The energy transition – and the growth of renewable power generation – is fundamentally changing the operating environment for power plants. Power generators are challenged by strengthening environmental regulations, fluctuating fuel prices, labor attrition and supply chain disruption. On top of these factors, load demand variations due to renewable generation can cause plant reliability and performance to suffer. Though it may not have been designed for it, your plant needs to operate flexibly – and legacy methods for managing plant performance are no longer enough.

In power plants designed for high steady-state generation, variable operation can cause equipment degradation and negatively affect power plant heat rate. Plant teams need accurate, easy to access data and insights to know where the problem is occurring and how much it is costing. The ultimate goal is ambitious, but necessary — improving both efficiency and reliability, while reducing emissions and supporting increased renewable power implementation for the future.

In conversation with POWER Magazine, GE Digital experts discuss methods to reduce or eliminate the impacts of flexible generation, including software designed to both monitor performance and provide proactive, actionable recommendations for Operations & Maintenance.
