Independent auditors of the world’s critical infrastructure

In this post, we present findings from a nine-month study in Freetown, Sierra Leone, using GridWatch sensors deployed in 48 businesses across 12 transformers. The study reveals that MSMEs in eastern Freetown experienced nearly seven times more outage hours than those in western Freetown, with businesses experiencing an average of 300 hours of outages per month. The post highlights how improving power quality and reliability could raise utility revenues, support capacity planning, and unlock investment for economic growth.

In this post, we describe findings from measuring both hospital- and room-level KPIs, uncovering that different rooms or departments within healthcare facilities experience varying PQR outcomes. In doing so, we highlight the importance of considering room-level KPIs, especially in critical rooms, alongside hospital-level metrics to more accurately measure healthcare electrification outcomes.

In 2022, the five-year, $316 million Ghana Power Compact came to a close. nLine sensor data supported the evaluation of a line bifurcation project under the Compact. This blog is adapted from Millennium Challenge Corporation’s (MCC) final learnings from this impact evaluation and highlights lessons for the design of future power infrastructure programs.
