Plans to improve forecasting of wind farm generation into the national market have been knocked back by the National Electricity Code Administrator's (NECA) Code Change Panel. The panel argues the plans -- proposed by the National Electricity Market Management Company (NEMMCO) -- are insufficiently developed. It says there is a need, in principle, for changes to market rules to deal with the implications of increasing intermittent generation. But it wants NEMMCO to do further work and has suggested it consults the Australian Greenhouse Office (AGO). The AGO is concerned that different forecasting models, which are to be considered as part of the wind forecasting initiative announced by Australia in its White Paper, Securing Australia's Energy Future, last June, will have a bearing on the proposed code changes.
