Casella Waste Systems and Waga Energy have launched a renewable natural gas facility at the Hyland Landfill in Angelica, New York. The project uses Waga's WAGABOX technology to upgrade landfill gas into pipeline-quality renewable natural gas, which is injected into the Eastern Gas Transmission and Storage network. The facility has a processing capacity of 3,000 standard cubic feet per minute and can produce up to 610,000 MMBtu, or 180 GWh, of renewable natural gas annually. It is expected to eliminate the equivalent of 47,000 tons of carbon dioxide emissions per year based on EPA standards. This is the second of three RNG projects developed by Casella and Waga to come online, following a similar facility in Chemung County. Waga funded construction and will own and operate the site for 20 years, with revenue shared between the two companies. The project is expected to qualify for Investment Tax Credits and Production Tax Credits under the Inflation Reduction Act, which likely improves its financial viability.

Good to see landfill gas getting upgraded to pipeline quality. The 47k tons CO2 equivalent per year is a solid number. Curious how the IRA tax credits factor into the economics here.

The 610,000 MMBtu annual output is about 180 GWh, which is decent. But I'd like to know the capacity factor and how long the gas supply from the landfill will last. Landfill gas declines over time, so the 20-year operation might see declining output.

The ITC and PTC eligibility through the IRA is key. That likely made the project viable. But the emissions reduction claim depends on the baseline. Are they comparing to flaring or to venting? The EPA standard helps but it's worth checking the methodology.

This is the second RNG project from Casella and Waga this year. They are scaling up. The fact that it's injected into the Eastern Gas Transmission network means it can displace fossil gas regionally. Good for the grid.
