Cambridge Energy Solutions (CES-US) is a software company with a mission to develop software tools for participants in deregulated electric power markets. CES-US provides information and tools to assist market participants in analyzing the electricity markets on a locational basis, forecast and value transmission congestion, and to understand the fundamental drivers of short- and long-term prices.
Testimony from a DAYZER user:
Dayzer is an efficient production cost model in analyzing the properties of the market system and processes used in clearing and pricing various energy markets. Its distinction is the flexibility it brings to the functional and technical requirements of the base implementation of a transmission topology consistent with the ISO's unified formulations, market algorithms and planning assumptions.
I have utilized Dayzer in various forms (fundamental analysis of congestion, generation and transmission expansion and reliability planning, etc..) however my best experience with the tool is the implementation of Nuclear Asset Rationalization in the energy market, while working for a large utility participating in the PJM market. Dayzer's flexibility (is second to none) in incorporating ISO's market assumptions to calculate the price impact of cycling nuclear units for congestion that leads to significant negative prices at the unit bus. The result of this project led to major changes in the ISO market methodology around nuclear assets. The initial project saved more than $80 Million, and since then saved the market more in congestion cost, reduced FTR underfunding and helped avoid early nuke retirement.
I have used several production cost models in the last decade and I can say Dayzer offers the best prototype environment to simulate the ISO energy market operations.
