Solar grazing cost analysis: Sheep vs. mechanical mowing
Key Finding
Documented 75% cost savings using solar grazing versus traditional mechanical mowing.
Overview
Tampa Electric / Paul Davis present compelling evidence for maintenance cost reduction through regenerative practices. This 2020 study demonstrates how alternative vegetation management approaches can significantly reduce O&M expenses while improving environmental outcomes.
Methodology
The study compared traditional mechanical maintenance approaches with regenerative alternatives, tracking costs, labor requirements, and operational metrics across multiple installations over extended periods.
Relevance to TerraNext
TerraNext's regenerative management philosophy aligns directly with these findings. Documented 75% cost savings using solar grazing versus traditional mechanical mowing. Our approach incorporates directed grazing and native vegetation establishment to achieve similar cost reductions while building soil health and biodiversity.
Key Implications
- Maintenance costs can be reduced by 30-75% depending on approach
- Reduced mechanical intervention preserves soil structure and biology
- Lower cleaning frequency needed when dust generation is controlled at source
- Initial investment in regenerative transition typically pays back within 2-3 years
Why This Research Matters
Direct industry evidence for maintenance cost reduction
Provides benchmark for solar grazing economics
Validates regenerative approach for utility-scale operations
