BESS Operations Intelligence Report | Delfos Energy
A benchmark report on BESS performance, degradation, curtailment and revenue optimization, built from operator interviews, IEA and BNEF data.
PERFORMANCE ENGINEERING
Performance Engineering as a Service for Renewable Energy Portfolios
Root cause analysis, custom predictive models and a direct line to the team that builds them, on top of the Delfos platform.
A dedicated team of performance engineers working inside your data, not just delivering a dashboard, to turn alarms into root causes and root causes into a maintenance plan.

An Alert Is Not a Root Cause
Mid to large renewable operators typically manage:
Multiple SCADA systems and OEM platforms across the portfolio
More sites, more OEMs, more signals as the fleet scales
Alarm fatigue and fragmented context between monitoring and maintenance teams
Mid to large renewable operators typically experience:
Very slow support that impacts the business
Slow response and lengthy development cycles for requested improvements
Providers who don't take feedback
The solution
Look for a Partner, Not Just a Vendor
Once implementation is done, most operators are not looking for another tool. They are looking for a partner who stays involved after go live and helps them build the next thing, not just maintain the last one
"Delfos treated us like partners from day one. Their team feels like an extension of ours." — Finlight, Solar client
"Delfos has strong know how, a fast platform, quick responses, and a very eager team." — Dost Enerji, Wind client
Root Cause Investigation
Automated failure analyses include:
Root cause identification through temporal and spatial pattern analysis across neighboring turbines
Deviation detection comparing predicted versus actual behavior on key turbine variables
Ranking of main failure drivers by duration and revenue impact
Impact: clients avoided 224 wind turbine shutdowns using predictive anomaly detection
Custom Predictive Models
Our engineering team builds and tunes models specific to your fleet:
Over 100 predictive models running across wind, solar, hydro and BESS
10+ wind turbine manufacturers integrated
Models evolve over time and can accommodate new failure modes as they appear
Impact: early detection on a yaw system fault avoided the loss of 7,778 MWh over 299 days on one turbine
Benchmarking Against P50
Performance engineering includes:
Identifying which loss categories are deviating from the P50 expectation
Power curve and subsystem analysis, including pitch, generator and oil, to detect underperformance
KPI reporting aligned to IEC methodology for globally consistent numbers
Impact: downtime fall from 9 to 12 % down to 1 to 2 %
Dedicated Engineering Support
What comes with the service:
A named engineering contact, not a ticket queue
Feedback from your team feeds directly into model tuning and roadmap requests
Support scoped for both EU and US/LATAM operating hours
Impact: 20 to 30 % reduction in invoicing workload and 10 % revenue recovery from previously hidden energy losses
WHY IT MATTERS AT SCALE
As fleets scale, alarms multiply. Insight does not, unless someone is engineering it.
More sites, more OEMs
More signals, more noise
Alarm fatigue sets in
Insight needs engineering
