Column: More wind power needs better forecasting: Gerard Wynn

Read the full story from Reuters.

One way to cut the cost of greater reliance on wind power is to improve day-ahead weather forecasting, to make it less expensive for grid operators to balance national demand and supply.

As countries seek to meet renewable energy targets, extra costs include subsidies, direct grid connection, backup reserves to cover intermittency and short-term grid balancing.

Short-term balancing adds costs both for grid operators, which have to pay power plants to turn off or to meet excess demand, and for generators switching on and off units designed for constant, baseload operation.
