Better data for better power grids

Across the globe, nearly 800 million people cannot access electricity, while billions live with unreliable and intermittent sources of power.

We’ve built a technology platform that provides utilities, regulators, governments, and funders access to accurate and cost-effective data about power grids, enabling them to better detect issues and prioritize investments.

Turn-key remote monitoring, made possible

With our GridWatch technology, you’ll have access to power quality and reliability data within weeks. More information about the key performance indicators (KPIs) that we use can be found in our brief below.

Sensor installation and data collection

Our robust sensors are plugged into outlets in residential homes or critical public infrastructure, such as healthcare facilities and collect data about electricity reliability and power quality.

Deployment monitoring

Our team of trained field staff are automatically notified when sensors go down and follow our robust deployment methodology to ensure GridWatch continues to collect high quality data.

Generating high-level KPIs

Sensor data is aggregated and filtered into grid-wide metrics like SAIDI and SAIFI and key power-quality insights about specific infrastructure, all viewable on live-dashboards.

Robust sensors gather power quality and reliability data

Sensors plug into a standard outlet and collect data about power reliability and quality. They report that data over the cellular network using a universal SIM, store the data locally in times of poor network quality, and include a battery so they are ready to collect data even after long outages.

Insight-forward analytics pipeline

Our standard data analysis tools provide grid-wide performance metrics about outages and voltage and display those in live, interactive dashboards.

How it all fits together

GridWatch gives you all the pieces you need to monitor grids.

Reliable, continuous data

Our sensors have been designed to work in any environment, handling extended outages or real-world complexities like accidental unplugging or periods of low-voltage.

Real-time feedback

Utility providers can get data about the performance of specific infrastructure to better target maintenance and improvements.

Works in any context

Our platform has been tested on large national grids, in healthcare facilities, and on mini- and micro-grids of renewable energy installations.

KPI reporting

Summarize historical data into continuous reporting on SAIFI, SAIDI and others to quickly evaluate the overall health of the grid.

Voltage quality

See average voltage, spikes and sags (brownouts) by district, by neighborhood, and by time period.

Low-touch install and operation

Our sensors are designed to be easy to install and minimize the need for replacements, so initial deployments are easy, and ongoing care is too.

Designed for Sub-Saharan Africa

Unlike generic power measurement platforms, nLine’s methodology is specifically designed to work in Sub-Saharan Africa and handle the operational challenges unique to it.

No modifying existing infrastructure

nLine's sensors can be deployed without any change to existing infrastructure, allowing for independent monitoring of utility companies.

See us in action

We’ve deployed over 2,500 sensors across 9 different countries. Read our case studies to see the impact it’s had for others.

Power Quality Data for Energy Planning in Nigerian Markets

Nigeria, the largest economy in Africa, has ambitious plans to reform its power sector and increase electrification. One piece of this strategy is the federal government’s Energizing Economies Initiative (EEI), which aims to provide electricity solutions to small and medium-sized enterprises (SMEs) in “economic clusters” such as markets, shopping complexes, and agricultural/industrial clusters. In many developing regions, SMEs in the informal sector play a major role in the economy. Nigeria is no exception: these enterprises employ millions of people. Providing affordable and reliable electricity to these marketplaces is important for continued economic growth.

What Can Voltages Tell Us About the Structure of the Grid?

Knowing the structure of the grid—how lines interconnect and what phases loads are on—is vital for efficient grid maintenance and operations, informing applications ranging from fault localization to phase balancing. Yet, grid structures, especially in distribution, can change over time and are often poorly known. This blog starts to explore how nLine’s voltage data could be used to infer grid structure, with a vision toward eventually providing such insight to utilities.
