Energy when it is Needed, John Frederick

  1. 1. Energy when it is Needed<br />John Frederick<br />Senior Vice President<br />
  2. 2. Energy Quiz<br />Question:<br />When is wind production the highest?<br />Answer:<br />70% of wind production happens at night<br />
  3. 3. Energy Quiz<br />Peak Solar<br />Production<br />Question:<br />When is solar production the highest?<br />Answer:<br />80% of all solar production happens between 9am and 2pm<br />
  4. 4. Energy Quiz<br />Peak Solar<br />Production<br />Question:<br />When do electric utilities experience peak daily demand?<br />Answer:<br />Peak electrical demand typically occurs between 4pm and 7pm<br />Utility<br />Peak Demand<br />
  5. 5. Energy Quiz<br />Final Question:<br />How many states have passed Renewable Portfolio Standard Laws?<br />
  6. 6. Energy Quiz<br />Answer:<br />
  7. 7. Utility Scale Energy Storage Technologies<br /><ul><li>Despite recent advances in “Utility Scale” storage technology, all current technologies cost between $1,000 and $2,500 per KWh*
  8. 8. Distributed, utility controlled, customer sited energy storage can be below $1000 per KWh</li></ul>*$1,000 and $2,500 per KWh includes all balance of system components (i.e. power electrics, switch gear, etc)<br />
  9. 9. Distributed Storage Value Curve<br />
  10. 10. Value of Storage for Utilities<br />NPV<br />$/kW<br />Distribution Value<br />Dynamic VAR Support<br />~150<br />Improved Service Reliability<br />(site dependent)<br />~250<br />Generation Value<br />Firming & Shifting Renewables<br />(source dependent)<br />~650<br />~150<br />Energy Arbitrage<br />Frequency Regulation and other Ancillary Values<br />(large variability)<br />~450<br />Distribution Capital Deferral<br />(site dependent)<br />~850<br />Generation Capacity<br />~500<br />
  11. 11. Community Energy Storage Value Streams<br />CES provides many value<br />streams versus bulk storage<br />Energy Storage for the Electricity Grid: Benefits and Market Analysis Guide<br />Jim Eyer and Garth Corey<br />
  12. 12. Solar Peak Shifting…<br />Typical Residential Household Using 40 kWh per day<br />“On Peak” Period From 2pm to 8pm<br />Demand <br />kWh<br />time<br />Silent Power stores the excess Solar PV for use during the “On Peak” period<br />
  13. 13. Residential Energy Storage Value Streams<br />RES provides even more<br />value streams<br />Energy Storage for the Electricity Grid: Benefits and Market Analysis Guide<br />Jim Eyer and Garth Corey<br />
  14. 14. Substation Storage vs CES vs RES Analysis<br />
  15. 15. Cost Advantages of RES vs CES<br />RES is being installed as part of new Solar PV installations<br />
  16. 16. CES Challenges<br /><ul><li>Shown here is the transformer at John Frederick’s home
  17. 17. John does not want his nice new landscaping disrupted with a CES device
  18. 18. John’s neighbor has a huge swimming pool that will consume all the CES backup energy when it is engaged
  19. 19. Integrating renewables at his location would be a challenge
  20. 20. Utility bears 100% of the cost for the CES device plus installation</li></li></ul><li>OnDemand Energy Appliance….Features<br />
  21. 21. Economics for Residential Energy Storage<br /><ul><li>Incremental cost to add storage to standard Solar PV system is $14,000
  22. 22. 30% federal investment tax credit applies to $14,000 incremental cost
  23. 23. Net cost of 10 kWh of storage is $9,800 ($980 / KWh)</li></ul>Silent Power<br />OnDemand <br />Energy Appliance<br />with 10 KWh of <br />battery storage <br />Lithium Ion battery example<br />
  24. 24. Consumer Benefits for Residential Energy Storage<br /><ul><li>Backup power system for critical circuits
  25. 25. UPS switchover times
  26. 26. Continued solar production during grid outage
  27. 27. Improved solar system ROI </li></ul>- TOU/Feed-in tariff adoption<br />Silent Power<br />OnDemand <br />Energy Appliance<br />with 10 KWh of <br />battery storage <br />
  28. 28. Residential Standby Power Facts<br /><ul><li>2.3 % of the 73 million single family households in the United States have standby power*
  29. 29. Predominately in the top 50% of income households
  30. 30. The average installed cost of a residential standby generators is $6000-$7000
  31. 31. Over 31 million people lost power in 2008 according to Generac
  32. 32. Power outages cost homeowners $1.5 billion dollars each year**
  33. 33. Causes of Outages </li></ul>*Source: NPD 2008 Generator Owner Study<br />Energy when it’s needed<br />**Source: Propane Education & Research Council<br />
  34. 34. Value of Storage for End Users<br />Time of<br />Use Pricing<br />Time Of Use Pricing Examples<br /><ul><li>There is some value associated with end user energy arbitrage
  35. 35. anywhere from $118 to $352 per year using current rates
  36. 36. this could easily go to $400 to $800 per year
  37. 37. The real value for home owner is backup power</li></li></ul><li>Market Potential for adding Storage to Residential Solar PV<br />US Residential Solar PV Forecast<br /><ul><li>Adding a small amount of storage to every new residential solar install would have a big impact
  38. 38. Average Solar PV installation 4.7 kW
  39. 39. Average storage attached to each Solar PV installation is 10 kWh
  40. 40. Starting today (2010), adding storage to every new solar home would equal 5.5 GW through 2015</li></ul>New Solar PV Installs<br />Megawatts of Storage<br />
  41. 41. Market Potential for adding Storage to Commercial Solar PV<br />US Commercial Solar PV Forecast<br /><ul><li>Adding a small amount of storage to every new commercial solar install would have a big impact
  42. 42. Average Commercial Solar PV installation 50 kW
  43. 43. Average storage attached to each Solar PV installation is 50kWh
  44. 44. Starting today (2010), adding storage to every new solar business would equal 6.14 GW through 2015</li></ul>Megawatts of Storage<br />New Solar PV Installs<br />
  45. 45. Communication & Aggregation<br />MWh<br />Number of Customers<br />
  46. 46. Residential Energy Storage Pilots<br />
  47. 47. SMUD Distributed Storage Project<br /><ul><li>SMUD believes that bulk and distributed storage will be needed in the long run
  48. 48. SMUD will be piloting both RES and CES
  49. 49. 3 CES devices
  50. 50. 15 RES devices
  51. 51. Other Project participants include GridPoint, Navigant Consulting, Sunpower, and Saft
  52. 52. Silent Power is working with SMUD on economics for full scale deployment</li></li></ul><li>Summary<br /><ul><li>Residential Energy Storage should be part of every utility’s energy storage portfolio
  53. 53. Residential Energy Storage provides the maximum number of values streams for both the utility and end user. Highest societal benefit.
  54. 54. Residential Energy Storage is the lowest cost form of utility energy storage</li></li></ul><li>Thanks for your time<br />John Frederick<br />218.833.2135<br />jfrederick@silentpwr.com<br />
