We believe everyone deserves reliable infrastructure

Lack of stable infrastructure is unfairly holding back huge portions of the world’s population from running businesses, preparing food, and accessing safe and reliable healthcare.

We care deeply about bringing the benefits of modern systems, inclusive decision-making, and open information to everyone.

Founded at UC Berkeley,
now a global team

In 2017, nLine started in the Electrical Engineering department of University of California, Berkeley where Josh and Noah, two of our co-Founders received their PhDs, and Prabal, our third co-founder, is a faculty member. Since then, we’ve grown both in Berkeley and across the globe with a talented team of people.

Working with the garage door open

Drawing from our academic roots, we try to publish everything we learn - from papers, to conferences, to blog posts. We always love to get in touch with others pushing towards similar goals.

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.

From Measurements to KPIs: Estimating SAIDI at nLine

How can we estimate SAIDI (System Average Interruption Duration Index)—the average power outage duration experienced across all customers served—from PowerWatch sensor measurements of only a subset of customers? This post describes nLine’s statistical approach to estimate SAIDI from such a dataset. The nLine method has several favorable statistical properties that make it well-suited to calculating SAIDI in the real world where data is generally limited, which traditional SAIDI calculations neglect to consider.
