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
