• The Federal Energy Regulatory Commission has adopted a rule requiring transmission systems to adopt 15-minute scheduling to help providers of renewable energy avoid "excessive imbalance service charges because they cannot adjust their service schedules within each operating hour."
• In addition, customers who have variable resources are now required to give transmission providers "provide meteorological and operational data to transmission providers engaging in power production forecasting" because, as FERC put it in a news release, " forecasts are only as good as the data on which they rely."
• At the same time, FERC proposed making a rule that would accept National Energy Reliability Corp. revisions in defining the core system to include "all transmission, real power and reactive power facilities operated or connected at 100 kilovolts or higher."

From the article: "The Federal Energy Regulatory Commission has approved a rule aimed at improving the integration of variable energy resources, such as wind and solar power, into the transmission system. The June 21 action, which finalized a lengthy rulemaking process, will promote more efficient operation of the system as integration of variable resources increases, the agency said. ..."
