    SummaryIntroductionFuel CostsCash CostsOperating CostsWhy Does This Matter? Tracking Least Cost and Climate DisclosureConclusion1. The operating costs of coal units are complex and depend on many variables. Coal units are complex, long-life assets. The costs associated with operating coal units depend on location, unit type, unit size, environmental regulation and owner strategies. 2. Fixed costs combined with lower running hours are devastating for coal power economics. The capital and fixed operations and maintenance (FOM) costs associated with keeping units online or compliant with environmental regulation can onl...
  • Power plant OM: how does the industry stack up on cost?

    Gas TurbineLarge-Scale Solar PhotovoltaicSubcritical Coal PowerOnshore Wind PowerLarge-Scale HydropowerNuclear PowerGas-fired power generation is known for having relatively low OM costs when compared to other generation methods, and the IEA’s stats bear this out. Power plants equipped with simple-cycle combustion turbines, the most common – and least efficient – gas-fired technology, have reached an average annual OM cost of just $20 per kilowatt (kW) produced, making this technology the cheapest OM option in the industry.According t在power-technology上查看更多信息
