Summary

In this episode of Transmission, Ed Porter from Modo Energy interviews Conrad Purcell, an infrastructure and energy projects partner at Haynes Boone, about financing battery storage projects. They discuss two primary funding routes: bank project finance and joint ventures with institutional investors. Project finance involves lending based on future contracted revenues, with banks focusing on certainty and risk mitigation. For battery storage, this often results in shorter loan terms (mini perms) due to technology risks and revenue uncertainty. Joint ventures, on the other hand, involve institutional investors providing capital in exchange for a share of revenues, often with more flexibility and patience. The conversation covers the key factors that make a battery project bankable, including grid connection delays, lender expectations on warranties and EPC structures, and the shift towards merchant-heavy revenue stacks. They also explore the end-to-end development process from early development to financial close. The episode provides practical insights for developers, financiers, and analysts in the energy storage market.
