Acelerex has integrated the REX Data Services platform into the REX Grid Automation platform to provide residential customers with actionable insights into retail energy and demand charges for their in-home distributed energy resource. By analyzing weather patterns, peak load data, and historical rate structures, homeowners can optimize their energy usage and reduce costs by deploying REX on their solar, storage, EV, and/or backup generation hardware.
Services for Battery Energy Storage Systems (BESS)
- Time-of-Use Price Following: Charge your BESS when electricity prices are low and discharge when prices are high to maximize savings.
- WattTime/SGIP: Align your energy usage with sustainability goals by charging during low CO2 emissions periods and discharging during high CO2 emissions.
- Demand Peak Shaving: Minimize utility demand charges by discharging during peak demand hours and charging during solar generation or low cost hours.
- Demand Response (utility program): Participate in demand response programs by charging during solar hours and discharging during grid demand response windows (e.g., 4 PM – 9 PM).
- Distribution Hosting Capacity: Prevent backfeed into the transmission system by charging during solar hours.
- Baseload Power: Ensure a steady net injection to the grid by managing solar production and BESS discharge levels.
- VPP Controllability: Integrate BESS into Virtual Power Plant (VPP) networks, enabling remote signals for aggregation and state-of-charge (SoC) enforcement.
EV Charging Integration
- Time-of-Use Price Following: Charge your electric vehicle (EV) during low electricity price periods for cost efficiency.
- WattTime/SGIP: Leverage solar power to charge during low CO2 marginal emissions times.
- Demand Response (SCE Power Saver Rewards Program): Block grid charging during demand response periods while ensuring EV readiness through solar charging.
- Self-Consumption: Charge your EV exclusively with excess solar generation, reducing grid reliance.
Seamless Technology Integration
Acelerex integrates with cutting-edge technologies like Sol-Ark Inverters, EnelX JuiceBox, and Wallbox to provide comprehensive observability of:
- Battery state
- Home energy demand
- Solar generation
- EV charging
With support for scheduling BESS and EV operations through financial and technical signals, Acelerex Data Services ensures optimized energy management. Control your system via the onsite REX Appliance or through Acelerex’s REX Cloud interface.
Use Case
Customer Profile: A suburban homeowner with a 10kW rooftop solar system, a 13.5kWh BESS, and an EV.
Challenge: Managing retail energy costs, aligning energy usage with sustainability goals, and participating in demand response programs to maximize savings.
Solution:
- The BESS is programmed with Time-of-Use Price Following, charging during low-price periods (e.g., midday solar hours) and discharging during peak-price evenings.
- The homeowner participates in the Demand Response (SCE Power Saver Rewards Program), allowing their BESS and EV to support grid stability from 4 PM to 9 PM.
- The EV charging is set to Self-Consumption, utilizing only excess solar power.
- WattTime/SGIP is activated, ensuring the system operates during low CO2 marginal emissions periods, reducing the home’s carbon footprint.
Outcome:
- 20% reduction in monthly electricity costs through optimized scheduling.
- Full utilization of solar generation with no backfeed into the grid.
- $300 annual savings from participation in demand response programs.
- Contributing to sustainability goals with reduced CO2 emissions.
