Two project records, different stages
On 10 September 2026, the Jiangsu Provincial Department of Ecology and Environment issued an environmental-impact approval for the first phase of the Guohua Dongtai Zhugensha Z1 offshore PV pilot. The approval describes a 500 MW station with a 646.86 MWp DC PV field, within a larger phased plan. It also states that construction may not start until the nearshore sea environmental-function zoning adjustment is approved or cancelled. The approval is therefore a dated environmental milestone, not evidence that the project has started construction or is operating.
A 21 September Yancheng notice for the Guohua Jiangsu Dafeng H12 offshore project described a 303.6 MW proposal under review. A notice of a proposed approval is a different status from a final approval, construction or commissioning. Keep the authority, project phase and notice wording beside each capacity figure.
Separate site decisions from policy claims
Environmental decisions concern named projects and documents. They do not, by themselves, establish a national policy requirement or prove that a whole offshore pipeline has been approved. A policy claim should identify its issuing authority, document, relevant provision and date; a project notice should be described at the milestone it actually records.
This distinction also matters when comparing offshore proposals with floating PV elsewhere. Site exposure, ecological conditions, grid connection, marine works and approval conditions vary. A project count or planned capacity should not be treated as commissioned supply or as a procurement order forecast.
What project teams should check next
For an equipment or delivery discussion, verify the latest environmental decision and its conditions, land or sea-use approvals, grid-connection arrangements, issued design and procurement schedule. Record whether capacity is stated on the AC or DC side and whether it refers to one phase or the full plan.
The next useful update is a new dated record, such as a final approval, notice to proceed, construction report or commissioning evidence. Keeping these milestones separate makes a project register more useful than repeating a single headline capacity as though it described current operation.
Frequently asked questions
Does the Dongtai environmental approval prove that construction has started?
No. The approval records an environmental decision and includes a condition that construction may not start until the specified nearshore zoning adjustment is approved or cancelled.
Was the 303.6 MW Dafeng H12 project finally approved on 21 September?
The cited Yancheng notice was a proposed-review notice. It should not be reported as a final decision or an operating project without a later record.
What does the Dongtai 500 MW figure describe?
The Jiangsu approval describes a 500 MW offshore station for the evaluated first phase and separately gives 646.86 MWp for the PV field on the DC side.
