Microgrids and hybrid systems are where renewable economics get genuinely hard: solar, storage, generators, tariffs, outage costs, and incentive stacks interacting in one optimization. The software that models them decides whether a project pencils honestly or optimistically — and unusually for energy software, most of this category publishes real price lists. This guide compares the design and techno-economic platforms on identical criteria, from a university lab’s free optimizer to enterprise design-and-operate suites.
Behind-the-meter economics: HOMER Grid — demand-charge and tariff-driven projects.
Design-to-operate depth: XENDEE — power flow to financing in one platform, from $440/user/mo.
Storage proposals at sales speed: Energy Toolbase — ETB Developer from $299/user/mo.
Free academic-grade optimizer: DER-CAM — Berkeley Lab’s DER workhorse.
Emerging-market programs: Odyssey — the minigrid portfolio and procurement layer.
Scope: software for designing and economically optimizing microgrids, minigrids, and behind-the-meter hybrid systems — generation mix sizing, dispatch simulation, tariff and incentive economics, and proposal outputs. Utility-scale plant design lives in our solar design comparison; fleet trading in the battery optimization guide. Six entries, identical criteria; order follows analytical depth and workflow role, not rank.
Criteria: optimization approach, technology coverage, typical users, licensing model, workflow outputs, and the main tradeoff. This category is refreshingly transparent on price — public figures are cited as listed by vendors (checked September 19, 2026).

Pricing checked September 19, 2026. Most platforms in this category sell quote-based enterprise plans; where we cite figures they come from vendor pages or published third-party comparisons and are order-of-magnitude indications, not offers. Billing basis (per user, per MW, per site) varies by vendor — confirm current terms directly before budgeting.
The Platforms in Detail
HOMER Pro
The techno-economic reference
Best for: engineers and analysts sizing islanded, off-grid, or resilience-driven systems where the generation mix itself is the question.
| Optimization approach | Simulates thousands of configurations across sensitivity ranges; ranks by lifecycle cost |
| Technology coverage | PV, wind, storage, gensets, hydro, biomass, hydrogen, CHP via modules |
| Typical users | Consultants, NGOs and DFIs, campus and island planners, militaries |
| Licensing | Public price list — Base $1,575/yr, Professional $3,100/yr (any 4 modules), Expert $4,650/yr (all modules); monthly options; 25% volume discount at 4+ seats. Checked September 19, 2026 |
| Pedigree | Born at NREL, commercialized by HOMER Energy, now part of UL Solutions |
| Main tradeoff | Techno-economic sizing, not electrical engineering — no power flow, no protection studies |
- The de facto language of hybrid feasibility: DFIs, tenders, and reviewers worldwide expect HOMER-style least-cost tables, which makes its outputs unusually portable.
- Sensitivity-first design — sweeping fuel prices, load growth, and resource years in one run — matches how off-grid uncertainty actually behaves.
- Module pricing keeps entry honest: a solar-storage-genset study needs the Base tier, not the Expert one.
HOMER Grid
The tariff economist
Best for: teams whose projects live or die on demand charges, rate structures, and incentive stacks rather than islanding.
| Optimization approach | Behind-the-meter dispatch against real utility tariffs; demand-charge reduction and arbitrage |
| Technology coverage | Solar, storage, EV charging, gensets in grid-tied configurations |
| Typical users | C&I developers, ESCOs, storage sales engineering teams |
| Licensing | Public list pricing in the $4,200–10,100/yr range by edition (per UL’s published price list). Checked September 19, 2026 |
| Pedigree | The grid-tied sibling in UL’s HOMER family |
| Main tradeoff | US-tariff-centric strengths; engineering depth still lives elsewhere |
- Demand-charge modeling with real tariff libraries is the difference between a storage pro forma and a storage guess in C&I markets.
- Incentive handling — ITC variants, SGIP-style programs — keeps the economics current where projects actually clear.
- Pairs naturally with HOMER Pro: one family covers the islanded and grid-tied halves of a hybrid portfolio.
XENDEE
The engineering-grade platform
Best for: organizations that need one auditable chain from techno-economic sizing through power flow to operating strategy.
| Optimization approach | MILP-based optimization plus electrical analysis — power flow, one-lines — and multi-year planning |
| Technology coverage | 25+ DER technologies including hydrogen, EV fleets, CHP |
| Typical users | Engineering firms, utilities, data-center and defense resilience programs |
| Licensing | Public price list — DESIGN Gold $440/user/mo (annual), Platinum $540/user/mo annual or $650 monthly; Enterprise bundles quoted. Checked September 19, 2026 |
| Pedigree | Academic optimization lineage productized for professional design |
| Main tradeoff | Priced and built for professionals — overkill for quick screening |
- Closes the classic gap between the economic model and the electrical one — the sizing that pencils is checked against the physics that must build.
- Multi-year and multi-objective optimization suits the projects this decade actually funds: phased builds, resilience mandates, decarbonization targets in tension.
- Transparent per-seat pricing with published tiers is rare at this depth — budgeting an engineering team is arithmetic, not negotiation.
Energy Toolbase
The proposal engine
Best for: storage and solar sales teams who need bankable-looking C&I proposals at the pace deals actually move.
| Optimization approach | Tariff-accurate savings modeling and storage dispatch for proposals; monitor/control products operate what sells |
| Technology coverage | Solar plus storage behind the meter, with control (Acumen AI) and monitoring lines |
| Typical users | Developers, installers, and ESCOs selling C&I projects |
| Licensing | Public price list — ETB Developer from $299/user/mo (annual, 1 user) and $333/user/mo business tier; ETB Monitor from $7,500; ETB Controller from $34,000. Checked September 19, 2026 |
| Pedigree | A C&I storage-economics staple, now spanning propose-monitor-control |
| Main tradeoff | Sales-cycle depth, not microgrid engineering — islanding studies live elsewhere |
- Tariff fidelity where deals are won: utility-rate nuance in the proposal is this category’s real moat, and ETB built its brand on it.
- Propose-to-control continuity means the assumptions sold are the assumptions operated — and measured against.
- Entry pricing a small installer can carry, with hardware-anchored tiers appearing only when projects do.
DER-CAM
The free rigor check
Best for: analysts who want peer-reviewed optimization — and a zero-cost second opinion on any vendor’s sizing.
| Optimization approach | MILP optimization of DER investment and dispatch, from Lawrence Berkeley National Laboratory |
| Technology coverage | PV, storage, CHP, thermal loads and more in microgrid configurations |
| Typical users | Researchers, public agencies, rigorous developers |
| Licensing | Free |
| Pedigree | Two decades of DER-optimization research embodied in one tool |
| Main tradeoff | Research UX and support — capability without hand-holding |
- The independent check that keeps everyone honest: when DER-CAM and a commercial tool disagree materially, the discrepancy is always worth understanding before capital moves.
- MILP formulation handles thermal-electric coupling — CHP, heating loads — that simpler screeners approximate away.
- Free access makes it the classroom and public-sector standard, which quietly seeds its assumptions across the industry.
Odyssey
The program-scale layer
Best for: funders, programs, and developers running distributed renewable portfolios across emerging markets.
| Optimization approach | Portfolio workflow — project data, procurement, performance benchmarking — rather than single-site physics |
| Technology coverage | Minigrids and distributed solar portfolios; standardized data across many sites |
| Typical users | DFIs and results-based-financing programs, national agencies, minigrid developers |
| Licensing | Platform and program tooling; quote-based |
| Pedigree | The workflow backbone for major electrification programs across Africa and beyond |
| Main tradeoff | A portfolio and financing layer — pair it with HOMER-class tools for site design |
- Solves the problem single-site tools cannot see: making hundreds of small projects investable through standardized data, procurement, and verification.
- Results-based financing runs on exactly the performance evidence the platform structures — disbursement without spreadsheet archaeology.
- Aggregated procurement across portfolios attacks the cost stack where emerging-market projects actually bleed.
Why This Category Publishes Prices When Others Hide Them
Microgrid modeling grew out of research labs and engineering practice, not enterprise sales — NREL lineage in HOMER, Berkeley Lab in DER-CAM, academic optimization in XENDEE. Its buyers are consultants and installers who purchase like professionals buying instruments: per seat, list price, this quarter. The result is the most price-transparent corner of renewable software, and a useful benchmark for what enterprise vendors’ quote-based pricing is actually hiding.
Transparency has not meant commoditization. The tools have stratified by question instead: what mix to build (HOMER Pro, DER-CAM), what the tariff makes it worth (HOMER Grid, ETB), will it work electrically and operationally (XENDEE), and how do many such projects become a financeable portfolio (Odyssey). Sophisticated organizations own two or three deliberately rather than stretching one past its design intent.
Sequencing From Feasibility to Fleet
Screening starts free or cheap: DER-CAM or HOMER Pro Base establishes whether a configuration deserves engineering at all, with sensitivity sweeps standing in for the certainties nobody has. Grid-tied C&I economics then move into HOMER Grid or ETB, where tariff fidelity — not physics — separates winners.
Projects that survive graduate to XENDEE-class engineering, where the pencil meets power flow, protection, and multi-year operating strategy; sold systems hand their assumptions to monitoring and control so performance is measured against the promise. Program-scale work inverts the order — Odyssey-style portfolio structure first, site tools inside it — because in results-based financing the portfolio, not the site, is the unit of bankability.
Kurums Match: Which One Fits You?
Pick the statement that sounds most like your situation.
We size off-grid and resilience systems for clients and funders.
HOMER Pro is your lingua franca — reviewers expect its least-cost framing — with DER-CAM as the free second opinion on contested designs. Add modules only when project types demand them; the Base tier carries most solar-storage-genset work.
We sell C&I solar-plus-storage against demand charges.
Energy Toolbase for proposal velocity or HOMER Grid for analytical depth — many teams run ETB commercially with HOMER Grid as the pre-contract check on large deals. Tariff-library quality in your specific utilities should decide the primary seat.
We engineer campus, defense, or data-center microgrids end to end.
XENDEE is built for exactly this arc — economics, power flow, and operating strategy in one auditable platform. Keep DER-CAM in the loop as the independent optimizer your review board will thank you for.
We run electrification programs across emerging markets.
Odyssey for portfolio structure, procurement, and performance verification; HOMER Pro inside it for site design your funders already know how to read. The free atlases and Solargis-grade data feed both — see our siting guide.
Frequently Asked Questions
HOMER Pro or HOMER Grid — which one do we need?
Islanded or resilience-first questions — what mix keeps the lights on at least cost — point to Pro. Grid-tied questions ruled by tariffs and demand charges point to Grid. Portfolios spanning both commonly license both; the family is priced to allow it.
Is free DER-CAM genuinely a substitute for commercial tools?
For optimization rigor, often yes; for workflow, no. You trade interface polish, support, and proposal outputs for peer-reviewed depth at zero cost. It shines as the independent check and in public-sector settings where procurement favors free tools.
Where does microgrid software stop and utility-scale design begin?
Roughly at the meter and the megawatt scale: these tools optimize consumption-side and islanded systems. Utility-scale plant engineering — PVsyst, PVcase, RatedPower — is covered in our solar design comparison; merchant storage trading in the battery optimization guide.
How current are the tariff and incentive libraries really?
Current enough to sell with, never current enough to close on. Vendors update continuously, but rate cases and incentive rules move faster — validate the specific tariff and incentive stack against source documents before contracts are signed.
