Nexus-trained start-up SusTech Innovations advances energy security
through smart electricity management.

As global energy demands rise, SusTech Innovations Pvt Ltd is stepping
up with smarter ways to track and optimize electricity consumption.
This Hyderabad-based start-up helps power-intensive industries
monitor their energy use in real time and improve efficiency without
relying on third-party meters.
Trained at the U.S. Embassy New Delhi’s Nexus Startup Hub, SusTech’s
patented Internet of Things (IoT)-based system called EEMAC (Electrical
Energy Measuring, Monitoring and Control). EEMAC tracks energy flow,
detects inefficiencies and helps prevent overuse— resulting in reduced
costs, less waste and a lighter load on the power grid.
SusTech’s work aligns with the United States and India’s commitment
to accelerating innovation through the TRUST (Transforming
Relationship Utilizing Strategic Technology) initiative—announced in
the U.S.-India Joint Leaders’ Statement —and is supported by the Nexus
Startup Hub, which connects start-ups, innovators and investors with
networks, training, mentors and funding.
Smarter energy for all
SusTech began with a clear goal of tackling rising energy demand
through smarter consumption. “We noticed a major gap in energy
efficiency at the consumption level due to outdated infrastructure,
unmonitored usage and lack of consumer awareness,” says founder-
director Vijaya Kumari Kakarla .
SusTech’s solutions aim to shift how people view energy use, moving
from passive consumption to conscious, optimized management. Its
flagship product EEMAC captures and relays real-time electrical data
like voltage, current and power factor, which can be accessed by users
through its mobile or web apps. This data, stored on a secure cloud
platform, offers users insights and alerts for anomalies, overuse or
inefficiencies.
Unlike standard smart meters, EEMAC also allows for load control,
remote disconnection and automation, and works across multiple
sectors, from households to heavy industry. “With predictive
diagnostics and encrypted data handling, EEMAC provides a proactive,
independent approach to energy optimization,” says Kakarla.
While many start-ups offer basic data dashboards, SusTech adds
intelligence and automation. “We enable users to measure, monitor,
control, set thresholds, auto correct power factor, detect theft and
schedule loads,” she says.
The system’s modular design makes it easy to scale. “We make energy
visible and manageable, empowering users to reduce costs, cut
emissions, and increase safety,” Kakarla explains. “In multiple field
tests, users saw measurable reductions in energy bills.”
Mentored for global impact
Kakarla credits Nexus with refining SusTech’s vision. “The Nexus Startup
Hub was pivotal in shaping SusTech’s strategic direction,” she says. The
program connected the team to global mentors and policy experts.
“We refined our product based on real customer feedback, aligned with
U.S.-India energy priorities, and learned to scale responsibly,” says
Kakarla.
SusTech has its eyes on international markets, especially the United
States, where they are exploring collaborations with energy incubators,
universities and grid modernization hubs. “Our goal is to offer scalable,
affordable energy intelligence that aligns with U.S. modernization
efforts,” she says.
Future-ready solutions
SusTech continues to innovate. One of its latest offerings is the
Transformer Health Monitoring and Controlling System (THMC), tested
by the Central Power Research Institute, Bengaluru.
“THMC uses smart sensors to monitor transformer oil, temperature and
load stress, which helps prevent failures and improve grid resilience,”
says Kakarla. Their new analytics tool also forecasts peak loads and
optimizes energy use through automation, thus reducing distribution
losses, improving system longevity, and enabling a smart and secure
energy infrastructure.
