The article presents several ways in which dispersed solar power generating systems can help to prevent major outage. Experts estimate the total regional cost of the August 14, 2003, Northeast outage at upward of $8 billion. This article discusses how dispersed photovoltaic (PV) generation can increase energy security by preventing, and hastening recovery from, this type of outage. On the afternoon of August 14, loads throughout the U.S. Northeast, though not at record levels, were high, driven by air conditioning demand. The region was experiencing large power transfers from the South Central states to the North. Much of that power transited through Ohio on its way to the major load centers of Detroit, Cleveland and Toronto. Not only could a dispersed PV resource lower the probability of massive grid failure by injecting power at peak demand times, but it could also provide insurance against outages should they nevertheless occur. Properly designed customer-sited PV installations that include emergency storage/backup at a modest additional cost could provide enough emergency power to keep critical loads at businesses and residences going almost indefinitely during an outage. The outage-preventive attributes of PV may even be enhanced when systems are designed with outage recovery in mind, by making part of the storage/backup reserve available to grid operators for emergency load management. |
