The Leader in Grid Tied Residential Energy Storage

Blake F. Richetta Senior Vice President, sonnen Inc. Blake.R@sonnen-batterie.com

#1. Solve a Problem: The inherent challenge presented to the electricity grid as a result of the intermittent and unpredictable nature

• f renewable energy, can be mitigated

by a distributed network of energy storage systems “Green grid reliability requires flexible resource capabilities” “Reliability requires balancing supply and demand”

• California ISO

Why Energy Storage?

Challenges: 1. The rapid downward ramp during peak renewable production hours and the rapid upward ramp, to evening peak 2. Grid stress, voltage fluctuation or loss, inefficiency 3. Less than ideal carbon offset (potentially) Result: Electricity Grid requires a resource mix that can react quickly to rapid changes

Clean Energy System that is smart, designed for a high level of self- utilization, coupled with properly managed grid export and support. The objective is to flatten load curve, while stabilizing and adding flexibility to the grid Enabling a true “clean energy future”

Why Energy Storage? Grid Harmonization

#2. Add Value! A distributed network of behind the meter energy storage systems can help solve the challenges associated with “peak demand” on the grid

Why Energy Storage?

#2. Add Value! Building a decentralized “virtual power plant” can be less expensive, more efficient and significantly cleaner than building a traditional “peaker plant” or new substation Distributed energy storage can represent a viable “non wire alternative” to traditional grid infrastructure upgrades Both of the above examples can lead to substantive T&D and Peak Demand investment deferrals

Why Energy Storage?

#1. Daily cycling

• Offset “Peak Demand Periods”
• Evening Peak, Morning Peak
• Aka “Time of Use”
• Aka “Peak Flooding” - Energy
• Stored sunlight energy or Grid

load shift energy

• Environmental benefit + potential

financial benefit

• Avoid TOU Peak Rates “TOU

arbitrage”

• Run your home on solar energy

24 hours a day:

• “24 hour Solar Self-Consumption”

aka “Self-Consumption”

• Environmental + potential

financial benefit

• Energy Independence
• Peak Shaving to offset Demand Charges

Energy Storage Applications

• Harness sunshine for 24-hour use
• When the sun is no longer shinning, run your home on stored sunshine
• “Get through the night on stored sunlight!”

Technical Processes Required for “Daily Cycling” Solar Time Shifting

Energy Storage Applications

8am-11am “Partial Peak” 12pm-3pm “Afternoon Peak” 5pm-9pm “Evening Peak” 12am – 6am Middle of the Night “Off Peak” Example Load Curves: 1. Cooler Environment: Morning peak, afternoon “valley” and evening peak 2. Moderate Environment: Morning rise, afternoon peak, evening peak 3. Hot Environment : Afternoon & early evening peak

#3. Grid Services via the aggregation

• f Distributed Energy Storage

Resources

1. Virtual Power Plan (VPP): 1. Demand Response

• Offset grid peak periods

(utilizing stored sunlight or grid load shift energy)

• Peak Shaving
• Receptacle for excess

renewable production 2. Flexible Ramping 3. Capacity Firming, Dynamic Capacity 2. Grid Infrastructure Stabilization: 1. Frequency Regulation 2. Voltage Response and Reactive Power support 3. Resiliency - Emergency Backup

4. Situational Intelligence

Energy Storage Applications

For the Utility, the choice is simple:

• Live with the expansion of renewables
• n the grid, “painfully”

Or..

• Embrace, control and utilize the

expansion of renewables, to add value to the electricity grid

Energy Storage Applications

• Decentralized
• Decarbonized
• Digitalized

Usher in the Energy Transition, with Clean Tech!

“The Electricity Grid

• f the Future”

• Critical role of Distributed Energy

Resources (DERs) and Distributed Energy Resource Management Systems (DERMS)

• Generation
• Storage
• Significant renewable footprint on the

electricity grid

• Residential
• Commercial
• Utility Scale

“The Utility of the Future”

• Significant percentage of energy will

be self-produced by “prosumers” and will either be self-consumed or exported when most useful

“The Utility of the Future”

• Smart Consumption and Managed

Production

• Increased significance of smart

home and building energy management systems and appliances, specifically for the purpose of “demand control” and “load balancing”

“The Utility of the Future”

• Agile Utility manages the

transactional platform between “prosumers,” supplementing where needed

“The Utility of the Future”

• Electricity Grid consists of a fleet of low-

carbon footprint, efficient, centralized base-load power plants, coupled with storage

• Aforementioned power-plants will be

Complemented by a large network of decentralized and distributed energy resources, specifically renewable generation coupled with storage – both Front-of-Meter and Behind-the-Meter, ready for rapid response!

• Eliminating the need for Peaker Plants

“The Electricity Grid

• f the Future”

• The electrification of transport will

play a significant role as grid infrastructure will be utilized to charge EVs, focusing on “off-peak” hours

• Conversely, EV battery packs will play

a greater role in overall grid management

“The Electricity Grid

• f the Future”

• Smooth, efficiently managed

relationship between Production and Consumption
