of P2P and Negawatt trading transactions

• Proprietary bidding algorithms to maximize participants’ utility from trading

• Automated transactions governed by smart contracts executed in near real-time (1 hour ahead)

The Energy Internet

Homeowners, utilities, microgrids and other distributed energy resource owners can:

• Transact on a trusted common platform

• Fully integrate building control into P2P and negawatt trading contexts

• Harness the value of demand response initiatives and microgrid-level PV production while maintaining comfort of individual buildings

Building Energy Management

Microgrid Energy Management

Local Energy Market

+• Monitor and Control energy

resources in Microgrid (battery storage, PVs, other DERs)

• Create programs and involve customers in the energy consumption, generation, and management process

• Demand Response

• Data analytics & energy insights applicable to local communities
