Energy and Cleantech Software Development Services for US & EU Utilities, ESCOs and Renewables

YuSMP Group builds energy and cleantech software for US utilities and ESCOs, EU DSOs and TSOs, renewable IPPs and EV charging operators, plus corporate ESG and sustainability teams reporting under CSRD. Senior engineers deliver DERMS and VPP platforms, OCPP-compliant EV charging back-ends, smart-meter ingestion pipelines, carbon accounting under the GHG Protocol, renewable-asset monitoring, and demand-response platforms. Work runs under NERC CIP, FERC orders, NIS2, IEC 61850, OCPP, OpenADR and CSRD ESRS E1 disclosures.

Energy and cleantech software development for US and EU utilities

Our energy and cleantech practice serves four buyer profiles: investor-owned and municipal utilities modernizing grid edge, DERMS and customer experience under FERC Order 2222 and NERC CIP; EU DSOs and TSOs implementing Clean Energy Package directives, NIS2 obligations and IEC 61850 substation automation; EV charging operators and CPOs building OCPP back-ends, OCPI roaming and ISO 15118 Plug & Charge; and renewable IPPs, ESCOs and corporate ESG teams reporting energy intensity, Scope 1-3 emissions and EU Taxonomy alignment. We treat OT/IT segregation, FERC order compliance and CSRD audit trails as engineering inputs. Explore how we deliver this through our Custom Software Development service. Operator and field-crew tools ship through our mobile app development team — see our climate-control IoT app for connected-device energy control.

Challenges

Energy & cleantech challenges we solve

OT/IT convergence & grid-edge security

DERs, smart meters and field controllers erode the old air gap. We engineer NERC CIP electronic security perimeters and IEC 62443 zones-and-conduits into applications that must cross the OT/IT boundary — validated by penetration testing & security audits.

DER orchestration at scale

Rooftop solar, batteries, EVs and flexible load must be aggregated and dispatched under FERC Order 2222, IEEE 2030.5 and DERMS logic — with sub-second telemetry and forecasting, not spreadsheet estimates.

Legacy + modern protocol sprawl

A single utility runs IEC 61850 substations next to DNP3, IEC 60870-5-104, Modbus and CIM/MultiSpeak. We bridge them into one data model instead of forcing a rip-and-replace.

Smart-meter data at volume

Interval data from hundreds of thousands of meters has to be ingested, normalized and reconciled for revenue protection and load forecasting — AMI head-end and MDM integration, not batch CSV.

Regulatory & disclosure load

NERC CIP, FERC orders, EU NIS2 essential-entity duties and CSRD / ESRS E1 climate disclosure all land on the same platform. We treat them as engineering inputs with audit-grade data lineage from day one.

EV charging interoperability & roaming

Charge-point fleets must speak OCPP to the back-end, OCPI/OICP to roaming hubs and ISO 15118 Plug & Charge to vehicles — while tariffs, billing and settlement stay consistent across networks.

FAQ

Energy & Cleantech FAQ

How do you handle NERC CIP for US bulk-power systems?

We design control-system-adjacent applications against NERC CIP-002 through CIP-014, including BES Cyber System identification, electronic-security-perimeter controls, configuration change management and CIP-013 supply-chain risk requirements.

Do you integrate with IEC 61850 substations?

Yes. We integrate with IEC 61850 IEDs via MMS, GOOSE and Sampled Values, and bridge IEC 60870-5-104 and DNP3 SCADA where modern equipment is not deployed. ICCP (TASE.2) for control-center exchanges.

Can you build OCPP-compliant EV charging platforms?

Yes. We deliver OCPP 1.6J and 2.0.1 charge-point management systems, OCPI 2.2.1 roaming hubs, ISO 15118 Plug & Charge readiness and operator-facing pricing, billing and reservation flows.

How do you cover NIS2 for EU energy entities?

Energy is a NIS2 essential sector. We engineer risk management, incident reporting (24h early warning / 72h notification / 1-month final report), supply-chain due diligence and board-accountability artefacts into the platform from day one.

Do you build carbon accounting under CSRD and the GHG Protocol?

Yes. We build Scope 1, 2 and 3 data pipelines under GHG Protocol Corporate Standard, mapped to ESRS E1 disclosure requirements with audit-grade data lineage and EU Taxonomy DNSH evidence.

What about demand response and OpenADR?

We deliver VTN and VEN implementations under OpenADR 2.0b / 3.0, aggregator portals, baseline calculation, ISO/RTO market settlement integrations (CAISO, PJM, ERCOT) and EU TSO ancillary-service participation.

What technology stack do you use for energy and cleantech platforms?

Backend on Python (FastAPI) and Node.js/TypeScript, with Java/Spring where an existing utility platform requires it. Data on Kafka and MQTT for ingestion, TimescaleDB/InfluxDB and Apache Iceberg for time-series, and PostgreSQL/PostGIS for asset and geospatial models. Frontends on React/Next.js, deployed on AWS or Azure (plus sovereign-cloud and on-prem for OT-adjacent workloads) via Kubernetes and Terraform. We deliberately favour a well-supported, maintainable stack for decade-long grid software.

Can you modernize legacy grid systems without a full rip-and-replace?

Yes — that is the norm. A single utility typically runs IEC 61850 substations alongside DNP3, IEC 60870-5-104, Modbus and CIM/MultiSpeak. We bridge those protocols into one canonical data model and add a modern application and API layer on top, so you modernize incrementally and keep operating the existing SCADA, GIS, CIS and historian estate rather than replacing it in one high-risk cutover.

How do you forecast DER output, load and market prices?

We build load, DER-output and price-forecasting models on Python ML tooling with proper MLOps — weather-driven PV and wind forecasts, load prediction for demand-response baselines, and price signals for VPP dispatch and market bidding. Models carry audit-ready lineage so forecasts used in settlement and ESG reporting can be explained and reproduced, not treated as a black box.

How do you handle smart-meter and customer-energy data privacy?

Interval and customer-energy data is sensitive personal data. We engineer GDPR (EU) and CCPA/CPRA (US) controls into ingestion and access — data minimisation, purpose limitation, consent tracking and role-based access — and support Green Button (Download / Connect My Data) for customer-authorised sharing. Data lineage and retention rules are built in so meter data used for billing, forecasting and disclosure stays governed end to end.

What engagement models and team structures do you offer?

Fixed-scope delivery for well-defined modules (an OCPP back-end, a CSRD data pipeline), time-and-materials for evolving grid-edge work, and a dedicated development team for multi-year platform programmes. Teams pair senior engineers with grid, market and ESG domain leads, and we can integrate with your internal OT, IT and compliance functions rather than working as a detached vendor.

Do you provide 24/7 support and CIP-aware change management after launch?

Yes. We run phased deployments with operator training, 24/7 grid-aware on-call, and change control aligned to NERC CIP configuration-management and CIP-013 supply-chain requirements. For EU essential entities we support annual NIS2 and CSRD assurance cycles, so post-launch operations, patching and audits stay inside the same compliance envelope the platform was built to.
