nLine’s Blog

Our team is motivated by a belief that better data on grid reliability is critical to support urban and community energy resilience in low- and middle-income countries. We care deeply about global energy justice and believe reliable, critical infrastructure is a fundamental human right.

This blog is a space to host our work, ideas and perspectives in the global effort to provide reliable access to electricity for all.
