Aquaculture professionals will see this page as a review, and we believe that reviewing basic concepts keeps us focused on fish health and profitability.
This page describes the operational potential of the site's power position, not the current state of on-site systems — see the disclosure at the bottom for what exists today. Every grow-out variable in a recirculating system has a biological optimum and an economic setpoint, and on the grid those two numbers are rarely the same. Energy is one of the largest controllable operating costs in a RAS, so operators commonly set temperature, oxygenation, pumping, and turnover at whatever level a power budget allows, rather than at the biologically ideal level. Abundant, low-cost power closes that gap.
The industry has a name for farming this way: precision aquaculture — running a system so temperature, oxygen, water chemistry, and lighting are held tightly to the fish's biological optimum rather than to a cost-driven compromise. Abundant, low-cost power is what makes it practical to run at scale.
Water temperature — Salmonid grow-out has a fairly narrow thermal window. Heating in a Maine winter and chilling in a summer heat wave are both power-hungry, so grid-dependent farms let temperature drift within a tolerable band. With this site's power position, an operator could hold the species-specific optimum to within a degree year-round, supporting faster, more uniform growth.
Dissolved oxygen — Oxygen is the ceiling on stocking density and the first thing to crash under load. Continuous oxygen generation and injection is one of the largest power draws in a RAS. Low-cost power would let an operator keep dissolved oxygen at or above saturation across every tank at peak biomass, rather than rationing oxygenation and capping density.
CO₂ stripping and degassing — As oxygen and biomass rise, dissolved carbon dioxide accumulates, depressing pH and stressing fish. Degassing towers and stripping blowers correct it — and they run on power. Farms that can't get their CO₂ down usually can't afford to run the blowers hard enough. This site's power position removes that constraint.
Water turnover and pumping — Exchange rate is waste removal, oxygen delivery, and uniformity all at once. More pumping means cleaner, more stable water and faster removal of metabolites. Pumping is the baseline power load of the entire facility — on the grid it gets throttled; with on-site generation it wouldn't need to be.
Filtration and disinfection — Ozone generation is electricity-intensive and is the difference between adequate water and genuinely clean, low-pathogen water. Running ozone and UV aggressively reduces disease pressure and standing bacterial load — fewer outbreaks, fewer downgrades at harvest.
Purified water on demand — Reverse osmosis is one of the most energy-intensive processes a farm can run. Seawater drawn from Prospect Harbor through the site's deeded easements could, with sufficient power, be purified on-site to whatever salinity a given life stage requires — purified seawater for grow-out, brackish water for smoltification, and fresh water for freshwater stages or off-flavor purging. (Seawater intake and discharge infrastructure is not yet constructed — see the disclosure below.)
Photoperiod and Early Maturation — Early sexual maturation drives chaotic tank behavior, welfare decline, and flesh-quality downgrades. Continuous LED lighting is an established tool for suppressing precocious maturation, and tightly controlled temperature is the other half of the equation. Both cost money to run continuously, so grid-dependent operators often choose one. A stronger power position would let an operator run both at once.
Reliability and Mortality Risk. A recirculating system can lose an entire crop in hours if pumping and oxygenation stop — there is no pond buffer. A robust on-site generation position, paired with backup, would reduce the likelihood of a catastrophic oxygen crash. For a buyer, that is a factor in protecting the value of a large standing biomass, not simply an operating-cost line.
Atlantic Sapphire, a land-based salmon producer, reported a 6.4% mortality rate in its 2024 Annual Report, compared with a 15.4% mortality rate reported for the conventional net-pen ocean aquaculture industry in Norway for the same year (Norwegian Veterinary Institute) — less than half the industry rate. The company attributes the improvement to environmental control, citing water temperature stabilization as a factor in the reduced mortality and improved growth it reported.
