As communities look for reliable, flexible sources of power, concerns about noise from new energy projects often come first. Today, we share how modern reciprocating internal combustion engine (RICE) power plants are specifically engineered to provide significant electricity output while maintaining peace and quiet in surrounding neighborhoods.
A Case Study: 214 MW Liberty Station Project, Casey County, Kentucky
East Kentucky Power Cooperative (EKPC) has designed a 214 MW RICE facility on a 100-acre site in Casey County, Kentucky. Detailed design and modeling work show how such a plant can fit within a modest footprint while keeping sound levels extremely low at the property line.
Noise Impact: How Quiet is Quiet?
Independent acoustic studies modeled the plant operating at 100% load:
- At the facility center: Noise levels reach 60–65 dBA (similar to a dishwasher in the next room).
- At the property boundary: Levels drop to about 55 dBA, just above the quiet hum of an office environment.
- Beyond the boundary: Noise diminishes to 40–45 dBA, comparable to a quiet residential neighborhood or a farm field with birdcalls.
For context, a passing diesel truck at 50 feet measures 80 dBA, while a jet flyover can exceed 100 dBA. The RICE facility operates far below these thresholds.
Proven Design for Noise Reduction
The Liberty Station project highlights standard industry measures used to reduce sound:
- Engine Hall Enclosure: All 12 Wärtsilä W18V50DF engines are fully enclosed in an acoustically treated building.
- Exhaust Silencers: Advanced silencers on each stack minimize high-frequency sound.
- Quiet Cooling Systems: Radiators equipped with low-noise, variable-speed fans further reduce operating noise.
- Site Layout: The 100-acre site provides natural buffering and distance between the plant and neighboring homes.
Why RICE Topology Matters for BTM Buyers
This design illustrates the same principle that runs through Smartland Energy's modular RICE architecture: a 214 MW site built as a set of 12 reciprocating engines delivers native N+2 redundancy, supports rolling maintenance without site outages, and operates quietly enough to be a good neighbor. The same topology that makes Liberty Station community-compatible is what makes Smartland's modular RICE units the right fit for data center, industrial, and defense buyers facing community-acceptance and permitting timelines as part of their procurement reality.
Moving Forward
Reliable, flexible, and quiet power generation designed with communities in mind isn't aspirational - it's the technology Smartland Energy uses for the buyers we serve.
