What is PGC 5.0 with CTES?

PGC 5.0 with CTES + MPC systems generate cooling during efficient hours, store the cool energy in phase changing materials which are kept in large insulated customised tanks. These large tanks can also be buried underground which saves space and effective utilization of land. By doing optimised demand management, the energy consumed for producing cool energy is reduced. The produced cool energy is stored for effective usage as per the requirement which saves good amount of air conditioning cost. The system also uses chillers to produce cooling at night and discharge it during the day, helping to do demand management while maintaining the required indoor comfort. This approach also improves overall system efficiency by allowing chillers to operate under optimal conditions and supports demand-side management of air conditioning. This methodology helps significantly to reduce peak electrical load compared to conventional systems, while still delivering consistent cooling performance.The stored cooling energy is discharged during demand to reduce air conditioning cost and optionally MPC – Model Predictive Control can be integrated to achieve higher air conditioning cost.

Operational Flow of PGC 5.0 with CTES

Generation

Cooling is produced during off-peak hours when electricity demand and tariffs are lower for efficient operation.

Storing

The cooling generated during off-peak hours is stored within the CTES system for later operational use.

Usage

The stored cooling energy is discharged during peak hours to meet demand and reduce electrical load.

Technical Benefits of PGC 5.0 + CTES

Reduced Equipment Sizing and Capital Requirements

PGC 5.0 with CTES + MPC systems enable significant reductions in chiller plant sizing by meeting peak cooling demand through a combination of optimised chillers and stored energy instead of oversizing equipment. This results in more efficient system design and avoids the need for oversized chillers for maximum demand and buffer.

  • Completely eliminates big sized generator for operating entire Air Conditioning system since we have storage tanks
  • Small generator maybe sufficient to run the pumps and blowers if needed
  • Requires only 40%–70% of refrigeration capacity compared to conventional systems
  • Enables optimised chiller plant sizing through use of stored cooling energy
  • Reduces capital cost due to optimised equipment and auxiliaries
  • Lowers maintenance needs for fans, pumps, and supporting components

Enhanced Chiller Efficiency Through Optimal Operation

PGC 5.0 with CTES + MPC systems enable chillers to operate under their most efficient conditions, contributing additional energy savings compared to conventional systems. Instead of running inefficiently at partial loads, chillers operate at full-load for shorter periods while charging storage, which improves operational efficiency and reduces unnecessary cycling. Operating during nighttime hours also improves heat rejection due to lower ambient temperatures, further enhancing overall system performance.

  • Delivers an additional 7%–15% energy savings through improved chiller operation
  • Enables chillers to run at full-load conditions for higher efficiency
  • Eliminates inefficient cycling associated with part-load operation
  • Improves heat rejection due to cooler nighttime ambient temperatures
  • Enhances coefficient of performance (COP) and reduces overall kWh consumption

Efficient Demand Management

The most significant contributor to air conditioning power savings in PGC 5.0 with CTES + MPC systems comes from Demand Management. The system produces and stores cooling during off-peak periods (typically night time) when electricity demand and tariffs are lower in few countries like India (Peak hours power tariffs are 20 – 40% higher than the normal power tariffs), and discharges the stored cooling during peak demand hours. This approach helps reduce peak electrical demand while maintaining effective cooling performance because of effective and efficient storage systems.

  • Reduces electricity demand by 30–40% during peak hours
  • Shifts 35%–50% of total cooling load to off-peak hours
  • Uses chillers to cool water or make ice during low-tariff periods, Utilises stored cooling during high-demand hours
  • Achieves 30%–45% peak demand reduction compared to conventional systems

Real-World Performance Data

Field studies and analysis demonstrate that the performance benefits of PGC 5.0 with CTES + MPC systems are achievable in real applications. This indicates meaningful reductions in electricity consumption, HVAC electrical load, and carbon footprint across commercial implementations.

  • Can reduce overall electricity consumption by around 20%
  • Commercial implementations reduce HVAC electrical load upto approximately 41%
  • CTES + MPC systems can achieve up to 25% peak power reduction
  • Advanced PCM-CTES systems demonstrate up to 40% electricity savings in optimised chiller systems, Supports carbon footprint reduction while maintaining thermal comfort

System Integration and Optimisation Benefits

Efficient PGC 5.0 with CTES + MPC systems incorporate advanced control strategies that optimise performance across multiple operating parameters. Advanced systems using Phase Change Material (PCM) technology provide higher energy-carrying capacity than water, resulting in improved efficiency and space savings. Optimised system operation can also deliver measurable annual cost benefits.

  • Uses advanced control strategies to optimise system performance
  • PCM technology offers higher energy storage capacity than water
  • Enables greater efficiency and space savings
  • Can achieve annual cost savings of up to 10% through optimisation

Off-Peak Energy Rate Advantages (in some countries)

The use of off-peak electricity rates provides substantial cost savings and contributes to effective power reduction. PGC 5.0 with CTES + MPC systems take advantage of lower electricity prices at night through load shifting, reducing overall operational costs and helping facilities avoid expensive peak demand charges that form a significant portion of electricity bills.

  • Off-peak electricity rates can be 20–40% cheaper than peak rates
  • Some utilities offer 20–30% lower energy prices during nighttime hours
  • Enables use of lower-cost electricity through effective load shifting
  • Helps avoid peak demand charges, reducing total electricity bills
