The productive capacity of electrical generators operated by utility companies is often measured in MW. Few things can sustain the transfer or consumption of energy on this scale; some of these events or entities include: lightning strikes, naval craft (such as aircraft carriers and submarines), engineering hardware, and some scientific research equipment (such as supercolliders and large lasers).
For reference, about 10,000 100-watt lightbulbs or 5,000 computer systems would be needed to draw 1 MW. Also, 1 MW is approximately 1360 horsepower. Modern high-power diesel-electric locomotives typically have a peak power of 3–5 MW, while a typical modern nuclear power plant produces on the order of 500–2000 MW peak output.

| 10$^{46}$ | | 1 × 10$^{46}$ W | astro: record for maximum beaming-corrected intrinsic luminosity ever achieved by a gamma-ray burst |
| 10$^{47}$ | | 7.519 × 10$^{47}$ W | phys: Hawking radiation luminosity of a Planck mass black hole |
| 10$^{48}$ | | 9.5 × 10$^{48}$ W | astro: luminosity of the entire Observable universe ≈ 24.6 billion trillion solar luminosity. |
| 10$^{49}$ | | 3.6 × 10$^{49}$ W | astro: peak gravitational wave radiative power of GW150914, the merger event of two distant stellar-mass black holes. It is attributed to the first observation of gravitational waves. |
| 10$^{52}$ | | 3.63 × 10$^{52}$ W | phys: the unit of power as expressed under the Planck units, at which the definition of power under modern conceptualizations of physics breaks down. Equivalent to one Planck mass-energy per Planck time. |
