Ann: Infigen Monthly Production - March 2019, page-4

Look at the overall production YoY to see the average as the wind production is seasonal. IFN production excluding Bodangora is up 6% on last year to date.
Productivity is not really a measure with wind as the output is reliant on the spot market demand, contracted supply deals, loss factors in the network, and LGC prices.
The improvements come from capital management gains, overhead management, selling more product to contracted customers by increasing firm capacity such as comes from battery storage and on-selling other production through IFN control infrastructure.
With more energy source the variability goes down as well as shown with the graph this year compared to last. Thisis because the wind variability is regional as well as seasonal and the averaging effect of many locations reduces that.
Predictability is good because that reduces risk of penalties for C&I contract shortfall and allows more capacity to be earmarked for contracts and less selling into the less profitable spot market.
