MPM Standardization Roadmap

Document Control Number: MPM-RMP-2026-003

Effective Date: October 2026

Associated Baseline Documents: MPM-CHR-2026-001 (Charter), MPM-GOV-2026-002 (Governance Structure)

Executive Summary

The MPM Standardization Roadmap defines the multi-year engineering trajectory, release schedules, and technical milestones for the Mechanical Power Module Consortium. The core objective is to transition distributed mechanical torque aggregation from custom industrial engineering to a globally standardized, vendor-neutral hardware primitive.

By establishing clear technical baselines across four distinct phases (2026–2030), this roadmap guides participating manufacturers, project developers, and certifying bodies toward interoperability for MPM units ($77\text{ kW}$ to $1\text{ MW}$ class), Multi-MPM Aggregator Adapters ($10\text{ MW}$ / $7.2\text{ GWh/month}$ blocks), and dedicated single-use off-grid systems.

Phase 3: Single-Use Industrial Direct Coupling & Scale-Up (Q2 2028 – Q4 2028)

Primary Lead: TWG-3 (Single-Use & Off-Grid Integration)

Extends standard torque output interfaces directly into high-value, off-grid industrial machinery, bypassing grid transmission queues and power conversion losses.

Core Deliverables:

- MPM-SPEC-304 ($1\text{ MW}$ Class Single-Unit MPM Specification): Upscaled individual module physical footprint, shaft torque envelope, and spline ratings for megawatt-class single prime movers.

Phase 4: Utility Integration, 3-High Stacking & Global Interoperability (Q1 2029 – Q4 2030)

Primary Lead: TWG-4 (Grid, Safety & Regulatory) & CCB

Enables hyperscale deployment, vertical array stacking, utility grid interconnection, and global certification compliance.

Core Deliverables:
- MPM-SPEC-401 (Multi-Tier Physical Stacking Mechanics): Structural interlocking, dynamic resonance suppression, and load-bearing framing for 3-high containerized adapter arrays ($30\text{ MPMs} \rightarrow 30\text{ MW}$ total, generating up to $21.6\text{ GWh/month}$).
- MPM-SPEC-402 (Synchronous Generator Matching & Grid Interconnection): Standardized automatic synchronizer interfaces, grid protection relay logic, multi-input emergency shutdown (ESD) loops, and anti-islanding safety protocols.
- MPM-SPEC-403 (Carbon Accounting & Operational Telemetry Protocols): Encryption standards and data format schemas for automated, tamper-proof reporting of mechanical work output to international carbon credit registries.
- MPM-CERT-001 (Consortium Interoperability Certification Manual): Test bench procedures, field audit criteria, and benchmark suites executed by accredited test facilities for granting the Consortium Interoperability Seal.

3. Engineering Benchmarks & Key Metrics

To ensure seamless field interoperability across diverse vendor hardware, all candidate specifications must validate performance against fixed mathematical thresholds:

3.1 Shaft Torque & Power Density Benchmarks

$77\text{ kW}$ Baseline Module:
$$\text{Torque } (T) = \frac{P}{\omega} \approx \frac{77\text{ kW}}{1,800\text{ RPM}} \approx 408.5\text{ N}\cdot\text{m}$$
$1\text{ MW}$ Upscaled Module:
$$\text{Torque } (T) = \frac{1,000\text{ kW}}{1,800\text{ RPM}} \approx 5,305\text{ N}\cdot\text{m}$$

3.2 Monthly Energy Output Capacity

$10\text{ MW}$ Adapter Array Baseline:
$$P_{\text{monthly}} = 10\text{ MW} \times 24\text{ hours/day} \times 30\text{ days} = 7,200\text{ MWh} = 7.2\text{ GWh/month}$$
$30\text{ MW}$ (3-High Stacked Array):
$$P_{\text{monthly}} = 30\text{ MW} \times 24\text{ hours/day} \times 30\text{ days} = 21,600\text{ MWh} = 21.6\text{ GWh/month}$$

3.3 Dynamic Balance & Vibration Suppression

Maximum permissible lateral movement at full rotational speed: $< 0.05\text{ mm/s}$ velocity RMS.
Torsional vibration transmission efficiency across multi-engine gearbox inputs: $\le 2.0\%$ peak torque oscillation across $5\text{ Hz}$ to $500\text{ Hz}$ spectrum.

4. Governance Integration & Revision Cadence

Working Group Execution: Draft specifications originate in the designated TWG and move through the four-stage lifecycle detailed in the MPM Governance Structure (MPM-GOV-2026-002).
Annual Roadmap Review: In Q4 of each operational year, the Technical Steering Committee (TSC) shall publish an updated revision of this roadmap, incorporating market feedback, power density advancements, and emerging industrial single-use applications.
Open Standards Alignment: Core spline profiles and fluid interfaces developed under this roadmap remain subject to the Consortium’s Mandatory Royalty-Free / FRAND Core Licensing Framework.
