Hydroelectric Plant
$57.1Sx base cost · $224T/sec
Business Overview
Power flowing like money.
The Hydroelectric Plant sits comfortably in the middle of the pack: cheap enough to stack early, strong enough to matter later.
Cost Scaling
Every business in Tycoon Cards uses the same cost curve: each copy costs 15% more than the last. For the Hydroelectric Plant, that looks like this:
| Copies owned | Cost of next copy | Total spent to reach this many |
|---|---|---|
| 1 | $65.6Sx | $57.1Sx |
| 10 | $231Sx | $1.16Sp |
| 25 | $1.88Sp | $12.1Sp |
| 50 | $61.8Sp | $412Sp |
| 100 | $67.0Oc | $447Oc |
Income Scaling
Income scales linearly with copies owned — no diminishing returns, ever. Owning more of the Hydroelectric Plant always earns proportionally more:
| Copies owned | Income per second |
|---|---|
| 1 | $224T/s |
| 10 | $2.24Qa/s |
| 25 | $5.60Qa/s |
| 50 | $11.2Qa/s |
| 100 | $22.4Qa/s |
Profit Calculations
| Payback period (1st copy) | 254,899,058 seconds |
| Income per dollar spent | $0.0/s per $1 |
| Efficient switch point | Around copy #4 (when the next copy costs more than Nuclear Plant) |

Unlock Requirements
There is no gating system on businesses in Tycoon Cards — the Hydroelectric Plant is available to purchase from the very start of any run, the moment you can afford its $57.1Sx base cost. The only realistic "requirement" is reaching that amount of money, either by clicking, by owning cheaper businesses, or by carrying prestige and card bonuses from a previous run.
Best Upgrades
Individual businesses don't have their own upgrade trees in Tycoon Cards — the Hydroelectric Plant always earns exactly $224T per copy at base rate. What actually "upgrades" its value are the game's shared systems: levelling supporting cards (below), earning achievement bonuses, and increasing your prestige multiplier. Each of these applies as a percentage on top of every business you own, including this one.
Best Supporting Cards
At this tier, all-income and passive-income cards deliver the biggest absolute gains, since a percentage bonus on a high-earning business is worth far more in raw dollars than the same percentage on a cheap early tier.
Prestige Recommendations
Owning multiple copies of this tier usually means you're in the later half of a run — a reasonable point to start planning your next prestige once growth visibly slows.
Read the full Prestige Guide for general reset timing, or the Prestige Point Planning guide to calculate exactly how many points your next reset will earn.
Research Interactions
Tycoon Cards does not currently include a research-tree system — the Hydroelectric Plant cannot be researched or unlocked through any mechanic beyond simply affording it. A research tree is listed as a possible future system on our Updates & Roadmap page; this section will be updated if that ever changes.

Best Strategies
- This tier represents serious income — prioritise it once your card bonuses are strong enough to make the large upfront cost worthwhile.
- Watch the payback period column below; once it drops to a reasonable window relative to your play session length, it's worth investing.
- Remember that all businesses share the same 15%-per-copy cost curve, so the fundamental buy/hold maths never changes — only the absolute numbers do.
