Wind · Solar · Battery storage

Find the lost megawatt-hours. Trust the numbers. Fix the cause.

Renewable Asset Partners helps owners and asset managers improve the performance of operating wind, solar and battery storage assets. We bring the engineering judgment and build the data, analytics and reporting behind it.

Questions asset managers ask every week

What is offline, since when, and what is left to do? What did we lose last month, and what caused it? What is our availability, and which definition is that?

One turbine, one month of 10-minute SCADA

Why it matters

Easy to ask. Slow to answer.

In many portfolios, answering the first one takes most of the morning meeting, and the team still isn't sure the answer is right.

What is down, since when, and why?

A turbine, inverter or battery block with no data can mean partial telemetry, a late backfill or a real outage nobody has diagnosed. Each needs a different response. Status logic sorts them before the morning review, so the review starts from a list of actions.

What did we lose, and what caused it?

Estimating lost MWh starts with a model of each asset's expected output: a power curve or neighboring turbine for wind, an irradiance model for solar, the dispatch schedule for storage. Different methods can disagree by several points of annual energy for the same event. We make the method explicit and apply it the same way each month.

What is our availability, and which definition?

Operations, lenders and the OEM each use a different definition, and all three can be right. Solar has the same problem with performance ratio, where different definitions give different values for the same plant. We calculate them all from the same event record, so when two numbers differ you can see why.

Technologies

Wind, solar and battery storage

Each technology fails, degrades and earns money differently. We measure each on its own terms, then report the portfolio on one basis.

Our fleet map shows all US wind, solar and battery plants of 5 MW or more (EIA data through Aug 2026).

Wind

Turbine availability, power-curve performance and component reliability, from 10-minute and high-resolution SCADA.

  • Availability per IEC 61400-26 and contract
  • Power-curve and yaw/pitch underperformance
  • Curtailment and derate classification
  • Gearbox, generator and blade reliability

Solar

Expected energy from irradiance, losses by cause, and the inverters and trackers that drive most of the downtime.

  • Performance ratio and expected energy
  • Inverter, combiner and tracker availability
  • Soiling, clipping and shading losses
  • Module degradation

Battery storage

Availability when dispatched, revenue lost to missed dispatch, and capacity fade and efficiency over time.

  • Capacity availability against dispatch schedules
  • Round-trip efficiency and auxiliary load
  • State of health and capacity fade
  • Market revenue, including ERCOT

What we do

The questions clients bring us

Some need a one-off answer. Others become a system your team runs every day. We do both.

We know we're losing energy. We can't say where, or how much it's worth.

Asset performance and operational analytics

Loss accounting from raw operational data: downtime, curtailment, derating, underperformance against the power curve or irradiance model, soiling, icing and missed dispatch, each separated and ranked by MWh and revenue so the fix list has an order.

Our availability number never matches the OEM's.

Performance reporting and KPI frameworks

KPI definitions for time-based, energy-based and contractual availability, calculated once and traceable to the events behind them. Monthly portfolio reporting and NERC GADS submissions that run without a spreadsheet relay. For portfolios spanning several owners or funds, the same definitions applied to every asset, so the numbers can be compared.

SCADA, work orders and market data sit in three systems that don't talk.

Data platforms and engineering

Pipelines, data models and quality checks built on Databricks or Microsoft Fabric, whichever fits the environment you already run. We design it, build it and hand it over documented.

We need a plan before we buy another tool.

Digital and data strategy

A review of the systems you have, from SCADA and plant controllers to CMMS, ERP and trading, with a target architecture, build-or-buy recommendations and a roadmap sized to your team. We sell no software, so the recommendation is ours alone.

We're acquiring a portfolio and want an independent read on how it really runs.

Technical and performance assessments

An independent assessment built from the operational data itself: production against budget, availability, loss categories, component reliability and the condition of the data you would inherit.

Our asset management team is stretched and needs senior help.

Support for renewable asset management teams

Support on warranty and availability claims, O&M strategy and supplier performance. We also train analysts to work with time-series plant data.

We're about to sign a turbine or O&M contract, or pick a software vendor, and want someone from the operator's side of the table.

Procurement and technology due diligence

Procurement strategy aligned with how the asset will be operated, RFP packages, vendor due diligence and delivery assurance, for turbine supply, service agreements and software.

Data

What goes in, what we configure, what comes out

The hard part is rarely the platform. It is knowing what a status code means, whether the met mast can be believed, and which availability definition the lender is reading.

Your systems

  • SCADA and historians 10-minute and high-resolution tags, alarms, status events
  • Plant controllers setpoints, curtailment and dispatch instructions, storage schedules
  • Battery management and EMS state of charge, state of health, alarms
  • EAM / CMMS work orders, maintenance campaigns, parts, warranty claims
  • ERP purchase orders, invoices, O&M cost by site
  • Market and trading prices, schedules, settlements
  • Weather met masts, irradiance sensors, reanalysis, forecasts
  • Contracts PPAs, service agreements, availability guarantees

What RAP configures

  • The platform Databricks, Microsoft Fabric and Azure, or the warehouse you already run
  • One asset model sites, devices, contracts and events that agree with each other
  • Status logic outage, curtailment or comms gap, with cause and owner
  • KPI definitions versioned and calculated once
  • Quality and coverage checks which numbers you can defend today, and which you can't yet

What your team gets

  • Down-assets list for the morning review classified before the meeting starts
  • Availability under each definition time-based, energy-based, contractual
  • Solar performance ratio one calculation method, applied consistently
  • Battery availability against dispatch by block, with the revenue effect of each shortfall
  • Loss accounting downtime, curtailment, derating, underperformance
  • Reliability by component failure rates, OEM benchmarking
  • O&M cost tracking by site, campaign and supplier
  • NERC GADS reporting
  • Portfolio, lender and investor reports
  • Governed tables analysts can query directly

Systems we have integrated include SAP, IBM Maximo and other maintenance systems, ERCOT MIS, cloud SCADA platforms, turbine OEM data portals and market analytics providers.

We are platform-neutral. We are a Databricks Partner, we have delivered production platforms on Microsoft Fabric and Azure, and we resell neither. The architecture follows your environment, your team's skills and what the portfolio needs.

Platforms in production

Clients are not named here without their permission; references are available on request.

Current · US · wind, solar and storage

An Azure and Databricks platform for a multi-technology operator

We designed and built the platform and run it day to day: monitoring, incident recovery, access and governance, cost and storage housekeeping, and a managed improvement backlog. It uses Azure Data Lake Storage, Azure Databricks with Unity Catalog, Azure SQL and Power BI. It brings together operational, market, financial and weather data, and gives the client's own analysts a place to build and publish their tools.

Approach

The same people define it and build it

Assessments and advisory work are scoped to the question and end in written findings and a recommendation. A new data platform follows the sequence on the right, so you see working software from the first month.

  1. Platform foundation

    Identity, networking, storage zones, repositories, deployment pipelines, cost controls and monitoring, in your cloud tenant.

  2. First production source

    One priority source end to end: raw archive, transformation, reconciliation, alerts and failure handling. This sets the pattern.

  3. Integrated platform

    The remaining sources on the same pattern, running independently, feeding a reconciled reporting model.

  4. Reporting and go-live

    Dashboards accepted by their owners, documentation and runbooks, and hands-on time with your own engineer.

  • Built in your tenant from day one. You contract the cloud services directly, with no resale markup.
  • You own everything. Data, code, repositories, infrastructure definitions, documentation and credentials stay under your control throughout.
  • Pipelines are monitored and alert on failure.
  • Reported figures are validated against the source systems before they are published.
  • Infrastructure is code, versioned in your repositories, so the platform can be rebuilt or moved.
