With intensifying decarbonization mandates, power generators must navigate the clean energy transition. While converting fully to renewables may not be feasible yet, there are cost-effective strategies to incrementally reduce fossil generation.  

This article explores practical ways for generators to integrate sustainable resources while balancing affordability and reliability.  

Leveraging Hybrid Models  

Phasing in clean energy while still utilizing existing assets through hybrid models spreads costs over time. Examples include: 

• Incorporating battery storage to supplement gas peaker plants. Batteries charge when demand is low and discharge during peaks to avoid firing up gas turbines. 
• Adding solar PV to complement coal or nuclear baseload generation. Solar handles midday loads while baseload assets provide nighttime power. 
• Implementing renewable hydrogen or ammonia co-firing at conventional plants. This displaces a portion of fossil fuels. 
• Retrofitting carbon capture systems to gas plants. Captured CO2 can be stored or utilized. 
• Transitioning coal plants to biomass co-firing. Biomass supplements coal, enabling continued plant operations. 

Hybrid configurations provide flexibility for a gradual transition.  

Repowering with Renewables 

Converting coal sites to solar, wind, geothermal or storage assets repurposes existing infrastructure: 

• Interconnect equipment, transmission lines and land can be reused. 
• Experienced workforces can transition to operating renewables. 

• Permitting and siting is simplified by utilizing the same location. 
• Decommissioning costs are avoided by repowering in place. 

Repowering unlocks savings while progressing sustainability goals. 

Optimizing the Generation Mix 

As legacy assets retire, modeling tools can determine the optimal generation portfolio mix: 

• Factor in projected demand growth, policy incentives, fuel costs, and technology costs. 
• Simulate reliability needs across different weather and operating scenarios. 
• Optimize based on both cost and sustainability metrics. 
• Phase in no-regrets investments while preserving future flexibility. 

An optimized, diversified mix eases the transition strategically. 

Embracing Emerging Technologies 

Cost curves continue to improve for emerging clean energy technologies: 

• Green hydrogen production from electrolysis is declining as scale increases. 
• Small modular nuclear reactors promise safer, cheaper nuclear power. 
• Carbon capture systems are becoming more efficient and affordable. 

• Flow batteries offer long-duration energy storage. 
• Hybrid solar-geothermal plants boost capacity factors. 

New innovations provide optionality as technology evolves. 

Building Workforce Capabilities 

Training programs help workforces transition to new technologies: 

• Upskill plant operators, technicians, and engineers on operating sustainable assets. 
• Foster organizational change management to drive adoption. 
• Hire experts in renewables, storage, and distributed systems. 
• Cultivate partnerships with equipment vendors for training. 

Workforce development unlocks the full value of adopted clean technologies.  

The clean energy transition will take time. But through purposeful strategies, power generators can cost-effectively phase in sustainable resources while ensuring reliability and affordability.
