As Midwest market share for wind rises, gas generation sees downside risk

摘要

Recent wind capacity additions in the US Midwest and higher utilization factors for the renewable are giving wind generation more market share in SPP and MISO this month, compared to last November, in a trend that could pose downside risk to regional gas-fired power burn this winter. Month-to-date, wind has captured over 41% of the market share for power generation in SPP, up from an average 31% market share month-to-date last November. In MISO, wind power has accounted for 20% of the generation share this month compared to just 11% last November, data from S&P Global Platts shows. Higher market share for wind this month can be attributed in part to increased capacity. The combined territories for SPP and MISO are now home to over 48 GW of nameplate wind-generating capacity – up from an estimated 42.6 GW of capacity last November.
