An iconic skyline in the Chinese city of Shanghai - called The Bund - will not be lit for two nights to save power, officials say.
The waterfront region is a well-liked tourist destination because of its blend of ancient and cutting-edge structures.
Major manufacturers in the Sichuan area of China told the BBC that they had experienced power outages.
Severe drought and record-breaking heat waves are affecting large portions of the second-largest economy in the world.
Buildings in the Bund, which are situated along the city's biggest river, won't be illuminated on Monday and Tuesday, according to a notice published on Sunday by the Shanghai Landscaping and City Appearance Administrative Bureau.
The notice stated, "We sincerely apologize for any inconvenience this may have caused."
After Sichuan in southwest China and Shanghai in the Yangtze Delta region endured weeks of intense heat, China last week issued its first national drought notice of the year.
In a recent statement, officials in the Sichuan province, where temperatures have above 40C (104F), said that the power shortages were a result of a combination of factors including poor rainfall, high temperatures, and increased demand for air conditioning.
According to news reports, the province has prolonged its energy conservation measures until Thursday by five days. The electricity supply to some industrial firms is constrained by these.
Volkswagen, a German automaker, informed the BBC that its Chengdu factory is still closed. Chengdu is the capital of Sichuan.
A representative for Volkswagen said the company anticipates "a minor delay" in delivery, which it could make up for "shortly."
The representative continued, "We are closely communicating with our suppliers and are closely monitoring the situation."
Foxconn, an Apple supplier that shut down its Sichuan plant as well, claimed the effect on its present production was "not significant."
In the meantime, Toyota, the world's largest automaker, informed the BBC that it was "utilizing in-house power generation" to gradually resume manufacturing in Sichuan.
According to Chenyu Wu, an associate analyst at consultancy Control Risks for China and North Asia, the effects of power outages are expected to be transient.
"Local initiatives to save electricity and improve generation are likely to help ameliorate the power deficit scenario in the coming weeks," he said, especially if the hot, humid weather finally breaks.
Amid the country's longest heatwave on record, authorities have taken steps to artificially create rainfall in several areas of central and southwest China.
Local media reports that Hubei and several other provinces have fired rockets carrying chemicals into the sky to counteract the drought that has affected the region surrounding the Yangtze River, Asia's longest waterway.
In some places, though, attempts to do the same have halted due to a lack of cloud cover.
