• Pinyin (with tone marks): diànwǎng
• Part of Speech: Noun
• HSK Level: HSK 6
• Concise Definition: An interconnected network for delivering electricity from producers to consumers.
• In a Nutshell: 电网 (diànwǎng) is the direct and standard term for the “electrical grid” or “power grid”. It refers to the entire system of power plants, high-voltage transmission lines, substations, and local distribution wires that bring electricity to homes and businesses. While it's a technical term, it's commonly heard in news reports about national development and used in everyday life when discussing power supply or outages.

• 电 (diàn): This character originally depicted lightning under a cloud. Today, its primary meaning is “electricity,” “electric,” or “lightning.”
• 网 (wǎng): This is a pictograph of a net, clearly showing the crisscrossing lines. It means “net” or “network.”
• The characters combine logically and visually: an “electricity net” (电 + 网) creates the perfect word for the vast, interconnected network that is the electrical grid.

The 电网 (diànwǎng) in China is more than just infrastructure; it's a potent symbol of national strength, rapid modernization, and state-led development. Unlike the often fragmented and privately-owned power grids in many Western countries like the United States, China's grid is centrally planned and controlled by two colossal state-owned enterprises: the State Grid Corporation of China (国家电网) and the China Southern Power Grid (南方电网). This centralized approach allows for massive, ambitious projects, such as the construction of the world's most extensive ultra-high-voltage (UHV) transmission lines, which move power from remote energy-rich regions in the west to the populous industrial centers in the east. For Chinese citizens, a stable and ever-expanding 电网 is a source of national pride and a tangible benefit of the country's economic model. It represents the state's ability to mobilize resources to achieve monumental engineering feats for the collective good, a value deeply rooted in a collectivist mindset. Discussions about the 电网 often carry a sense of scale and ambition that reflects China's position on the world stage.

The term 电网 is used in both formal and informal contexts, though it carries a slightly technical feel.

• In the News: Media reports frequently use 电网 when discussing economic development, energy policy, disaster recovery (e.g., “repairing the grid after a typhoon”), and technological advancements like “smart grids” (智能电网).
• Everyday Conversation: While someone might more commonly say “the power went out” (停电了, tíngdiàn le), they would use 电网 when discussing the *reason* for the outage, especially if it's a systemic issue. For example: “The summer heat is putting a lot of pressure on the power grid.” (夏天的高温给电网带来了很大压力).
• Connotation: The term is overwhelmingly neutral to positive. A “strong” or “stable” grid (稳定的电网) is seen as a sign of a well-functioning society.

• `电网 (diànwǎng)` vs. `电线 (diànxiàn)`: This is a crucial distinction. 电网 refers to the entire *grid* or *system*. 电线 (diànxiàn) refers to a single “electrical wire” or “cable.” A learner might mistakenly point to a power line and call it the `电网`.
  • Incorrect: `你看，那根电网断了！` (Nǐ kàn, nà gēn diànwǎng duàn le!) → “Look, that power grid is broken!”
  • Correct: `你看，那根电线断了！` (Nǐ kàn, nà gēn diànxiàn duàn le!) → “Look, that power line/wire is broken!”
• `电网 (diànwǎng)` vs. `网络 (wǎngluò)`: Both contain the character `网` (net), but they are not interchangeable. 网络 (wǎngluò) almost exclusively refers to the “internet” or other computer/communication networks. Using it to mean the power grid is a common mistake.
  • Incorrect: `停电了，肯定是网络出问题了。` (Tíngdiàn le, kěndìng shì wǎngluò chū wèntí le.) → This sounds like “The power is out, the internet must have a problem.” (While possibly related, the cause is stated incorrectly).
  • Correct: `停电了，肯定是电网出问题了。` (Tíngdiàn le, kěndìng shì diànwǎng chū wèntí le.) → “The power is out, the power grid must have a problem.”
