Industry: Electric power generation


Transition to renewables brings with it reliability concerns

As efforts to decarbonize gather pace, the utilization of renewable sources of energy has become a matter of urgency, resulting in a global boom in the construction of renewable generation facilities. At the same time, solar and wind energy are yet to fully live up to expectations, due to intermittent output of weather-dependent renewable energy and power grid limitations.

Power producers need solutions that improve reliability of supply

Many power producers are well acquainted with the performance of their generation plant based on the status of their own assets. Determining that it will be difficult to satisfy all portfolio requirements with their existing thermal plants alone, power producers are steadily adding renewable sources to the mix. Power producers also want to maintain and grow their businesses into the future, while increasing the amount of electricity they supply/sell. This requirement has caused power producers to turn to the option of using GTCC+BESS (Gas Turbine Combined Cycle generation combined with Battery Energy Storage System).

Hurdles must be overcome before implementing GTCC+BESS solutions

While GTCC+BESS is seen as the optimum solution for achieving these goals, many hurdles need to be overcome before a GTCC+BESS system is implemented. Below are some examples of the types of questions raised by power plant owners:

  • How much battery capacity do we need to add to our current assets in order to boost and maximize revenue, while ensuring we can provide a stable supply of electricity?
  • It is not known how batteries can best be integrated into GTCC generation in order to optimize operations. In addition, can we manage the battery systems inhouse?
  • What types of battery technology are available? Can these batteries be installed in generation facilities where space is limited?
  • Which provider offers the best solution in terms of reviewing, implementing and operating optimum BESS specifications? Will that provider offer BESS solutions to users of third-party turbines also?
