Excess Capacity and the Economics of Hydro-Québec Purchase

Vermont Public Service Department
Completed September 1998

Synapse provided direct testimonies before the Vermont Public Service Board regarding the economics of the Hydro-Québec purchase by Central Vermont Public Service Company and Green Mountain Power Company (GMP).  Synapse’s analysis found that the purchase represented excess capacity in both cases and recommended that these excess costs be shared between ratepayers and stockholders.  In the GMP case, the Board found in favor of Synapse’s used-and-useful recommendation, and required a sharing of the above-market costs of the purchase.  Testimonies filed in February 1998 and September 1998.
