Texas Will Survive Luminant’s Closing of 2 Coal Plants

• 1,860 MW Monticello, • 1,195 MW Big Brown, Luminant -Retirement Plan


“A new study says the Texas electric grid would still be reliable if two of the state’s coal plants shut down in the coming years.

The study comes from a progressive advocacy group that calls some coal plants “old, inefficient and dirty.” Consulting firm Electric Power Engineers performed the study for the group Public Citizen. It looked at what would happen if Dallas company Luminant closed its Big Brown and Monticello plants by the year 2021.” – Travis Bubenik  (Source: Houston Public Media)

Thought Leadership at TREIA GridNEXT

Electric Power Engineers, Inc. Hugo Mena discusses the benefits of Energy Storage

“Once you add solar to storage, then you essentially have a microgrid that can sustain an hour or so of outages,” said Hugo Mena, Electric Power Engineers’ vice president of business development. “EPE has seen this coming for a couple of years because of the integration of storage, whether to a solar plant or a wind farm or storage as a transmission asset, is positive for the grid. The question now is, when is it going to be economically feasible for developers or utilities to implement this technology in their systems? We’ve seen at the municipal level that it’s become economically feasible, but some [investor-owned utilities] are also installing storage for microgrid purposes.”  (Source: RTO Insider)

Energy Market Analysis

At Electric Power Engineers, we understand the grid and can integrate your needs and projects into the modern grid. Since 1968 we have been power engineers for transmission & distribution utilities and generation resources.

Optimization with Cost and Congestion Management

Transmission congestion can have a significant impact on the energy market and affect revenue potential. Many markets use locational marginal pricing (LMP) to determine system congestion, curtailment, and negative pricing. LMP provides a mechanism for wholesale electric prices to reflect the value of the power at different locations while accounting for patterns of load, generation capacity, and physical limits of the transmission system.

EPE has extensive experience in performing LMP studies using customizable computer models to calculate prices at specific locations and market hubs. We use our experience with transmission and distribution planning and system studies to design and implement electrical grids that reflect the current and future needs of our clients.
