About Cumulus Data

Zero-carbon, affordable, reliable electricity

The Cumulus Data Mission.

We intend to advance the world’s transition to clean energy by leading the environmental, social, and governance (“ESG”) transformation of the power and digital infrastructure sectors.

We believe the electrification of the world is accelerating as a result of technology adoption in nearly every aspect of human life and economic activity. This technology adoption has resulted in the accelerating convergence between the growth of digital infrastructure assets, such as hyperscale cloud data centers, and increasing technology consumer demand for (1) zero-carbon, (2) low-cost, and (3) reliable electricity required to power technology applications. We call this the “trilemma” that faces digital infrastructure electricity consumers, as there are currently few options in the marketplace that fulfill these three requirements at once. We intend to help solve this trilemma through our Talen - Cumulus Data Platform.
