Strategic implications
Gresham House / SUSI Partners' edge lies in its ability to de-risk complex energy infrastructure projects in emerging markets, a niche where passive capital struggles. The main risk is over-reliance on the pace of the global energy transition; policy shifts in key markets like Southeast Asia could disrupt deployment. A signal to change the read would be a pivot away from active de-risking or a reduction in emerging market focus, indicating a shift to more mature, lower-risk markets.
Where they could go further
The firm could enhance its strategy by establishing a dedicated fund for early-stage renewable technology startups, capturing value earlier in the innovation cycle. Expanding active value creation services to include digital transformation for traditional energy assets could open new opportunities in the transition. Developing a standardized de-risking framework for emerging markets would improve scalability and reduce operational overhead across deals.
