FuelCell Energy, Inc. v. Groton
Annotate this Case
The plaintiff, a company that constructs and operates fuel cells, sought municipal property tax exemptions for its fuel cell modules and related equipment installed on the Pfizer campus. The property primarily provided electricity and converted waste heat into thermal energy. The plaintiff applied for tax exemptions under Connecticut General Statutes § 12-81 (57), which exempts class I renewable energy sources from taxation. The defendant, the town of Groton, denied the applications, classifying the property as a cogeneration system under § 12-81 (63), which allows but does not require municipalities to exempt such systems from taxation.
The Superior Court granted partial summary judgment to the plaintiff, ruling that the property was exempt from taxation for the years 2017 through 2019 under § 12-81 (57). The court found that the property, which included fuel cells with a heat recovery steam generator (HRSG), fell within the definition of a class I renewable energy source. For the 2016 tax year, the court held a trial and determined that the property was not completely manufactured by October 1, 2016, and thus was exempt under § 12-81 (50) as "goods in the process of manufacture." The court also ruled that the plaintiff was not required to file a personal property declaration for the exempt property, and the penalties imposed by the defendant for failing to file such a declaration were improper.
The Connecticut Supreme Court upheld the trial court's rulings. It agreed that the property was exempt from taxation under § 12-81 (57) for the years 2017 through 2019, as the statute specifically exempts class I renewable energy sources, including fuel cells. The court also affirmed that the property was exempt for the 2016 tax year under § 12-81 (50) as it was still in the process of manufacture. Finally, the court held that the plaintiff was not required to file a personal property declaration for the exempt property, and the penalties for failing to do so were not permitted.
