A new preliminary report conducted by GE Energy Consulting and released by PJM Interconnection calculated the amount of new transmission lines needed under "several scenarios for additions of wind and solar generation to the PJM grid," which provides wholesale electricity in all or parts of 13 states, including Ohio, Midwest Energy News reports. Details will not be available until the report is finalized, but the overall impacts were recently highlighted in a presentation to stakeholders and include "lower emissions of pollutants and greenhouse gases; no power outages and minimal curtailment of renewable energy; lower systemwide energy production costs; and lower wholesale customer power costs with the additional wind and solar resources." Of particular significance is the report's assumption that "onshore wind farms servicing PJM" would run for a larger percentage of time than critics say is possible. By assuming that wind farms run between 14 and 18 percent of the time, the report counters the rhetoric that "enormous amounts of backup generation [are needed] to support a high level of renewable power," the article said. For more, read the full story and access the presentation to stakeholders on the PJM Renewable Integration Study (PRIS).
