RT Journal Article SR Electronic T1 Merchant Power Plants JF The Journal of Structured Finance FD Institutional Investor Journals SP 27 OP 42 DO 10.3905/jsf.1999.320178 VO 5 IS 1 A1 Peter N. Rigby YR 1999 UL https://pm-research.com/content/5/1/27.abstract AB Two years ago, Standard & Poor's published its first criteria for rating proposed project financing of merchant power plants (MPP). To further facilitate the development and project financing of MPPs, the agency recently has revised those criteria. Because the forces affecting market share are the essence of business risk in power generation, the criteria emphasize competitive analysis. As sponsors develop mechanisms to unbundled the risk introduced by competition, stronger MPPs can - as some have - reach investment-grade or near investment-grade ratings. However, the fact that only a few projects have attained investment-grade ratings indicate just how challenging and risky MPP project financing may turn out to be.
