Shanghai Electric Nets 78 MW Solar-Fishery in China

• Shanghai Electric’s 78‑MW solar‑fishery marries floating PV and canopy‑cooled ponds, smart O&M and grid support—battery-ready, algae-taming, tariff-shifting power plus aquaculture profits with marine-grade resilience.

A Shanghai Electric–led consortium will build a 78‑MW solar‑fishery project in China, combining floating PV arrays with elevated canopies over ponds. Corrosion‑resistant floats stabilize platforms; canopies cut evaporation, moderate water temperature, and curb algae. String inverters and SCADA enable rapid fault isolation and tighter O&M as boat access slows repairs.

Grid features include reactive power, LVRT/HVRT, and ramp‑rate control via a controller. A battery‑ready substation anticipates two‑to‑four‑hour storage to shift output to evening tariffs and provide frequency response. Revenues pair power sales with aquaculture; risks are reduced by standardized designs, UV‑resistant polymers, marine‑grade fasteners, thermography, biofouling monitoring, and float inspections.

How does Shanghai Electric's 78‑MW solar‑fishery optimize O&M, grid support, and revenue?

O&M
- Predictive analytics on inverter/string data to forecast failures, pre‑stage crews/spares, and trigger remote resets
- Drone thermography, IV‑curve sweeps, and ROV checks for modules, moorings, and submerged cabling
- Digital twin + CMMS for condition‑based maintenance, parts kitting, and SLA tracking
- Modular raft sections with quick‑disconnect DC/AC harnesses to shorten swaps and isolate faults
- Stray‑current and corrosion monitoring with sacrificial anodes and potential probes; cable bend‑radius and chafe controls
- Robot or brush‑boom cleaning for surface debris and biofilm; scheduled weed‑boom skimming around arrays
- Redundant fiber/4G comms rings, secure VPN access, and over‑the‑air firmware updates
- Weather‑aware work windows, floating walkways/berths, and standardized lock‑out/tag‑out for boat crews

Grid support
- Plant controller coordinates Volt/VAR, voltage droop, and active‑power ramping for feeder stability
- Fast frequency response and synthetic inertia from inverters; active power curtailment with forecast‑based smoothing
- Dynamic power‑factor setpoints at PCC, harmonic filtering, and flicker control
- Ride‑through, anti‑islanding, and fast fault current limiting to meet grid codes
- Day‑ahead/intraday production forecasts to the dispatcher and AGC participation readiness
- Storage‑ready architecture (AC or DC coupled) with EMS hooks for grid‑forming mode when batteries are added

Revenue
- TOU‑aligned PPAs and merchant uplift via price‑responsive dispatch; arbitrage and ancillary services once storage is online
- Curtailment hedge by shifting on‑site loads (aerators, pumps, chillers) to midday surplus
- Co‑use income from aquaculture leases; species/stocking optimized for shaded ponds to improve feed conversion and survival
- Green certificates/carbon credits stacked with energy sales; eco‑labeling to premium‑price seafood
- Operations outsourcing for nearby ponds and forecasting/data services for farm energy management
- Lower insurance and financing costs through standardized design, monitoring, and documented risk controls
- Community/tourism partnerships and education programs to diversify site revenue
