Grid-connected — HOMER Grid + HOMER Pro

Design the campus microgrid that meets your carbon goals and your budget

HOMER software helps universities and institutional campuses design integrated energy systems—combining solar, CHP, battery storage, and intelligent grid interaction to hit net-zero targets while reducing energy costs.

Campuses are cities in miniature—with all the energy complexity that implies

A university campus has dozens of building types (labs, dormitories, lecture halls, athletic facilities), diverse load profiles, and often its own distribution system. Energy budgets of $10–50M+ annually are common. Meanwhile, institutional boards and student bodies are demanding aggressive carbon neutrality timelines. Designing a campus energy system that balances sustainability ambitions, budget reality, resilience needs, and operational complexity requires sophisticated modeling.

Universities & Campus Microgrids

Critical pain points

Where campus energy planning gets blocked

Universities must optimize across competing priorities, aging infrastructure, and pressure for visible decarbonization results.

Diverse, complex loads

Labs, data centres, dormitories, and athletic facilities each have radically different load profiles, schedules, and critical power needs. One-size-fits-all approaches fail.

Planning complexity

Aggressive carbon targets

Net-zero by 2035 or 2040 commitments are common. Boards and students demand visible progress, but the path from commitment to implementation requires detailed analysis.

Decarbonization pressure

Constrained capital budgets

Higher education budgets are under pressure. Energy investments must compete with academic priorities and demonstrate clear financial return or avoided cost.

Budget scrutiny

Thermal + electrical loads

Many campuses have district heating/cooling systems. Optimizing across both electrical and thermal energy domains is essential but analytically complex.

Multi-domain optimization

The analytical foundation for campus energy transformation

HOMER software provides the techno-economic modeling universities need to plan their energy transition. HOMER Grid optimises behind-the-meter solar + storage + CHP against your utility tariff. HOMER Pro designs any off-grid or islanding-capable microgrid components. Together, they model the full campus energy system—electrical and thermal—to find the path that meets your carbon goals at the lowest lifecycle cost.

Core modeling advantages

How HOMER turns campus complexity into action

From CHP dispatch to phased investments, HOMER gives facilities and finance teams one shared analytical baseline.

Campus-Wide Modeling

Model diverse building loads, central plant operations, and distributed generation in a unified analysis. Account for seasonal variation (academic calendar, summer research, break periods).

Unified decision model

CHP Optimization

For campuses with district heating or cooling, model combined heat and power systems that dramatically improve total energy efficiency and reduce both electricity costs and heating fuel consumption.

Thermal-electric efficiency

Phased Implementation

Use Multi-Year analysis to plan a staged energy transition: solar in year 1, battery storage in year 3, CHP upgrade in year 5. Show the cumulative cost and carbon impact of each phase.

Roadmap confidence

Additional Capabilities

  • +Combined Heat & Power module: Essential for campuses with steam or hot water distribution. Model CHP waste heat recovery for heating and absorption cooling.
  • +HOMER Pro: Design islanding-capable microgrids for critical research facilities, medical centres, or emergency shelters on campus.
  • +Multi-Year module: Model the entire campus energy roadmap: 10–20 year projections with load growth, equipment lifecycle, rate escalation, and carbon reduction milestones.
  • +Advanced Load: Separate critical research loads from deferrable loads like athletic lighting to optimise dispatch and resilience.

Use Case: Net-zero energy roadmap for a state university

The Situation

A 30,000-student state university spends $28 million annually on electricity and natural gas. The campus has a central CHP plant (aging and due for replacement), 45 buildings, and a board resolution requiring carbon neutrality by 2040. Current renewable energy: a 500 kW demonstration solar array. The facilities team needs a credible, phased roadmap showing how to get from 2% renewable energy today to net-zero within 15 years, with clear cost projections that the board can approve.

What Was Modeled

Using HOMER Grid and HOMER Pro with the CHP module, the university's energy consultant modeled the entire campus: building-by-building load profiles, existing CHP output, district heating demand, and grid electricity consumption. They evaluated a phased approach: Phase 1 (years 1–3): 5 MW distributed solar + 4 MWh battery. Phase 2 (years 4–6): new 3 MW high-efficiency CHP system. Phase 3 (years 7–10): additional 3 MW solar + 8 MWh storage + building electrification. Multi-Year analysis projected performance through 2040.

The Outcome

The roadmap achieves 75% carbon reduction by 2035 and net-zero by 2039. Total investment: $42M over 15 years. Net present value of energy savings: $58M—a positive ROI that funds the transition with utility cost avoidance. Phase 1 alone saves $3.2M annually and reduces carbon by 22%. The new CHP in Phase 2 adds $4.1M in annual savings through combined electrical and thermal efficiency. HOMER's analysis was presented to the Board of Regents and approved as the university's official Campus Energy Master Plan.
