Shaoxing, Zhejiang: Power grid upgrade boosts fisheries production

The recent completion of the 10 kV Tunan Line overhaul has brought relief to the aquaculture industry in Shaoxing's Haitu area in Gaibei town.

Project supervisor Gao Wang said that voltage fluctuations during peak hours used to cause aerators to falter, a source of great anxiety for farmers.

With the old lines now comprehensively upgraded, he confirmed that machinery is running steadily and power reliability has significantly improved, allowing fish farmers to operate with greater security.

As a key local aquaculture base, the Haitu area has seen its electricity demand surge with recent expansions in farming scale. The original power grid could not keep pace with the growing load, leading to frequent voltage instability and insufficient power, especially when aerators and feeders ran simultaneously during critical summer months. This instability directly threatened the stability and profitability of fisheries.

To address this, the Gaibei Power Supply Station of State Grid Shaoxing Power Supply Company proactively organized technical teams to conduct multiple on-site surveys early this year.

Staff member Liang Weilong explained that the teams carefully assessed the electrical equipment and identified operational bottlenecks for each fish pond to develop a targeted solution.

Based on this research, the station formulated an upgrade plan focused on replacing severely aged and undersized line sections. All preliminary work was finalized by early October, setting the stage for a smooth construction process.

During the construction phase, the project team implemented meticulous measures to minimize disruption. The team repeatedly optimized the construction plan, using alternate power routes and generators to shorten outage times.

The dual goal was to ensure both the quality of the upgrade and the continuity of the farmers' daily operations. This overhaul has not only enhanced the regional power grid's reliability but also provided stronger, more stable electricity support for the continued growth of aquaculture in the Haitu area.
