Modular, fixed-scope engagements that de-risk your platform decisions and accelerate time-to-market. No 18-month waterfalls. No vendor lock-in.
Platform Architecture Validation
2 weeks | £15k-25k
Before committing £50k-200k to an ETRM implementation, get external validation. We evaluate platform options, design team structure, create phased roadmaps, and identify hidden risks. "Builder's Blind Spot" insurance for critical decisions.
Deliverable: Platform evaluation matrix, recommended architecture, team structure, implementation roadmap, risk assessment
Exchange Connectivity & Integration
Modular | £15k-40k per integration
EPEX SPOT, ICE, EEX connectivity. Order submission, trade capture, deal flow integration. Built modularly—start with one market, expand incrementally. De-risked by our Limejump EPEX implementation.
Deliverable: Exchange API integration, order management module, trade capture system, internal system connectivity
Bespoke Risk Management Systems
Per module | £15k-40k
Position monitoring, P&L calculation, exposure reporting, VaR engines, compliance dashboards. Custom to your portfolio structure. Individual tools, not full ETRM replacement.
Typical modules: Position aggregation engine, mark-to-market P&L, delta ladder reporting, stress testing, regulatory compliance
Centralized Data Infrastructure
4-8 weeks | £25k-80k
Multi-source data aggregation (market data, trades, positions), unified data model, API layer for downstream tools. Foundation for scalable trading operations.
Tech stack: Python, TimescaleDB/PostgreSQL, Kafka/event streaming, REST/GraphQL APIs, cloud-native deployment
Also Available:
Corporate Training & Team Bootcamps
4-6 weeks | £25k-50k. Custom team upskilling on energy trading fundamentals, ETRM architecture, Python for trading engineers.
Trading Desk Automation Sprint
2 weeks | Fixed scope. Rapid discovery, proof-of-concept, and implementation roadmap for day-ahead/intraday automation. Learn more
Example: GridSight Intelligence Platform
Proof-of-concept demonstrating our approach to building bespoke power trading software—from data ingestion to real-time analytics.
Real-Time Grid Intelligence & Historical Analysis
GridSight showcases our capability to build end-to-end trading platforms. It ingests data from Elexon BMRS and National Gas, processes it through high-performance pipelines (Python + TimescaleDB), and serves it via a web interface for strategic and tactical decision-making.
The Strategic View: Historical Analyser
Instantly answer: "What happened to prices the last time grid conditions were exactly like this?" Filter years of data to back-test scenarios in a single click.
The Tactical View: Live Plant Status
Answer: "What is every major asset doing right now?" Get a real-time "bingo board" of every power plant, including forward-looking bids, to see scarcity before it happens.
Visualise the Entire Grid in Real-Time
GridSight provides the macro and micro views you need. Track the real-time spare capacity of the entire CCGT fleet with the System Headroom View to gauge system tightness at a glance, or drill down into individual asset status on the Live Plant Status Board to understand the minute-by-minute dynamics.
We achieve this by engineering high-performance data pipelines that ingest and process information directly from primary industry sources like Elexon's BMRS and National Gas. The platform is built on a robust, scalable foundation of Python, Django, and TimescaleDB to deliver the speed and reliability your desk demands.
- Real-time generation output by fuel type.
- Forward-looking accepted bids and offers in the BM.
- Live status updates: generating, outage, or trip.
Built with Analytical Rigor & Modern Engineering
Beyond just writing code, we bring systematic thinking to energy trading software development. Our approach combines structured analysis frameworks with modern cloud-native architecture—turning complex market requirements into production-ready systems that traders actually want to use.
GridSight demonstrates this approach: combining real-time data ingestion with historical pattern matching to surface trading opportunities. We build similar analytical depth into every bespoke system we deliver.
