The Three Gorges Dam: Is it a Cash Cow?

The Three Gorges Dam: Is it a Cash Cow?

The Three Gorges Dam. Just the name conjures up images of a colossal structure, a modern wonder straddling the mighty Yangtze. It’s more than just a dam; it’s a symbol of China’s ambition, a testament to engineering prowess. But beyond the concrete and steel, lies a big question: how much moolah does this thing actually rake in each year?

Well, the financial story of the Three Gorges Dam is more than just about selling electricity. Sure, that’s a huge part of it, but there are other ways it brings in the bacon.

First off, let’s talk power. This dam isn’t playing around. With its 34 generators humming away, it’s like the world’s biggest power plant, capable of churning out some serious juice. We’re talking an average of 95 terawatt-hours (TWh) of electricity annually. To put that in perspective, that’s enough to power a whole lotta homes! And get this – in 2020, after some seriously heavy monsoon rains, it cranked out nearly 112 TWh, smashing all previous records. Not bad, eh?

But it’s not just about electricity. Think about shipping. Before the dam, navigating the Yangtze was a bit of a headache. Now, with the ship locks in place, it’s like a superhighway for boats. We’re talking about a tenfold increase in shipping capacity, which slashes transportation costs by a whopping 30 to 37%. That’s a huge win for businesses along the river.

And who can forget tourism? People flock from all over to gawk at this behemoth. It’s become a major attraction, injecting even more cash into the local economy.

So, how do we put a number on all this? How much does the Three Gorges Dam actually earn?

Okay, let’s crunch some numbers. In 2021, the dam generated a staggering 103.65 billion kWh of electricity. Now, back in 2002, the price of electricity from the dam was around ¥0.25 per kWh. Prices may have shifted since then, but if we use that as a rough guide, we’re looking at a cool ¥25.91 billion (roughly US$3.8 billion) from electricity sales alone.

But wait, there’s more! Some reports suggest the dam’s total annual income is actually over ¥50 billion (US$7.3 billion), with net profits hitting ¥20 billion (US$2.9 billion). I even saw figures from 2018 showing an income of ¥51.2 billion (US$7.5 billion) and a net profit of ¥22.6 billion (US$3.3 billion). Not exactly chump change!

Of course, these numbers can bounce around depending on things like rainfall (gotta have water to make power!), electricity demand, and government pricing policies. It’s not an exact science.

Now, let’s not forget that building this thing was a seriously expensive undertaking. We’re talking an initial estimate of ¥180 billion (US$22.5 billion), which eventually ballooned to ¥249 billion (US$37 billion). That’s a lot of zeroes! The money came from all sorts of places – special construction funds, profits from another dam (the Gezhouba), loans, and even bonds.

But here’s the kicker: they figured they’d recoup the costs after generating 1,000 terawatt-hours (TWh) of electricity, bringing in ¥250 billion. And guess what? By December 20, 2013, they’d paid off the whole shebang! As of October 2024, the dam had generated 1.66 trillion kWh of electricity, resulting in an accumulated income of around ¥300 billion (US$44 billion). Talk about a good investment!

But the story doesn’t end there. The Three Gorges Dam’s impact goes way beyond just the money it makes directly.

Think about flood control. The Yangtze used to be notorious for its devastating floods, causing billions in damages. The dam helps to tame the river, protecting homes, farms, and businesses. That’s a huge economic benefit, even if it’s hard to put a precise dollar figure on it.

And then there’s navigation. With the improved shipping conditions, trade along the Yangtze has exploded, especially benefiting inland cities like Chongqing. It’s like the dam unlocked a whole new level of economic activity.

The dam has also spurred development in the surrounding region, creating jobs and boosting the local economy. And let’s not forget the environmental angle. By generating clean hydroelectric power, the dam helps to reduce our reliance on coal, cutting down on nasty emissions like carbon dioxide and sulfur dioxide.

Of course, it’s not all sunshine and roses. The Three Gorges Dam has faced its fair share of criticism.

The biggest issue is the displacement of people. Over 1.3 million people had to be relocated to make way for the dam, raising serious questions about resettlement and compensation. And there are concerns about the dam’s impact on the environment, including downstream sediment levels, riverbank stability, and the potential for landslides.

So, what’s the bottom line? The Three Gorges Dam is a money-making machine, no doubt about it. It generates billions of dollars in revenue each year, and its economic impact stretches far and wide. But it’s also a complex project with significant social and environmental consequences. It’s a story with both triumphs and tragedies, a reminder that even the most impressive engineering feats can have unintended consequences.
