A firm energy market for Colombia is presented. Firm energy—the ability to provideenergy in a dry period—is the product needed for reliability in Colombia’s hydrodominatedelectricity market. The firm energy market coordinates investment in newresources to assure that sufficient firm energy...

We present a simulation analysis of the proposed Colombian firm energy market. The mainpurpose of the simulation is to assess the risk to suppliers of participation in the market. We alsoare able to consider variations in the market design, and assess the impact of alternative...

Wholesale electricity markets are commonly organized around a spot energy market.Buyers and suppliers submit bids and offers for each hour and the market is cleared atthe price that balances supply and demand. Buyers with bids above the clearing pricepay that price, and suppliers with offers...

We argue that a capacity market is needed in most restructured electricitymarkets, and present a design that avoids problems found in the early capacitymarkets. The proposed market only rewards capacity that contributes toreliability as demonstrated by its performance during hours in which there...

A forward reliability market is presented. The market coordinates new entry through the forward procurement of reliability options—physical capacity bundled with a financial option to supply energy above a strike price. The market assures adequate generating resources and prices capacity from...

Wholesale electricity markets are commonly organized around a spot energy market. Buyers and suppliers submit bids and offers for each hour and the market is cleared at the price that balances supply and demand. Buyers with bids above the clearing price pay that price, and suppliers with offers...

We argue that a capacity market is needed in most restructured electricity markets, and present a design that avoids the many problems found in the early capacity markets. The proposed locational capacity market pays suppliers based on their demonstrated ability to supply energy or reserves in...

A firm energy market for Colombia is presented. Firm energy—the ability to provide energy in a dry period—is the product needed for reliability in Colombia’s hydro-dominated electricity market. The firm energy market coordinates investment in new resources to assure that sufficient firm...

This paper compares market designs intended to solve the resource adequacy (RA) problem, and finds that, in spite of rivalrous claims, the most advanced designs have nearly converged. The original dichotomy between approaches based on long-term energy contracts and those based on short-term...
