日本語

インドの州レベル電力調達を対象に、配電会社（DISCOM）の財務困窮が脱炭素化に与える影響を分析。短期的には財務逼迫がむしろ再エネ調達を相対的に増やし、石炭調達を減らすことを発見。must-run規制が再エネを保護する一方、流動性制約に敏感な石炭が削減されるためである。長期的には再エネ入札や送電網拡張への影響は弱く、電力会社破綻が転換の制約になるという通説を限定づける。

English

Using original data on Indian state-level electricity procurement, this study examines how distribution utility (DISCOM) financial distress affects decarbonization. Counterintuitively, short-run distress is associated with more renewable and less fossil procurement, as liquidity-constrained DISCOMs cut coal while must-run rules protect renewables. Long-run effects on renewable tendering and transmission expansion are weak, qualifying the view that utility insolvency binds the energy transition.

📝 gxceed 編集解説 — Why this matters

日本のGX文脈において

日本の電力小売・配電事業の財務健全性と再エネ調達の関係を考える上で示唆的。地域独占電力の財務制約が脱炭素の速度と構成に与える影響は、日本でも今後の論点になり得る。

In the global GX context

Adds empirical nuance to the global debate on whether utility financial health constrains the energy transition, relevant to emerging-market decarbonization and to how must-run and dispatch rules interact with financial stress.

📄 Abstract（原文）

How do financial constraints shape the energy transition in developing countries? I study this question in India, where electricity procurement is governed at the subnational level. Electoral politics motivates state governments to subsidize electricity consumption, resulting in financial stress for electricity distribution utilities (DISCOMs). Using multiple sources of original data on utility and plant operations, I investigate the relationship between financial distress and decarbonization. I theorize that the effect of utility insolvency depends on the margin considered—dispatch vs. capacity investment—and on institutions. Counterintuitively, but consistent with my theory, I find that financial stress is associated in the short run with greater relative procurement of renewable energy and less procurement of fossil fuels. Mechanism tests suggest that coal dispatch is more sensitive to liquidity constraints, as distressed DISCOMs cut back on coal deliveries while renewable energy remains protected by “must-run” dispatch regulations. In contrast, I find at most weak evidence that insolvency raises challenges for decarbonizing electricity in the long run: insolvency shows no relationship with renewable-energy tendering, only suggestive evidence that it slows renewable capacity investment, and similarly weak evidence that it curtails expansion of transmission lines that renewables need to scale. The results qualify the conventional wisdom that electricity utilityinsolvency is a binding constraint on the energy transition.
