Transition Finance Case Studies: Logan and Chambers — Renegotiate, Refinance, Redevelop - RMI

This is one of three coal managed phaseout case studies in the series. The other two are ACEN — Project Sale to Special Purpose Vehicle and Tocopilla Units 14 and 15 — Results-Based Loan Incentive.

The global power sector’s transition from “coal to clean” will be critical to meeting urgent climate targets but must be managed carefully to ensure the transition supports economic development. For a just coal-to-clean transition, existing coal assets must retire earlier than originally planned. This managed coal phaseout requires strategic financing to execute, which can be further complicated by tight balance sheets, a high cost of capital, and coal’s near-complete insulation from competition. Despite such barriers, financial institutions (FIs) are stepping in to make just coal-to-clean transactions happen.

Carefully constructed financial tools called coal transition mechanisms (CTMs) can help generators, electricity customers, and the public overcome these complications and realize the benefits of cheaper clean energy. In the past few years, the first wave of FIs has begun to capitalize on the opportunity to enable early coal plant retirement through the use of CTMs in various markets globally. The continued deployment of CTMs to accelerate the energy transition is especially critical in emerging markets and developing economies (EMDEs), as a significant amount of financing will be needed to enable a managed and just coal transition. Although we have seen billions of dollars committed to coal transition globally, most of that finance has not yet been deployed (and not at scale).

With these case studies, RMI highlights lessons learned from the first few successful transactions and the enabling factors they relied on to promote increased awareness and use of such factors for managed phaseout transactions moving forward. Specifically, we have showcased managed phaseout transactions that enabled the early retirement of coal plants:

These case studies demonstrate innovative and potentially replicable approaches to utilizing CTMs that could apply in diverse geographies and market structures, most notably in emerging and developing economies.[1]

These case studies highlight the key factors that enabled early retirement as examples so that others can carry over these learnings and contextualize them for new markets and future transactions. Across all these case studies, we identified the following enabling factor themes:

[1] The material for the case studies was compiled from a combination of qualitative research using information in the public domain and interviews with stakeholders that financed, designed, or assisted in these transactions.

Reducing emissions from the power sector is key to meeting climate targets — in 2021, the power sector accounted for nearly 44% of global CO2 emissions. As global access to electricity expands and countries turn to electrification as a means of decarbonization, the need for a rapid power sector transition becomes more imperative.

Core to this challenge is the transition away from coal-fired power, which accounted for 73% of the sector’s greenhouse gas emissions in 2021. Utilities and independent power producers (IPPs) worldwide are wrestling with the coal-to-clean transition, especially how to enable the managed phaseout of coal assets. This managed phaseout of coal is complicated by long-term contracts to purchase electricity from coal plants, utility incentives and regulation, the role of coal in supporting national economies and local livelihoods, and other factors. Given these hurdles, well-designed financial structures called coal transition mechanisms (CTMs) can help generators transition away from coal and unlock the benefits of cheaper, cleaner renewable energy sources.

Over the past few years, the first wave of financial institutions (FIs) has begun to capitalize on the opportunity to enable early coal plant retirement using innovative financial mechanisms in markets like Chile, the United States, and the Philippines. As early-stage pilots, each of these mechanisms were designed to meet the needs of specific market and grid conditions.

To scale coal managed phaseout from these first few pilots to the hundreds of gigawatts (GW) needed to meet climate targets, these transactions must become less risky, more replicable, and better able to attract private finance. These case studies highlight the key factors that enabled successful early coal retirement projects. The intention is that key stakeholders in the energy transition (FIs, national and sub-national governments, utilities and IPPs, etc.) can adapt and apply these lessons to create an enabling environment in new markets, mobilize increased private FI participation, and rapidly scale these types of transactions. Below, please find our case study Logan and Chambers — Renegotiate, Refinance, Redevelop. Other coal-to-clean case studies can be found here.

In 2022, private equity firm Starwood Energy Group (now Lotus Infrastructure), the majority owner of the Logan (225 MW) and Chambers (285 MW) coal portfolio, accelerated the retirement date of the plants by 30 months, from 2024 to 2022. Starwood did this by renegotiating the Power Purchase Agreements (PPAs), refinancing project-level bonds, and agreeing to redevelop the sites into clean energy resources.

The portfolio’s output had originally been sold primarily to Atlantic City Electric (ACE) via 30-year PPAs signed in 1994. ACE had agreed to terminate the PPAs in 2022 instead of 2024 — 30 months early — thereby saving ACE customers around $30 million.[1] ACE would originally have paid Starwood $258.5 million (net) from 2022 to 2024; under the renegotiated PPA, ACE would only pay Starwood $228.5 million (net). Against these $228.5 million revenues, Starwood refinanced using $200 million in debt from MetLife in part to help pay ACE for the early PPA termination. The plants ceased operations in June 2022. It took Starwood 12 months to work with all counterparties to negotiate the agreement. The early decommissioning was expected to result in the reduction of 3.9 million tons of CO2. Starwood plans to redevelop the sites at both Logan and Chambers into grid-scale batteries, at 876 MWh and 960 MWh in size respectively. Additional details on the Logan and Chambers coal units can be found in Appendix Exhibit 2.1.

The transaction has three key elements, which interact with and reinforce each other: 1) Renegotiated PPAs allowed for early coal retirement, which enabled Starwood to 2) refinance from institutional investors as an attractive investment opportunity, which then enabled Starwood to 3) utilize the site and its favorable interconnection grid position to develop battery storage.

The above pilot along with others that can be found here have laid the blueprint for how well-designed, specific financial mechanisms can help accelerate the coal-to-clean transaction and unlock the benefits of clean energy. However, scaling from a few pilots to the effort required to meet ambitious climate targets requires more easily replicable models for early coal asset retirement. These case studies highlight lessons learned from past transactions and the enabling factors they relied on to promote increased awareness and use of such factors for managed phaseout transactions moving forward. Across all highlighted case studies, we identified the following enabling factor themes:

By analyzing the carefully constructed financing mechanisms that enabled these pilots, we have identified replicable formats that can serve future transactions in diverse geographies with coal capacity that can be retired. Given the speed with which such transactions must scale, it is crucial to continue iterating on and sharing best practices of innovative managed phaseout.
