# Core Monitoring KPIs

### Overview

The *Core Monitoring KPIs* is a Certified Product Point Template for [Wind Turbines](/product/docs/wind-turbine) defines required normalized performance KPIs that provide first-principles performance metrics for all vendors of [Wind Turbines](/product/docs/wind-turbine). The metrics here specifically leverage the raw data in the [*Core Real-Time Data template*](/product/docs/core-real-time-data-2) (e.g. the collection “raw” OPC points expected on all wind turbines) and the normalized calculations in the [*Core Real-Time Calculations template*](/product/docs/core-real-time-calculations-turbine).

These calculations specifically translate OEM-specific signals into consistent indicators of operational state, availability, communication status, and event conditions. By abstracting vendor-specific complexities, the Core Real-Time Calculations enable unified fleet monitoring, reduce configuration overhead, and support consistent reporting and alarm management across heterogeneous turbine technologies. This template is foundational for delivering reliable insights in mixed-portfolio environments.

### Template Definition

The *Core Monitoring KPIs* is based on a five-minute aggregation layer, formed from inter-related interval expressions (see below).

- **Scale Equations:** Algebraic or logical manipulations of input data done on the [Bazefield edge buffer](/product/docs/edge-buffer)
- **Online Expressions:** Algebraic or logical manipulations of input data done on the central Bazefield data engines (typically on a [storage node](/product/docs/storage-node)). Similar to scale equations in purpose, but done in the centralized architecture.
- **Interval Expressions:** Algebraic, logical, or advanced manipulations of input data done within a pre-define aggregation interval (e.g. 5 minutes, 10 minutes, 1 hour, etc). These are typically done centrally on a [storage node](/product/docs/storage-node).

Details on the Point Names, Descriptions, and Types are below.
