Built for how your sector runs

Utility software for meters, assets and customers

We build metering platforms, solar and grid monitoring, field service apps and consumer portals for power, water, gas and renewable energy operators.

Data-driven operations for energy and utilities

Utilities are moving from monthly meter readings and paper work orders to continuous data. Smart meters, SCADA systems, inverters and IoT sensors now produce readings every few minutes. The challenge is turning that stream into decisions: spotting losses, dispatching crews to the right fault and giving consumers clear bills and usage insights.

We work with power distribution companies and their system integrators, city gas distributors, water utilities, solar EPC firms, rooftop solar installers and renewable energy developers. Projects include meter data management, consumer apps for billing and complaints, solar plant monitoring, field workforce apps, asset registers with GIS maps and energy analytics for commercial and industrial users.

Nexzem builds data pipelines that handle high-volume time-series readings and integrate with existing billing, SCADA and GIS systems through standard interfaces. Field apps work offline in remote areas. Consumer-facing apps support regional languages and WhatsApp communication through NexChat, so bill alerts and outage notices reach people where they already read messages.

Regulations energy software must support

In India, the Electricity (Rights of Consumers) Rules set timelines for services such as new connections and complaint resolution, require online applications and round-the-clock support, and provide for compensation when timelines are missed, so utility systems must track each request against its deadline. The Revamped Distribution Sector Scheme is driving large smart prepaid metering rollouts, and meter data follows the DLMS/COSEM standard as adopted in Indian standards.

The Central Electricity Authority has issued cyber security guidelines for the power sector, and critical systems face strict network separation. Rooftop solar adoption depends on net or gross metering regulations issued by each state electricity regulatory commission. This is general information, not legal advice; confirm obligations with your regulatory team. Plan these controls early in procurement.

  • Track every consumer request against its regulatory timeline.
  • Support DLMS/COSEM meter data and head-end integrations.
  • Separate operational technology networks from corporate IT.
  • Keep consumer data accurate and accessible in self-service.
  • Report reliability indices from source data, not manual entry.
  • Keep a full audit trail of tariff and billing rule changes.

Integration challenges in utilities

Utilities run a dense landscape: head-end systems that talk to meters, a meter data management system, billing such as SAP IS-U, GIS for network assets, SCADA and distribution management for operations, call center and CRM tools, payment channels and field workforce apps. Each was often bought separately, and consumer and asset identifiers rarely match across them, which causes billing disputes and slow outage response. Each mismatch eventually reaches a consumer as a complaint.

Standards such as the IEC Common Information Model help define shared data structures, but most projects still need an integration layer with careful identifier mapping and data quality checks. Start with the flows that touch consumers most, such as meter to bill and complaint to field crew, and measure errors and turnaround times before and after.

Data quality work is unavoidable. Meter-to-consumer and consumer-to-transformer mappings are often incomplete, so projects should include field verification campaigns and tools that let crews correct asset and connection data from their phones. Every analytics and AI initiative depends on this foundation being reliable.

Where AI fits in energy and utilities

Load forecasting improves power purchase and scheduling decisions, while solar generation forecasting helps manage the variability of renewable sources. Smart meter data reveals likely theft, tampering and billing errors far faster than manual inspections. Transformer and feeder health models predict failures from load and temperature patterns, so crews can intervene before outages. Forecasts also support renewable integration planning.

Customer-facing assistants can explain bills, report outages and guide new connection applications in local languages. Models need validation across seasons and regions, and decisions with financial consequences for consumers, such as theft penalties, require human verification on site. Explain model outputs to field staff in plain terms.

How we build for energy & utilities

Clear stages with a review at the end of each, so you always know what happens next and what it costs.

  1. 01

    Systems landscape review

    We document meters, SCADA, billing, GIS and data volumes.

  2. 02

    Data architecture

    We design time-series storage, validation rules and integration points.

  3. 03

    Field and consumer prototypes

    Crew and consumer screens are tested in real working conditions.

  4. 04

    Incremental build

    Modules ship in sprints, starting with the highest-impact use case.

  5. 05

    Rollout and operations support

    We deploy by circle or region and support operations after launch.

Energy & Utilities use cases

  1. Prepaid smart meter recharge app

    Consumers see daily consumption and balance, recharge through UPI in seconds, receive low-balance alerts before disconnection and understand tariffs, while the utility reduces collection effort, field visits and billing disputes.

  2. Transformer health monitoring

    Sensors and meter data track load and temperature on distribution transformers, dashboards flag overloaded units and models predict failures, helping engineers plan upgrades and replacements before outages hit homes and businesses in the area.

  3. Rooftop solar installer CRM

    An installer manages leads, site surveys, quotations, subsidy and net metering applications and installation tasks in one system, with customers tracking each step instead of calling for updates on approvals.

  4. Energy dashboard for commercial users

    Factories and commercial buildings see consumption by time of day, demand peaks and power factor, receive alerts before exceeding contract demand and compare sites, cutting penalties and identifying savings opportunities.

  5. Public outage map

    Consumers see current outages and estimated restoration times on a map and receive updates by SMS or WhatsApp, reducing call center volume during storms and building trust through honest, timely transparency.

Energy & Utilities software FAQs

Something else on your mind? Ask a consultant and get a reply within one business day.

What drives the cost of utility software?

Cost depends on the number of meters or assets, data frequency, integrations with billing, SCADA and GIS systems, field app scope and hosting requirements. We scope it with you in a free consultation, then share a fixed quote.

Can you integrate with existing SCADA and billing systems?

Yes, through supported interfaces such as APIs, database views, file exchange or standard protocols. We do not replace control systems; we read from them safely.

Can the field app work in areas without network?

Yes. Field apps store work orders, photos and readings offline and sync automatically when connectivity returns.

Do you build software for rooftop solar companies?

Yes. We build lead management, site survey, installation tracking and generation monitoring apps for rooftop solar installers.

How long does a utility software project take?

A focused consumer app or solar monitoring dashboard takes 10-14 weeks. Meter data platforms with several integrations are delivered in phases.

Do you work with DLMS smart meter data?

Yes. We integrate with head-end and meter data management systems that collect DLMS/COSEM data, process interval readings, events and alarms, and build analytics, billing and consumer-facing features on top, while respecting the security requirements of metering infrastructure.

Can consumers recharge prepaid meters through an app?

Yes. A consumer app can show live balance and consumption, accept payments through UPI, cards and wallets, and pass recharge credits to the billing or meter data system immediately, with receipts and low-balance notifications sent automatically.

We work with clients across the USA, UK, Australia, UAE, New Zealand and India.
