Transforming Wastewater Management with Battery Storage
Battery Storage Systems (BESS) are emerging as a financially prudent alternative to diesel generators in municipal wastewater facilities. A recent project in New York State illustrates this shift, where a Viridi battery system replaced a diesel backup generator, showcasing a significant reduction in operational costs.
Cost Analysis: What This Project Costs
The total installed cost for the Viridi BESS was $130,000. However, federal incentives under the Clean Energy Investment Tax Credit (ITC) substantially lower this figure. Municipalities can access a 40% total ITC, translating to a net capital cost of just $78,000 after incentives.
Who Wins? Municipalities and Taxpayers
Municipalities stand to gain from this transition. By utilizing a BESS, they can expect to save between $18,000 and $35,000 annually. This includes reductions in operating and maintenance costs associated with diesel generators, which typically range from $8,000 to $15,000 per year. Additionally, deferring generator replacements can save another $10,000 to $20,000 annually.
Who Loses? Diesel Generator Suppliers
As municipalities pivot to battery systems, traditional diesel generator suppliers face declining demand. The shift not only impacts their market but also the associated maintenance and fuel supply sectors. This transition signals a broader trend towards cleaner energy solutions.
Long-Term Viability: A Sustainable Investment
The Viridi battery packs are engineered for longevity, rated for 4,000 full charge-discharge cycles. In applications like the Erie County Pumping Station, the system is expected to last over 20 years. This durability further enhances the ROI, making the initial investment increasingly attractive.
Safety and Reliability: A Fail-Safe Design
Viridi’s proprietary Fail-Safe Anti-Propagation™ architecture ensures that any thermal failure within a cell does not propagate to others, mitigating fire risks. This safety feature is crucial for deployment in sensitive infrastructure areas, enhancing public confidence in battery technology.
Future Outlook: Accelerating Adoption Across Municipalities
As federal and state incentives remain robust, the expectation is that more municipalities will adopt BESS to replace diesel generators. Viridi’s New York State Infrastructure Hardening & Modernization Program is already paving the way for broader deployments. The focus on resilience and emissions reduction will drive this trend further.
