This is the fifth article in the Capco and Hartigen’s PowerOptix series ‘Commercializing power for the AI economy’, which explores how organizations are redefining generation, commercialization, and digital operations in the era of AI.

AI data centers are now as critical to the energy economy as power plants themselves. They operate at the intersection of technology, infrastructure, and commerce, where every megawatt consumed, stored or exported must be captured, validated, and monetized.

Creating a market-ready data center means establishing a commercial and digital foundation that connects physical power operations to financial, contractual, and environmental outcomes. That foundation is built through data accuracy, automated settlement, and transparent ESG reporting.

What it means to be market ready

For decades, utilities and market operators have built systems around regulated frameworks. Data centers and private generators operating behind the meter must now replicate those same capabilities independently.

A market-ready power environment must deliver:

• Accurate measurement of generation, consumption, and export data
• Automated application of PPA or tariff-based pricing logic
• Consistent settlement and invoicing for each customer or tenant
• Readiness for future participation in ISO or RTO markets
• Transparent ESG and emissions tracking.

This level of sophistication ensures that the data center can function as a self-contained energy enterprise, capable of managing its own commercialization lifecycle while remaining flexible for future grid integration.

The PowerOptix meter to cash backbone

PowerOptix serves as the digital foundation for market readiness. It integrates operational energy data with commercial, financial and environmental processes to create a unified, automated flow from meter to settlement.

PowerOptix capabilities:

• Meter data management (MDM) – Ingests, validates, and aggregates 15-minute or sub-hourly data across multiple sources
• Automated settlement and invoicing – Applies contractual formulas and schedules to generate accurate, auditable invoices
• Multi-tenant and shared infrastructure support – Manages individualized billing and allocation logic for complex campuses
• Market ready design – Maintains ISO compatible data structures for seamless export or participation
• ESG and emissions tracking – Provides traceable, auditable carbon data integrated directly into settlement processes.

PowerOptix functions as a standardized commercial and data interface between operational energy systems and downstream settlement, market, and ESG processes, similar to how USB-C provides a common interface while allowing underlying technologies to evolve.

This approach decouples generation and control systems from commercial settlement and compliance workflows, reducing vendor lock-in and long-term integration risk.

This framework allows private generation owners and data center operators to manage energy with the same precision as a regulated utility, without the same level of infrastructure complexity.

Integrating operations, commerce and compliance

The challenge for modern data centers is not only how to generate or purchase power, but how to manage it as a commercial asset.

Operational data must connect directly to contractual and compliance outcomes.  Capco and Hartigen’s joint approach ensures that:

• Operations – Meter data and fuel systems are integrated and validated
• Commerce – Contracts, PPAs, and pricing logic are automated through PowerOptix
• Compliance – ESG and emissions data are embedded within financial and audit processes.

This integration delivers a seamless, end-to-end digital backbone that ensures every transaction, from megawatts to invoices, is fully traceable and market-ready.

Transparency and ESG accountability

ESG reporting is no longer optional.  Investors, regulators and customers expect clear evidence of how each unit of energy is produced, consumed, and offset.

With PowerOptix, data centers can:

• Track carbon intensity across multiple generation types
• Align with GHG Protocol Scope 1, 2, and 3 reporting
• Link ESG performance directly to settlement data
• Provide audit-grade transparency for customers and partners

This level of accountability transforms sustainability from a reporting exercise into an operational advantage.

From private PPA to market participation

Even when operating privately, most behind-the-meter facilities are built with future market connectivity in mind.   By adopting market-ready data standards today, operators can later participate in ISO or RTO markets without needing to reconfigure their systems.

PowerOptix data structures and automation frameworks align with market protocols, ensuring that data centers can transition seamlessly from private bilateral agreements to regulated market participation when it becomes commercially advantageous, subject to defined operational and commercial guardrails that prioritize reliability and contractual obligations.

The Capco and Hartigen advantage

Capco and Hartigen PowerOptix provide the expertise and technology needed to bridge operations, commerce and compliance.

• Capco delivers the process design, integration strategy, and governance required for scalability and audit readiness
• Hartigen’s PowerOptix provides the digital platform that connects every data point from meter to invoice.

Together, they enable data centers operators and private generators to operate with utility-grade discipline while maintaining the agility of private enterprise.

Key takeaway

Building a market-ready data center means creating the digital and commercial systems that transform power from an operational input into a financial asset.

Capco and Hartigen PowerOptix are enabling this transformation by uniting metering, validation, settlement, invoicing, and ESG tracking into a single, transparent system. This is how the next generation of AI-scale infrastructure will manage power, not as a cost center but as a source of value and accountability.
