Ellume vs Prescinto: Beyond Finding the Root Cause
Ellume and Prescinto both monitor solar, wind and battery storage, find the causes of underperformance and turn them into maintenance work. The difference is depth. Ellume Vector validates every alert against physics, accounts for every lost megawatt-hour by measured cause and prices it at your tariff, and forecasts generation with a confidence range. Ellume Bridge adds context-aware NERC GADS classification with human review before filing. If those are your hardest problems, that is the difference to weigh.
Both Ellume and Prescinto help operators of solar, wind and battery storage assets see how their plants are performing, find the causes of underperformance and turn them into maintenance work. Prescinto, acquired by IBM in 2024 and now offered as IBM Maximo Renewables, is an AI-driven asset performance management platform that works across equipment vendors. Ellume offers Ellume360™ (SOLAR360, WIND360, BATTERY360), with two engines built into it: Vector™ for diagnostics and forecasting, and Bridge™ for NERC GADS compliance. So this is not a question of whether you get root-cause analysis. It is a question of how far each platform takes you once a loss appears: how far you can trust the finding, how precisely it is costed, and what comes next.
Finding the cause of a loss is half the job. The other half is trusting the alert, costing the fix and knowing what tomorrow will bring.
Who should choose which
Both platforms monitor solar, wind and storage across equipment vendors, identify causes of underperformance and turn them into maintenance work. If that is all you need, either platform provides it. If you also need alerts validated against physics, every loss priced at your tariff, generation forecasts you can commit against, or context-aware NERC GADS reporting, that is where Ellume is built to go further.
What each platform does
Prescinto. An AI-driven asset performance management platform for solar, wind and battery storage. It collects plant data from different equipment vendors, identifies causes of underperformance, breaks down losses and suggests maintenance work orders, now within IBM's Maximo suite. Ellume. Ellume360 covers performance management across solar, wind and battery storage, commercial management, and field service with ticketing. Built into it, Ellume Vector combines physics-based checks with machine learning tuned to each plant's own normal for diagnostics and forecasting, and Ellume Bridge automates NERC GADS reporting.
Where Ellume goes deeper
Both platforms find root causes, break down losses, clean data and support GADS reporting. Ellume goes further on each.
Vector: root cause, validated by physics
Both platforms identify the causes of underperformance. Vector also validates every alert against the physics of the asset and recognises cloud, soiling, low wind, temperature and grid events for what they are, so they never become false fault tickets, cutting false alarms by 90%.
Vector: loss analysis, priced at your tariff
Both platforms break down where energy is lost. Vector builds that breakdown from measurements only, attributes each loss to the fault that caused it, prices it at the plant's own tariff, and shows any unexplained residual openly.
Vector: data you can trust
Both platforms clean incoming data. Vector also names the specific errors that make healthy-looking data wrong (frozen sensors, meter misconfiguration, duplicated channels, drifting sensors, timestamp errors) and says so when data is too poor to judge.
Bridge: context-aware NERC GADS
Both platforms support NERC GADS reporting. Bridge classifies each event into the correct cause code using the plant's own data, weather and operating context, telling a forced outage apart from a resource-unavailable event, routes every report through human review, and automates filing, cutting reporting time by 80%.
What Ellume adds
Vector: forecasts you can commit against. Physics-based forecasts for each asset, built from degradation, turbine power curves, inverter clipping and soiling, with a calibrated P10–P90 range. Accuracy is tracked against each site's actual output, and one forecast drives both the grid schedule and the O&M plan. Ellume360: commercial management. Commercial management sits in the same platform as performance management and field service.

One fleet, one month: an illustrative case
Numbers illustrative. A mixed portfolio is running a few per cent under budget. First, Ellume Vector flags that one site's reference sensor has drifted, so part of the apparent shortfall was never real. Of what remains, Vector attributes each loss to a measured cause and prices it at the plant's tariff: a turbine running with yaw misalignment, a solar string producing nothing while its neighbours generate, a battery cell anomaly affecting state of health. Passing cloud and a grid outage are recognised as outside the plant's control, so nobody is sent to site. Ellume Bridge classifies the turbine outage into the correct NERC cause code using plant data and weather — a forced outage, not low wind — and holds it for review. And Vector's forecast for tomorrow already reflects the yaw fix and the dead string, with a P10–P90 range to bid against.
A decision rule you can apply today
Both platforms cover monitoring, root-cause analysis and maintenance work across mixed fleets. If you need every alert validated against physics, every loss priced at your tariff, and forecasts with a range you can schedule against, choose Ellume Vector. If you need NERC GADS reporting that is context-aware and human-reviewed, choose Ellume Bridge.
Frequently asked questions
- Is Prescinto still available as a separate product?
- Prescinto was acquired by IBM in October 2024 and is now offered as IBM Maximo Renewables, part of IBM's Maximo Application Suite.
- Does Ellume cover the full operations workflow, or only diagnostics?
- Ellume360 covers performance management, commercial management, and field service with ticketing across solar, wind and battery storage. Vector (diagnostics and forecasting) and Bridge (NERC GADS compliance) are built into the same platform.
- How does Ellume Vector tell a real fault from the weather?
- Vector recognises cloud, soiling, low wind, temperature and grid events for what they are, so they are not raised as faults, and validates every remaining alert against physics before it reaches your team.
- How is Ellume Vector's forecasting different?
- Forecasts are built from the physics of each specific asset rather than a regional weather feed, carry a calibrated P10–P90 range, are checked against each site's actual output, and drive both the grid schedule and the O&M plan.
