The U.S. energy grid operates with an average infrastructure age of 30+ years, yet utilities must now integrate renewable sources, manage distributed generation, and respond to real-time demand fluctuations—all while maintaining 99.95% uptime requirements. According to the American Public Power Association, electric utilities alone manage over 5.5 million miles of distribution lines and serve 158 million customers, creating data management challenges that legacy systems simply cannot address.
Energy and utilities companies face a unique software challenge: mission-critical systems that cannot go offline, regulatory compliance requirements that change annually, and customer expectations for real-time data access. When a natural gas utility's SCADA system was built in 1997, it didn't need to communicate with smart meters, mobile field service apps, or predictive maintenance algorithms. Today, that same utility needs all three integrated seamlessly while maintaining perfect operational continuity.
FreedomDev has spent over two decades building [custom software development](/services/custom-software-development) solutions for companies managing critical infrastructure. We've integrated legacy SCADA systems with modern IoT platforms, built real-time monitoring dashboards that process 50,000+ sensor readings per minute, and developed billing engines that handle complex rate structures including time-of-use pricing and net metering calculations for solar customers.
The complexity in utility software isn't just technical—it's operational. A water utility serving 200,000 customers might operate 15 pump stations, 8 treatment facilities, and 2,000 miles of distribution mains. Their software must coordinate maintenance schedules, track water quality measurements every 15 minutes, manage emergency response protocols, and generate regulatory compliance reports—all while technicians work in areas without reliable cellular coverage.
Our approach focuses on incremental modernization rather than risky 'rip and replace' projects. We've helped utilities build integration layers that connect 20-year-old SCADA systems to modern analytics platforms without interrupting operations. One municipal electric utility we worked with needed to integrate data from three separate systems: a 1990s-era outage management system, a GIS database, and a new AMI (Advanced Metering Infrastructure) network. We built middleware that harmonized data formats and provided a unified API, reducing their average outage response time by 34%.
Energy companies also struggle with the 'edge computing' challenge. Wind farms, solar installations, and pipeline monitoring stations generate massive data volumes in remote locations. A single wind turbine produces 30-50 GB of operational data annually, and large wind farms operate 100+ turbines. Our [systems integration](/services/systems-integration) work includes edge data processing solutions that analyze sensor data locally, transmitting only actionable insights to central systems—reducing bandwidth costs by 78% for one renewable energy operator.
Regulatory compliance adds another layer of complexity. NERC CIP (Critical Infrastructure Protection) standards, FERC reporting requirements, state-level renewable portfolio standards, and environmental monitoring obligations create a compliance matrix that changes constantly. We've built compliance management systems that automatically generate required reports, track certification expirations, and maintain audit trails—capabilities that proved essential when one utility client faced an unexpected regulatory audit with 30 days' notice.
The utility industry's workforce challenge directly impacts software needs. With 25% of utility workers eligible for retirement in the next five years (according to the U.S. Bureau of Labor Statistics), companies must capture institutional knowledge and create systems that newer, tech-savvy workers expect. We've developed knowledge management platforms that combine legacy documentation with modern search, mobile access, and video training modules—helping utilities preserve decades of operational expertise while attracting younger talent.
Asset management represents a critical software need across all utility segments. A typical electric utility manages 100,000+ assets (transformers, poles, switches, meters) with varying maintenance schedules, expected lifespans, and failure consequences. We've built asset management systems integrated with GIS data, maintenance history, and predictive analytics that help utilities prioritize capital spending. One client identified $2.3M in deferrable replacements in the first year by analyzing actual asset condition rather than following fixed replacement schedules.
Customer expectations have transformed utility software requirements. Residential customers expect mobile apps showing real-time usage, outage notifications, and paperless billing. Commercial customers need detailed interval data, demand response integration, and carbon reporting. Industrial customers require power quality monitoring and load forecasting. Our customer portal implementations handle these diverse requirements while integrating with legacy CIS (Customer Information Systems) and billing platforms—often built on mainframe systems that predate the internet but cannot be replaced due to their embedded business logic and regulatory approval history.
We specialize in building custom software for your industry. Tell us what you're dealing with.
Utilities operate SCADA systems averaging 15-20 years old, built on proprietary protocols like Modbus, DNP3, and IEC 60870. These systems control critical infrastructure but can't natively communicate with modern IoT sensors, cloud analytics platforms, or mobile applications. Direct replacement risks operational disruptions in systems that must maintain 24/7/365 uptime. We've encountered electric utilities running SCADA systems on Windows XP (no longer supported) because the vendor-specific software won't run on modern operating systems. The challenge involves building secure integration layers that translate between protocols while maintaining microsecond response times for control operations and implementing cybersecurity measures that meet NERC CIP standards without degrading system performance.
A typical utility operates 8-12 separate systems: CIS for billing, GIS for asset locations, OMS for outage management, SCADA for operations, EAM for maintenance, and more. Each system stores critical data in different formats, often without unique identifiers that span systems. One water utility we audited had customer account numbers that didn't match between their billing system and GIS database, making it impossible to automatically locate customers reporting service issues. These silos prevent comprehensive analytics, slow emergency response, and create data quality problems. Our [database services](/services/database-services) work often begins with data archaeology—mapping relationships between systems that were never designed to communicate and building master data management strategies that establish single sources of truth.
Advanced Metering Infrastructure (AMI) networks generate data at unprecedented volumes. A utility serving 250,000 customers with 15-minute interval meters receives 35 million readings daily. Add SCADA sensor data (updated every 2-4 seconds), power quality monitors, and distribution automation devices, and data volumes explode. This data must be processed in real-time to detect anomalies, identify theft, validate meter accuracy, forecast demand, and trigger automated responses. We've worked with utilities where a single substation generates 180,000 data points daily from voltage monitors, current transformers, and environmental sensors. Traditional database architectures fail under these loads. Solutions require time-series databases, stream processing frameworks, and edge computing strategies that filter noise before transmission.
Utility field operations occur in remote areas, underground vaults, and rural locations where cellular coverage is unreliable or nonexistent. Technicians need access to asset information, work orders, safety procedures, and real-time system status—but can't depend on constant connectivity. One natural gas utility we worked with had technicians driving 45 minutes back to the office to upload completed work orders because their mobile app required continuous internet access. Effective field solutions require offline-first architecture, local data caching, conflict resolution for data modified offline, and intelligent sync strategies. The complexity increases with safety-critical information: a technician working on high-voltage equipment needs absolutely current switching orders and clearances, not cached data from 3 hours ago.
Utility billing has evolved far beyond simple commodity charges. Modern rate structures include time-of-use pricing, demand charges, seasonal variations, tiered consumption rates, net metering for solar customers, demand response credits, low-income assistance programs, and regulatory cost recovery mechanisms. A single commercial customer might have a rate schedule with 20+ variables. We've encountered electric cooperatives with 40 different rate codes serving various customer classes. Billing systems must handle proration for mid-month rate changes, back-billing for meter failures, and complex validation rules. One utility discovered their billing system had been undercharging large commercial customers for 18 months due to demand calculation errors—a $780,000 revenue loss. [ERP development](/services/erp-development) for utilities requires deep understanding of rate design and regulatory accounting.
Energy utilities face overlapping compliance requirements from FERC, state public utility commissions, EPA, OSHA, and industry standards bodies like NERC. Each regulator demands different reports, data retention periods, and audit capabilities. NERC CIP standards alone include 45+ requirements for cybersecurity, physical security, and operational controls. Compliance isn't just reporting—it requires demonstrable processes, change tracking, and evidence preservation. When one utility client faced a CIP audit, auditors requested proof of every access control change made in the previous 36 months. Their manual logs were incomplete and contradictory. We've built compliance management systems that automatically capture changes, correlate events across systems, and generate audit-ready reports. The challenge intensifies because compliance requirements change—sometimes with 90 days' notice—requiring flexible systems that can adapt to new reporting needs.
Utilities manage capital-intensive assets with 30-50 year lifespans: transformers, underground cables, pumps, and turbines. Asset failures cause service interruptions, emergency repair costs, and safety risks. Traditional time-based maintenance (inspect every X months) wastes resources on healthy assets while missing early failure indicators on stressed equipment. Predictive maintenance requires integrating multiple data sources: thermal imaging, vibration sensors, partial discharge monitoring, loading history, and environmental conditions. One electric utility we worked with had 8,000 distribution transformers with known high-failure models but lacked a system to prioritize replacements based on actual condition and consequence of failure. We built an asset health scoring system that integrated GIS data, loading patterns, maintenance history, and sensor readings—helping them prioritize $12M in replacement spending to address highest-risk assets first.
Energy infrastructure represents high-value targets for cyberattacks, ransomware, and nation-state actors. The 2021 Colonial Pipeline attack demonstrated real-world consequences. Utilities must secure operational technology (OT) networks that were never designed for security, often running on obsolete operating systems that can't be patched without vendor support. They need air-gapped networks for critical SCADA systems, but still require data from those systems for business analytics. Security solutions must not introduce latency that degrades real-time control performance. We've implemented secure data diodes that allow one-way data extraction from SCADA networks, intrusion detection systems tuned for industrial protocols, and zero-trust architectures for field device management. The challenge includes user behavior: technicians who need emergency access to locked-down systems, vendors requiring remote access for troubleshooting, and executives wanting operational dashboards on mobile devices.
FreedomDev's integration work connected our 20-year-old SCADA system to modern mobile apps without disrupting operations. Field crews now have real-time system status on tablets, reducing our emergency response time by 34%. Their team understood both the technical challenges and operational realities of utility work.
We build protocol translation and integration middleware that connects legacy SCADA systems to modern applications without modifying the operational core. For one municipal electric utility, we developed an integration layer that reads data from their DNP3-based SCADA system (installed 1998) and exposes it via REST APIs for their new outage management system and mobile apps. The middleware handles protocol conversion, data validation, and buffering—maintaining 2.3-second average latency while processing 4,200 data points per minute. This approach preserved their $1.8M investment in existing SCADA infrastructure while enabling modern applications. We implement similar solutions using OPC-UA, MQTT, and Apache Kafka depending on requirements. The architecture includes redundancy and failover capabilities that match utility uptime requirements, with automatic switchover tested quarterly.
Our [systems integration](/services/systems-integration) approach for utilities begins with master data management—establishing authoritative data sources and synchronization rules across fragmented systems. For a water utility operating six separate systems, we implemented an MDM platform with bidirectional integration that maintains consistent customer accounts, asset identifiers, and location data. The system includes data quality rules (address validation, duplicate detection), workflow for exception handling, and audit trails showing data lineage. Within 8 months, they achieved 97% address match rate between billing and GIS systems (up from 64%) and reduced duplicate customer records by 89%. The MDM platform became the integration hub for a new mobile app, customer portal, and business intelligence system. We establish data stewardship roles, documentation standards, and governance processes that ensure data quality improvements persist after implementation.
We architect high-volume data processing pipelines using technologies like Apache Kafka, Apache Flink, and time-series databases optimized for utility data patterns. For an electric cooperative with 180,000 smart meters generating 15-minute interval data, we built a stream processing pipeline that ingests 17 million readings daily, validates data quality, detects anomalies, calculates derived metrics, and triggers alerts—all with sub-5-minute latency. The system identified 380 malfunctioning meters in the first month (meters reporting impossible consumption values) and detected 23 cases of probable electricity theft based on usage pattern changes. Edge computing components pre-process data at substations, filtering noise and calculating local statistics before transmission. This reduced central system data volumes by 71% while maintaining full granularity for exception analysis. The architecture scales horizontally, adding processing capacity as meter deployments expand.
Our mobile solutions for utility field operations use offline-first architecture with intelligent synchronization. We developed a field service app for a natural gas utility with 45 field technicians working in rural areas with spotty coverage. The app caches work orders, asset information, safety procedures, and relevant GIS map tiles when connected. Technicians complete inspections, capture photos, update asset conditions, and record time/materials offline. The app queues changes locally and syncs automatically when connectivity returns, with conflict resolution rules for data modified on both server and device. GPS tracking continues offline, uploading location history when connected—providing accurate time-on-site records for billing and productivity analysis. The solution reduced average work order completion time from 2.3 days to 4.7 hours by eliminating return trips to the office. Similar architecture powers our inspection applications for electric utilities doing pole assessments and vegetation management surveys, as demonstrated in our [Real-Time Fleet Management Platform](/case-studies/great-lakes-fleet) case study which handled offline operations in marine environments.
We develop custom billing calculation engines that handle utility-specific rate complexity while maintaining accuracy and audit trails. For an electric utility transitioning to time-of-use rates, we built a billing engine that processes interval data (96 data points per customer per day), applies rate schedules with 6 time-of-use periods, calculates demand charges using 15-minute rolling windows, and handles net metering for 2,400 solar customers. The system includes validation rules that flag anomalies before bill production and detailed calculation breakdowns for customer service. It supports shadow billing (running new rates in parallel with old for customer comparison) and what-if scenarios for rate design analysis. Integration with their existing CIS follows patterns similar to our [QuickBooks Bi-Directional Sync](/case-studies/lakeshore-quickbooks) implementation—maintaining data consistency while preserving legacy system investment. The engine reduced billing error disputes by 67% through improved calculation transparency and validation.
We build compliance management platforms that consolidate regulatory requirements, automate data collection, and generate audit-ready reports. For a regional electric transmission operator facing NERC CIP compliance, we developed a system that tracks 180+ discrete compliance requirements across 14 substations. The platform automatically collects evidence from network security systems, physical access controls, and change management systems—correlating events to demonstrate compliance. Automated workflows ensure timely completion of required tasks (security patch application, background checks, training completion) with escalation for overdue items. The system reduced compliance administration time by 43% and provided real-time compliance posture visibility. Similar approaches work for EPA emissions reporting, state renewable portfolio standard tracking, and water quality compliance. Flexible report builders adapt to changing regulatory requirements without software modifications, using templated data extraction and formatting rules.
Our asset health monitoring solutions integrate diverse data sources—sensor readings, maintenance history, loading patterns, environmental conditions, and asset attributes—to predict failures and prioritize investments. For an electric utility with 12,000 distribution transformers, we built a predictive model that scores asset health (0-100) based on age, loading history, maintenance records, oil quality tests, and failure history of similar units. The model identifies high-risk transformers for proactive replacement, optimizing capital spending. In the first 18 months, the utility prevented 14 predicted transformer failures through proactive replacement, avoiding an estimated $340,000 in emergency repair costs and outage impacts. The platform includes cost-benefit analysis tools that weigh replacement costs against failure consequences (outage duration, affected customers, secondary damage risk). Machine learning models improve continuously as actual failure data refines predictions. Similar approaches apply to pump stations, underground cables, and valve management.
We design and implement secure architectures that enable data flow from operational technology (OT) networks while maintaining critical system security. Our approach uses unidirectional data gateways, DMZ architectures, and protocol-aware firewalls that understand industrial control system communications. For a natural gas pipeline operator, we implemented a secure data extraction architecture using data diodes—hardware-enforced one-way communication devices that prevent any inbound traffic to SCADA networks. Business systems access pipeline data through historian servers in a DMZ zone, providing real-time visibility without compromising control system security. The architecture meets NERC CIP requirements and passed third-party security audits. We implement network segmentation, least-privilege access controls, and continuous monitoring for industrial networks. Role-based access with multi-factor authentication ensures field technicians, control room operators, and business users have appropriate access levels. Similar security approaches enabled vendor remote access with session recording and automated disconnect for inactive connections.
