  40. Background Tremendous response to OPA FIT program has created generation connection capacity constraints across Ontario •  Ontario transmission and distribution system designed to deliver electricity from central generation plants to customers •  Tremendous response to FIT program has put new stresses on system that were not foreseen when system was designed and constructed •  Given its expansive service territory and suitability for wind and PV, Hydro One received significant portion of connection requests •  Given the topology of Ontario’s electricity system, constraints on Hydro One transmission and distribution network can cascade down to Local Distribution Companies (LDCs)Confidential and Proprietary, ©2011 Navigant Consulting Ltd. 41Do not distribute or copy
  41. Current Situation: Available Connection Capacity There are three primary system constraints; in simple terms the available capacity is driven by the most restrictive of these constraints Es*mated  available  connec*on  capacity  on  en*re  Hydro  One  system*   Short  Circuit  Capacity  reflects  how  much  fault  current  the  various   Thermal  Capacity  reflects   system  components  (eg,  circuit  breakers,  etc.)  can  handle   how  much  current  the   wires  can  carry   Reduces  connec*on  capacity  by  ~9,000  MW   Minimum  Load  is  generally  driven   by  transformers  than  cannot  “run   backwards”  (eg,  supplying  power   upstream  instead  of  downstream)   Reduces  capacity  by    ~5,000  MW   NB.  Other  constraints  and   conOngency  consideraOons   would  likely  reduce  this   capacity  further   * Navigant estimate based on information from Hydro One website, does not reflect network topology effectsConfidential and Proprietary, ©2011 Navigant Consulting Ltd. 42Do not distribute or copy
  42. Current Situation: Available Connection Capacity versus Connect Requests The generation capacity wanting to connect significantly exceeds the available connection capacity on the system Available  connec*on  capacity    vs.  connec*on  capacity  requested   * Navigant estimate based on information from Hydro One and OPA websiteConfidential and Proprietary, ©2011 Navigant Consulting Ltd. 43Do not distribute or copy
  43. 1 Overview of Navigant 2 Background 3 What’s Happening 4 One Potential Opportunity©2011 Navigant Consulting Ltd. 44
  44. What’s Happening Hydro One and industry are working collaboratively to better understand and address the constraints •  Hydro One and CanSIA have established a Working Group and have jointly retained a consultant to explore contribution of PV to short circuit levels. Inverter manufacturers are also involved •  Hydro One is said to be revisiting its “7% rule” (microFIT DG cannot exceed 7% of maximum load) and will be releasing its findings shortly —  This rule reflects Hydro One’s interpretation of an IEEE standard and provides a safe uniform level for application across Hydro One network —  Going beyond “safe uniform level” would require tremendous resources and detailed local information, neither of which are readily available •  CanSIA has proposed an inverter workshop so all parties can better understand the performance characteristics of inverters —  Proposed testing of inverters under different circumstances •  Growing recognition of high voltage issues and impacts on inverter operation Industry  knows  more  now  than  it  did  a  year  ago;  will  know  even  more  a  year  from  now   It’s  very  complicated!  ©2011 Navigant Consulting Ltd. 45
  45. 1 Overview of Navigant 2 Background 3 What’s Happening 4 One Potential Opportunity©2011 Navigant Consulting Ltd. 46
  46. Potential Opportunity: Coincidence of PV Output and Feeder/Transformer Loading Minimum load constraints reflect inability of many Hydro One transformers to handle “reverse flow”. But, PV output is generally lowest at times of minimum load Illustra*ve  bus  loading  vs.  PV  output  (spring  day)  Confidential and Proprietary, ©2011 Navigant Consulting Ltd. 47Do not distribute or copy
  47. Potential Opportunity: Coincidence of PV Output and Feeder/Transformer Loading The “7% Rule” (PV = 7% of maximum feeder loader) provides a significant safety margin against reverse flow Dura*on  curve  of  bus  loading  vs.  simultaneous  PV  output  (@7%   of  peak)  over  full  year  (8760  hours)   PV  output  always  significantly  less   than  load  even  in  low  demand   periods  for  this  par*cular  bus  Confidential and Proprietary, ©2011 Navigant Consulting Ltd. 48Do not distribute or copy
  48. Potential Opportunity: Coincidence of PV Output and Feeder/Transformer Loading 8-fold increase in PV capacity to 56% of maximum feeder loader would result in some reverse flow hours, but not many Dura*on  curve  of  bus  loading  vs.  simultaneous  PV  output     (@56%  of  peak)  over  full  year  (8760  hours)   PV  output  exceeds  load  for  only   28  hours  in  en*re  year   For  this  bus,  28  MW  increase  in  PV  capacity  could  be  enabled  through  “Smart  Grid”   technology  that     1)  monitors  load  and  PV  output,  and  2)  controls  PV  connecBon  to  eliminate  reverse   flow  as  necessary   How  much  would  you  be  willing  to  pay  49 this  allowed  you  to  connect  your  project?  Confidential and Proprietary, ©2011 Navigant Consulting Ltd. if  Do not distribute or copy
  49. Conclusions •  Tremendous response to OPA FIT program has created generation connection capacity constraints across Ontario •  Available connection capacity is driven by the most restrictive of several constraints (thermal, short circuit, minimum load and others) •  The capacity of the generation wanting to connect significantly exceeds the available connection capacity on the system •  Hydro One and industry are working collaboratively to better understand and address the constraints •  Many opportunities for “smart” solutions to enable connections beyond “safe uniform” level, but solutions need to be bulletproof It’s  very  complicated!  Confidential and Proprietary, ©2011 Navigant Consulting Ltd. 50Do not distribute or copy
