Volatile generation causes blackouts.
India’s move to stabilize its power grid by asking wind farms to accurately predict their output a day in advance or face fines will deepen the slowdown in Asia’s second-biggest wind market, Tata Power Co. (TPWR) said.
A directive took effect this week ordering wind farms with a capacity of 10 megawatts or more to forecast their generation in 15-minute blocks for the following day. Missing estimates by more than 30 percent will incur penalties.
“Forecasting at 15-minute intervals is very challenging,” and could cost a 100-megawatt farm an estimated 250 million rupees ($4.2 million) a year, Tata Power said in an e-mailed response to questions. “Developers will see this as a further handicap” and penalties will “jeopardize” the industry’s growth, the nation’s second-biggest developer said.
