As Japan’s energy market shifts away from subsidy-anchored structures toward more competitive models such as corporate PPAs and merchant exposure, global sponsors are increasingly expected to manage market volatility, curtailment, and operational uncertainty as part of the investment thesis.
In some jurisdictions including Europe, sponsors and investors are generally comfortable treating these uncertainties as “commercial risks” to be priced into the return model. In Japan, however, domestic lenders prioritize structural clarity and internal explainability—particularly in transactions involving newer asset classes.
This “gap in dialect” is not a problem of sophistication. It is a difference in underwriting philosophy. The challenge, therefore, is not to change this mindset, but to present, allocate, and evidence risk in a manner that resonates with local credit committees without friction, which often arises from misalignments in three areas:
- Risk allocation (“price-in” vs. “explainability”)
- Sponsor role (“asset play” vs. “stewardship”)
- Regulatory and liquidity (Foreign Exchange and Foreign Trade Act timeline mismatch)
In this column, I focus on the first of those, which results from projects under merchant and PPA structures facing risks that cannot always be perfectly transferred to contractors or counterparties.
While sponsors often aim for full pass-through of risks to contractors and OEMs, in practice—particularly in BESS transactions—there can be a real gap between strict performance or availability obligations under an offtake arrangement and the limited scope of OEM warranties and remedies.
Global sponsors may view the residual exposure as an ordinary commercial risk to be priced into the return model. Japanese lenders, however, may treat unallocated or “unexplained” residual risk as a structural weakness—especially if the issue emerges late, when credit approval is already in motion.
Full pass-through is not always required to resolve the misalignment. What is required is explainability and evidence-based management:
- Identify the residual risk precisely (not as a generic “battery risk”)
- Demonstrate how it is technically managed, measurable, and capped (or otherwise constrained)
- Provide evidence that supports the narrative with a combination of data (degradation curves), financial buffers (reserves), and operational protocols; while technical due diligence is a key input, the goal is to prove structural containment
If a risk must remain at the SPC level, ensure it can be logically isolated, quantified, and explained early—before documents harden and timelines compress.
In the next column, I will cover the second common misalignment and how to navigate change of control provisions in Japan.
