  • Energy when it is Needed
    John Frederick
    Senior Vice President
  • Energy Quiz
    Question:
    When is wind production the highest?
    Answer:
    70% of wind production happens at night
  • Energy Quiz
    Peak Solar
    Production
    Question:
    When is solar production the highest?
    Answer:
    80% of all solar production happens between 9am and 2pm
  • Energy Quiz
    Peak Solar
    Production
    Question:
    When do electric utilities experience peak daily demand?
    Answer:
    Peak electrical demand typically occurs between 4pm and 7pm
    Utility
    Peak Demand
  • Energy Quiz
    Final Question:
    How many states have passed Renewable Portfolio Standard Laws?
  • Energy Quiz
    Answer:
  • Utility Scale Energy Storage Technologies
    • Despite recent advances in “Utility Scale” storage technology, all current technologies cost between $1,000 and $2,500 per KWh*
    • Distributed, utility controlled, customer sited energy storage can be below $1000 per KWh
    *$1,000 and $2,500 per KWh includes all balance of system components (i.e. power electrics, switch gear, etc)
  • Distributed Storage Value Curve
  • Value of Storage for Utilities

  • Community Energy Storage Value Streams
    CES provides many value
    streams versus bulk storage
    Energy Storage for the Electricity Grid: Benefits and Market Analysis Guide
    Jim Eyer and Garth Corey
  • Solar Peak Shifting…
    Typical Residential Household Using 40 kWh per day
    “On Peak” Period From 2pm to 8pm
    Demand
    kWh
    time
    Silent Power stores the excess Solar PV for use during the “On Peak” period
  • Residential Energy Storage Value Streams
    RES provides even more
    value streams
    Energy Storage for the Electricity Grid: Benefits and Market Analysis Guide
    Jim Eyer and Garth Corey
  • Substation Storage vs CES vs RES Analysis
  • Cost Advantages of RES vs CES
    RES is being installed as part of new Solar PV installations
  • CES Challenges
    • Shown here is the transformer at John Frederick’s home
    • John does not want his nice new landscaping disrupted with a CES device
    • John’s neighbor has a huge swimming pool that will consume all the CES backup energy when it is engaged
    • Integrating renewables at his location would be a challenge
    • Utility bears 100% of the cost for the CES device plus installation
  • OnDemand Energy Appliance….Features
  • Economics for Residential Energy Storage
    • Incremental cost to add storage to standard Solar PV system is $14,000
    • 30% federal investment tax credit applies to $14,000 incremental cost
    • Net cost of 10 kWh of storage is $9,800 ($980 / KWh)

  • Consumer Benefits for Residential Energy Storage
    • Backup power system for critical circuits
    • UPS switchover times
    • Continued solar production during grid outage
    • Improved solar system ROI
    - TOU/Feed-in tariff adoption

  • Residential Standby Power Facts
    • 2.3 % of the 73 million single family households in the United States have standby power*
    • Predominately in the top 50% of income households
    • The average installed cost of a residential standby generators is $6000-$7000
    • Over 31 million people lost power in 2008 according to Generac
    • Power outages cost homeowners $1.5 billion dollars each year**
    • Causes of Outages

  • Value of Storage for End Users
    Time of
    Use Pricing
    Time Of Use Pricing Examples
    • There is some value associated with end user energy arbitrage
    • anywhere from $118 to $352 per year using current rates
    • this could easily go to $400 to $800 per year
    • The real value for home owner is backup power
  • Market Potential for adding Storage to Residential Solar PV
    US Residential Solar PV Forecast
    • Adding a small amount of storage to every new residential solar install would have a big impact
    • Average Solar PV installation 4.7 kW
    • Average storage attached to each Solar PV installation is 10 kWh
    • Starting today (2010), adding storage to every new solar home would equal 5.5 GW through 2015
    New Solar PV Installs
    Megawatts of Storage
  • Market Potential for adding Storage to Commercial Solar PV
    US Commercial Solar PV Forecast
    • Adding a small amount of storage to every new commercial solar install would have a big impact
    • Average Commercial Solar PV installation 50 kW
    • Average storage attached to each Solar PV installation is 50kWh
    • Starting today (2010), adding storage to every new solar business would equal 6.14 GW through 2015
    Megawatts of Storage
    New Solar PV Installs
  • Communication & Aggregation
    MWh
    Number of Customers
  • Residential Energy Storage Pilots
  • SMUD Distributed Storage Project
    • SMUD believes that bulk and distributed storage will be needed in the long run
    • SMUD will be piloting both RES and CES
    • 3 CES devices
    • 15 RES devices
    • Other Project participants include GridPoint, Navigant Consulting, Sunpower, and Saft
    • Silent Power is working with SMUD on economics for full scale deployment
  • Summary
    • Residential Energy Storage should be part of every utility’s energy storage portfolio
    • Residential Energy Storage provides the maximum number of values streams for both the utility and end user. Highest societal benefit.
    • Residential Energy Storage is the lowest cost form of utility energy storage
  • Thanks for your time
