Community Duration
Illustrative planning reference for a 60 MW IT campus; it is not a system offer, final design, or operating commitment. Final sizing must be recalculated from project load, SOC policy, degradation, efficiency, utility topology, market commitments, community-load evidence, and site-specific validation. Interconnection and campus-distribution voltages shown are conceptual only.
System Architecture
Layer 1
Utility / ERCOT Grid
• POI / Interconnection
• Project-funded upgrades
• Grid import / approved export
• ERCOT / QSE dispatch interface
Layer 2 — LGAI Reference Case
Data Center Energy Platform
• 60 MW IT / ~72 MW facility peak
• BESS: 100 MW / 500 MWh (recommended)
• Emergency critical campus load: 60 MW
• Community reserve: 20 MW / 80 MWh
• EMS / PMS / telemetry / protection
Layer 3 — Community Reserve
Community Grid Capacity
• Water / wastewater
• Medical / shelters
• Public safety / telecom
• Direct service via utility-approved electrical path
Operating Distinction
Grid support: reduce site withdrawal or export where authorized. Market participation: qualified load/BESS follows ERCOT/QSE dispatch. Resilience: requires utility-approved feeder/microgrid path.

Scenario Explorer
Each scenario represents a different scale, community relationship, and infrastructure configuration. Select one to see its planning parameters. All values are illustrative — final sizing requires site-specific engineering.
A single-campus deployment where BESS, solar, and utility feeds form a coordinated microgrid serving the institution and selected adjacent loads.
IT Load Range
20–60 MW
BESS Range
40–100 MW / 160–500 MWh
Community Reserve
5–20 MW reserve for campus-adjacent critical services
Solar Potential
5–15 MW on-site PV where land and interconnection allow
Key Planning Question
Does the campus have a single POI and enough contiguous land for co-located storage and PV?
Reference
UC San Diego Microgrid — LG-CS-008 →All scenarios are vendor-neutral planning concepts. They do not represent system offers, equipment endorsements, or delivery commitments. Final parameters depend on site, utility, regulatory, and engineering validation.
BESS Sizing Framework
These tiers are illustrative planning scenarios, not a system offer or delivery commitment. They help stakeholders compare potential relationships among facility load, duration, storage, selected priority loads, and utility constraints before an engineering team validates the configuration.
Baseline Grid Management
80 MW
320 MWh
Covers 60 MW critical facility load for ~4 hours. No community reserve. Grid-management only.
Minimum Meaningful
80 MW
450 MWh
Extends duration to ~5.6 hours at 60 MW. Limited community reserve possible with utility coordination.
Recommended Reference Case
100 MW
500 MWh
60 MW critical facility load + 20 MW / 80 MWh community reserve for 4 hours. LGAI planning reference.
Enhanced Resilience
120 MW
800 MWh
Extended duration and expanded community reserve. For sites with critical community infrastructure adjacent.
System Behavior
MODE 01
Indicative utility-plus-storage optimization scenario. The project team defines whether peak shaving or demand management is feasible after site-specific load, tariff, control, and interconnection review.
MODE 02
A potential operating scenario in which storage supports selected loads during defined demand periods. Actual dispatch, rate effects, and grid impact require utility, tariff, and engineering validation.
MODE 03
A potential continuity scenario for specifically selected loads during a grid disturbance. Final behavior depends on protection, switching, state of charge, controls, utility rules, and approved operating authority.
MODE 04
A conceptual staged-load and recovery scenario. Any campus or community support pathway requires a utility-approved electrical path, safety approach, metering, authority, and operating agreement.
Qualified Delivery Pathways
LGAI is vendor-neutral in planning, rigorous in qualification, and partner-ready in delivery. Equipment pathways may include qualified global battery OEMs, electrical integration partners, utilities, engineers, and site-specific control systems.
Battery System Pathway
Qualified Battery OEM and Enclosure Scope
A project team must identify the exact battery architecture, capacity, duration, enclosure approach, thermal-management design, battery-management system, safety documentation, warranty, commissioning responsibility, and long-term service pathway for the specific site.

Electrical and Control Integration Pathway
PCS, Protection, MV, EMS, and Operating Interfaces
Final delivery requires a clear electrical and operating interface among the utility, substation, power-conversion system, protection scheme, energy-management system, selected campus/data-center loads, and any approved resilience or market operating rules.
PCS
Power-flow requirement
Protection
Site-specific coordination
MV equipment

Telemetry
Named data-interface plan
Commissioning
Acceptance scope required
Each project moves from indicative concept to source-backed planning, then to engineering validation. LGAI does not publicly identify equipment suppliers, product claims, performance percentages, safety certifications, or delivery timelines unless the exact system and evidence have been qualified for that project.
Texas Regulatory Alignment
On August 3, 2026, Governor Abbott directed PUCT and ERCOT to audit all data centers on five specific criteria. Every single criterion maps directly to an LGAI framework layer.
Abbott Requires
Financial Self-Sufficiency
LGAI Layer
Layer 1 — AI Readiness Assessment
How LGAI Addresses It
LGAI evaluates the full financial structure of any proposed partnership — subsidies, tax abatements, and what the community actually receives.
Abbott Requires
Power Self-Sufficiency
LGAI Layer
Layer 2 — Infrastructure Feasibility
How LGAI Addresses It
LGAI evaluates indicative BESS and clean-energy pathways alongside utility capacity, load, controls, and site conditions; each path remains subject to source-backed planning and engineering validation.
Abbott Requires
Water Sourcing
LGAI Layer
Layer 2 — Infrastructure Feasibility
How LGAI Addresses It
LGAI's water strategy domain evaluates WUE, source water, reclaimed water, drought operation, and closed-loop cooling.
Abbott Requires
Community Protection
LGAI Layer
Layer 3 — Deal Structure & Guardrails
How LGAI Addresses It
LGAI helps stakeholders assess whether a proposed community-benefit and priority-load structure has a defined electrical path, operating authority, measurement method, and responsible parties.
Abbott Requires
Ownership Transparency
LGAI Layer
Layer 3 — Deal Structure & Guardrails
How LGAI Addresses It
LGAI's deal structure framework requires full ownership disclosure, beneficial ownership, and governance transparency before any partnership advances.
Ready to Evaluate Your Corridor?
LegacyGrid AI evaluates whether your site, corridor, or campus can support the Community Grid Asset model — and what it would take to structure a partnership that benefits the surrounding community, not just the data center operator.
Important Boundary
The Community Grid Asset model is a planning framework, not a guaranteed outcome. BESS cannot be claimed to directly power community meters until a utility-approved electrical path, protection/islanding scheme, metering, switching authority, and operating agreement exist. LegacyGrid AI helps evaluate and structure the path to that outcome — it does not guarantee it.
