High levels of offline generation capacity in the SEM prompts elevated near-term power prices

With approximately 1.3GW of offline capacity at present, supply margins in the SEM are currently tightened by the reduced availability at some of these large thermal plants, supporting elevated near-term power prices of which rose strongly week-on-week.

Outage trends:

  • Offline capacity is forecast to increase substantially from the previous week, up 643MW
  • Unavailable capacity is expected to be at its highest across 1-11 March, remaining at a level 1,268MW during this period
  • Unavailable capacity drops off notably from 12 March, prompted by the return of Huntstown
