Energy-efficient software
At Helmes, we consider energy and resource efficiency when designing software architecture, processing data and managing infrastructure. Efficient code, optimised computing resources and avoiding unnecessary complexity can reduce energy consumption and operating costs.
In Helmes Group projects, infrastructure improvements have achieved up to 60% lower energy consumption, demonstrating the practical value of sustainable software architecture for both environmental and operational efficiency.
Our work in the energy & utility sector
Digital twin for building energy performance
Helmes developed a digital twin application for SBLC that combines building information, electricity and gas consumption data, and energy performance calculations. Covering buildings across the Netherlands, the solution helps municipalities and property owners assess energy efficiency, estimate renovation costs and plan investments.
- Covers all NL buildings
- Calculates renovation costs
Utility consumption data for smarter resource planning
Helmes developed a central data warehouse for Mainor Ülemiste, integrating electricity, gas, heating and water consumption data across the Baltics’ largest business campus. Automated daily data collection and consumption analysis provide a reliable foundation for monitoring resource use and supporting data-driven planning.
- 18K+ campus users
- ~400 companies
Automating GHG emissions calculations and reporting
Helmes developed an Azure Databricks solution for an international financial institution, automating greenhouse gas emissions calculations and reporting across loan and investment portfolios. The platform integrates multiple data sources and supports PCAF-aligned carbon accounting, demonstrating expertise in emissions data management and automated sustainability reporting.
- 55% faster – API calls
- Fully automated – GHG emissions reporting
AI projects forecast to deliver ROI within 12 months
Identifying valuable AI opportunities in energy
Only 43% of AI projects initiated by surveyed energy and utilities organisations were expected to deliver a return within 12 months. Helmes helps energy companies evaluate where AI could create business value through its AI Value Scan service, assessing data readiness, identifying practical use cases and prioritising investments before development.
Developing Estonia’s electricity and gas market systems
Through more than five years of cooperation with Elering, Estonia’s electricity and gas transmission system operator, Helmes developed software solutions supporting the country’s energy infrastructure and market operations.
Electricity and gas data hub
Helmes built a centralised data exchange platform for Estonia’s electricity and gas markets, connecting consumers, energy sellers and network operators. The system provides shared access to historical and current consumption data, streamlining information exchange and ensuring transparent, equal access for market participants.
Renewable energy information system
To support renewable energy production and subsidy management, Helmes developed an information system that manages renewable electricity and gas production data, including energy sold back to the network. It also calculates producer subsidies in accordance with Estonia’s Electricity Market Act, supporting the administration of renewable energy support schemes.
Digital self-service portal
Helmes developed a digital portal for Elering’s network customers, landowners and contractors. Customers can access invoices, contracts and consumption data, while landowners manage compensation applications and agreements. Contractors use shared planning and work management tools. Bringing these services together simplifies communication and daily operations.
Metering data management
Electricity and gas metering data management systems collect readings from automated meters and other sources, associate consumption data with customers and transfer information to connected systems in the required formats. Developed by Helmes, these solutions provide a structured foundation for processing metering information and exchanging data between energy market systems.
electric utilities reporting additional use cases from data investments
Making more of energy data
93% of surveyed electricity utilities reported that investments in data and intelligence enabled additional use cases beyond their original purpose. With over a decade of experience in data analytics and business intelligence, Helmes helps energy and utility organisations integrate data from multiple systems, improve reporting and identify new opportunities to use existing information.
