Coal remains competitive for power generation in the central United States

During the first four months of 2026, coal-fired power generation in the Midcontinent Independent System Operator (MISO) region maintained a strong competitive edge over natural gas. Data from Hellenic Shipping News indicates that the dark spread remains favorable, ensuring sustained demand for bulk carriers transporting thermal coal across inland waterways and coastal routes. Vessels such as the MV Iron Duke and MV Coal Transporter continue to play a vital role in maintaining the energy supply chain for these central United States power plants.

The continued reliance on coal-fired generation necessitates strict adherence to MARPOL Annex VI regulations regarding sulfur oxide emissions and particulate matter control. Compliance departments must ensure that vessels operating in these regions maintain rigorous bunker delivery note records and engine logbooks to satisfy Port State Control inspections. Furthermore, adherence to SOLAS Chapter II-1 requirements for machinery and electrical installations is critical, as older bulk carriers must balance operational efficiency with the stringent environmental standards enforced by the International Maritime Organization to avoid costly detentions.

Chief engineers and second engineers must prioritize the maintenance of emission abatement systems and fuel monitoring equipment to ensure peak operational efficiency. These officers should focus on optimizing fuel consumption patterns to align with the favorable dark spread economics. It is essential for engine room teams to stay updated on regional emission control area requirements and maintain precise documentation to facilitate seamless inspections at major coal-handling ports throughout the central United States.
