Energy transition: Unlock incremental value from retiring coal plants

Coal generation plant retirements are accelerating

Cost pressure is mounting

Under mounting cost pressure, plant operators need to better understand and quantify three categories of risk—market, regulatory, and investor—each of which has the potential to push coal “out of the money” and drastically accelerate the pace of closure. Variables influencing this are:

• Deflated power market pricing resulting from an influx of cheap gas, rapid buildout of renewables with low-to-no marginal cost, plus dampened electricity demand.
• New hurdles driven by stringent emission controls, state renewable policies, and changing power market rules (e.g., potential repeal of FERC’s Minimum Offer Price Rule)
• Less attractive financing options given emerging focus on environmental, social and governance (ESG) factors, and a renewed willingness to securitize debt in order to accelerate closure (e.g., ratepayer-backed, anticipated renewable portfolio revenues).

Our analysis

Our analysis suggests power market pricing heavily influences operator decisions to expedite plant shutdowns—starting with the least efficient units as defined by O&M cost and heat rate. We found that from the time of announcement to approximately 5 years prior to closure, retiring baseload coal plants’ median O&M cost per MWh is 25% higher than that of the operating fleet².

Examining market risk in isolation, up to 50% of PJM large coal (>500 MW) capacity is expected to retire by the end of 2035 if market capacity prices follow the same linear trajectory as 2018-2022 auction prices³. A 25% step reduction of the forecasted capacity price curve, however, could lead to a near doubling of closures.

Operators should recognize the long 8-10 year planning cycle and adopt a meaningful “run to retire” strategy—one that unlocks incremental value by optimizing the organization and supply chain, managing assets for recovery, and honing planned capital expenditures, while retraining and transitioning the workforce.

Cost savings delivered

Experience tells us operators can achieve meaningful cost savings (potentially in the millions of dollars) in three cost categories:

• >25% in annual non-fuel O&M
• >5% in fuel O&M
• 40-50% of typical maintenance capital expenditure

Adopt a "run to retire" strategy

To achieve these incremental savings, coal operators should adopt a "run to retire" strategy, ideally 8-10 years before closure, that:

• Evaluates, and ultimately secures, asset transition and financing options over the planned shutdown period.
• Establishes a short- and long-term roadmap that defines the implementation strategies for budget/investments, organizational change, asset management risks, workforce transition plans, supply chain, and third-party contract modification. It sets out an end state vision for the property and reduces shared service costs.
• Includes a phased stakeholder change management and communications plan, for internal as well as external audiences.
• Develops an internal governance committee of executives and experts, how often they will meet, and how they will make decisions, including assessing (and correcting) the plan as needed.

Market, regulatory, and investor forces are squeezing coal generation profitability. And units with the highest operating costs are most at risk of being pushed "out of the money." Operators have a unique opportunity to unlock incremental value by adopting a "run to retire" plan that focuses on optimizing the organization, workforce, assets, and planned capital projects, while at the same time transitioning to a renewable generation portfolio.
