Grid monitoring
where it’s most needed

We partner with government agencies, funders, power providers, and researchers to provide accurate, timely data about energy systems. Our custom sensors, analytics, and expertise help customers better focus their investments into grid infrastructure.

Our process

What does working with us look like?

We work with partners on incremental projects, or large-scale deployments. Projects usually follow four steps.

We build local teams to deploy our custom sensors in residents’ homes, and in key locations for accurate data collection.

Our work

Sensor deployment projects

For the past 5 years we’ve been refining our methodology and deploying it to real effect in Ghana, Kenya, Uganda, Rwanda, the Democratic Republic of the Congo, Nigeria, and Sierra Leone.

Why it matters

Better data means better outcomes for everyone

Clearer operational visibility

With our sensors deployed, utility providers can better understand where the grid is weakest and respond accordingly.

Improved long-term planning

Government agencies, funders, power providers, and researchers can use our data to better prioritize investments and evaluate real program outcomes.

Better service for citizens

At the end of the day, people get better service when the infrastructure they rely on is monitored.

Using Power Source Detection as Evidence for the Energy Transition

Renewable and hybrid energy systems are expanding rapidly across sub-Saharan Africa—but proving their real climate impact remains a challenge. This blog outlines why this verification gap matters and shows how nLine uses high-frequency voltage and frequency data to measure when solar is truly replacing diesel, enabling more credible emissions accounting and unlocking pathways to climate finance.

Characterizing Healthcare Power Quality: Exploratory Findings from the MetaFridge Dataset

This post introduces the MetaFridge dataset - a high-resolution collection of voltage and frequency measurements from vaccine refrigerators deployed across public health facilities in Kenya - and illustrates its value through a case-study analysis of data from 2023.

Could improving power quality boost economic growth in Sierra Leone?

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.
