Mamonal 100 MW Power Station

Latin America and the Caribbean

October 22, 2020

K&M served as project developer, technical consultant and owner’s engineer for the 100 MW Mamonal project. As such, K&M’s involvement in Latin America’s first-ever privately financed non-recourse Independent Power Project (IPP) encompassed a broad range of advisory services. K&M developed this pioneering project on a Build-Own-Operate-Transfer (BOOT) basis and structured the transaction to achieve financial close within a period of only 7 months. K&M worked with the government to develop and reorganize the commercial, regulatory, legal and securities framework to allow for private investment. The Mamonal plant sells electricity to both private industries and the national grid, thus the project structure required negotiation of a full range of issues related to market-oriented operation in the energy sector, including wholesale and retail tariff models and methodologies, fuel supply transportation and pricing, and spot market system.
K&M developed risk mitigation arrangements, which included the implementation agreements, long-term lease agreement, and the sales agreements to private and public clients. K&M worked with the various government entities and local partners involved to negotiate the complete terms of the transaction including: fair tariff wheeling arrangements (the first in Colombia); EPC construction contract which included procurement procedures; Power Purchase Agreement (PPA); Security Package agreements; and non-recourse financial agreements.
Mamonal’s success was covered extensively in the trade media. It was recognized as “Deal of the Year” in 1994 by Project Finance International Yearbook and “One of the Ten Most Creative Deals” of 1993 by Infrastructure Finance. The contractual guarantees, risk allocation concepts and the incentive structure of the Mamonal transaction, as conceived and negotiated by K&M, are now being used as a model worldwide. The $100 million facility consists of a 100 MW (ISO) natural gas-fired combined cycle power plant in a steam-augmented mode. The power island includes two General Electric LM 5000 steam injected gas turbines (STIG) and two heat recovery boilers (HRSG). It connects to the grid through a 69 kV switchyard and 1 km 69 kV transmission line. Status: Commercial operation 1994.
