Rooftop photovoltaic systems and user‑side energy storage are proliferating, but before they can begin generating power, they must pass rigorous grid‑connection testing and acceptance procedures. Unlike conventional loads, PV systems and energy storage devices are active equipment; improper setting of grid‑connection parameters can not only impair their own operation but also jeopardize the safety and stability of the power grid. Consequently, demand for professional grid‑connection technical services has surged.
In the early stages of the project, the power‑technical service company is required to assist the owner in preparing and obtaining approval for the grid‑connection scheme, calculating short‑circuit currents, and verifying protection settings, thereby ensuring that the connection plan is economically sound and does not pose risks to the power grid. In the later phases of construction, technical personnel must employ specialized testing equipment to conduct power‑quality assessments, anti‑islanding‑protection tests, and tests of active‑ and reactive‑power regulation capabilities on inverters and power‑storage converters (PCS), confirming compliance with grid‑connection requirements.
Moreover, as provincial regulations tighten requirements for the dispatch and operation of energy storage systems, grid‑connection testing has become a mandatory prerequisite. This suite of high‑tech service offerings has opened up new business avenues for traditional power‑construction firms. By acquiring precision testing equipment and training specialized commissioning engineers, some companies have successfully entered this untapped market, expanding beyond mere equipment installation into higher‑value‑added grid‑integration services.

Qualification upgrades have become a competitive barrier, and the trend toward specialization in transmission and transformation projects is becoming increasingly pronounced.
As grid‑infrastructure development places ever‑higher demands on safety and quality, market‑entry standards have become increasingly stringent. Holding installation (repair, testing) permits and professional contracting qualifications issued by the National Energy Administration and the housing and urban–rural development authorities has become a fundamental prerequisite for bidding on major projects. The level of these qualifications not only reflects an enterprise’s capabilities but also establishes critical technical barriers in an intensely competitive market.

The explosive growth of photovoltaics and energy storage is giving rise to a new, untapped market for grid‑connection technical services.
Driven by the “dual carbon” goals, distributed photovoltaic systems and next‑generation energy storage projects are experiencing explosive growth. However, the large-scale integration of new‑energy assets into the grid poses significant challenges to grid‑connection safety and stability. This has given rise to a specialized market for technical services related to new‑energy grid integration—covering areas such as the development of connection system plans, grid‑connection commissioning and testing, and grid‑related trials—making it a burgeoning “new blue ocean” in the power‑technology services sector.

Serving Thousands of Industries: Divergent Needs in Electrical Installation Highlight the Need for Customization Capabilities
Different electricity‑use scenarios impose markedly distinct requirements on electrical installation. The heavily polluted environments of industrial and mining enterprises, the standardized replication typical of real‑estate projects, and the stringent reliability demands of data centers are all testing the ability of electrical‑installation firms to deliver differentiated, customized solutions. Deeply cultivating niche markets is becoming a key factor for power‑engineering companies in building their core competitive edge.
