More information

  • Assets can include load, generation or energy storage
  • Must be able to be automatically controlled
  • Temporary interruption of power supply should have minimal disruption to your business
  • Assets can have a variable operating profile and do not need to be available 24/7
  • Have a demand or generation output capacity of at least 100kW
  • Examples include cold stores, pumps, heating, ventilation and air conditioning (HVAC) systems, hot water and loads backed up by uninterruptible power supply (UPS) systems and gensets
Your existing control systems continue to have sole control of the assets. We install our VPP hub at your site which provides event signals as an input into your control system, which in turn controls the assets.
The electricity grid relies on scheduling supply to match demand in real-time. If a large generator or electricity cable fails, either additional supply or a reduction in demand is needed very quickly. A market operates to ensure sufficient ‘reserve’ capacity is available at all times. The reserve capacity can be provided by, for example, coal and gas power stations quickly increasing their output, or electricity loads switching off as soon as the unplanned grid event occurs.
The electricity grid is under most pressure when electricity demand is high, which often occurs on the coldest winter evenings, or when electricity supply is low, for example when the output from wind farms is low. At these times coal and gas power stations often increase their supply, however flexible electricity loads can help reduce demand, and therefore reduce the grid’s reliance on coal and gas power stations.

Requirements depend on the specific electricity market:

  • The ‘fast reserves’ market requires assets to respond within 1 second of an unplanned grid event occurring, and assets must reduce load or increase generation output for 1 minute. Total interruption time for the year is likely to be less than five minutes.
  • The ‘slow reserves’ market requires assets to respond as close as possible to within 1 second of an unplanned grid event occurring. Interruption time for the year is likely to be less than one hour.
  • ‘Demand response’ markets involving scheduling assets in advance to respond to longer duration events, for example between 5pm and 7pm on a cold winter evening. Events may range from 1 to 4 hours in length, and total interruption time for the year may be 20 - 100 hours.
Assets can be located anywhere in New Zealand.
