Pros
Cons
TL;DR: Energy Toolbase is the financial modeling platform of choice for C&I solar-plus-storage developers who need lender-accepted accuracy, deep utility rate coverage, and AI-powered storage dispatch. At $199/user/month ($2,388/year), it delivers what institutional financiers require — but it does not design, it does not generate SLDs, and it cannot replace a design platform. Based on verified customer case studies, users processing complex C&I storage deals see 87–94% time savings on proposals. For teams needing a complete workflow — design, simulation, financials, and proposals — SurgePV — the leading solar design software — handles everything in one platform at $1,499/user/year.

What Is Energy Toolbase?
Energy Toolbase is a cloud-based financial modeling and energy storage optimization platform built for commercial solar and storage developers. It was founded in 2014 by John Gurski in San Francisco, CA, and acquired by Pason Systems Inc. (TSX: PSI) in November 2023.
The platform does one thing better than any other software on the market: it models the financial case for solar-plus-storage projects with a level of accuracy and credibility that institutional lenders actually accept.
Company Background
| Detail | Info |
|---|---|
| Founded | 2014 by John Gurski |
| HQ | San Francisco, CA |
| Parent Company | Pason Systems Inc. (TSX: PSI) — acquired November 2023 |
| Employees | 91 across North America and Europe |
| Customers | 1,500+ distributed energy organizations worldwide |
| Coverage | All 50 US states + Canada + Mexico + 42 international territories |
| Recognition | Inc. 5000 America’s Fastest-Growing Private Companies |
The Pason Systems acquisition matters. Pason is a publicly traded energy technology company, which means Energy Toolbase now has institutional backing, structured R&D budgets, and long-term product stability. For enterprise EPCs evaluating software risk, that carries weight.
What Energy Toolbase Actually Does
Energy Toolbase is not a solar design tool. It does not draw panels, simulate shading, or generate single-line diagrams. It begins where design ends.
The platform takes production data from your design tool — via 8760 export from HelioScope, Aurora, Scanifly, or PVsyst — and runs the financial analysis: utility bill modeling, demand charge reduction, TOU arbitrage, battery sizing, NPV, IRR, payback, and 25-year cash flow projections.
This specialization is both its strength and its primary limitation.
Energy Toolbase Position in the Stack
Energy Toolbase sits between design (HelioScope, Aurora, SurgePV) and project execution. It replaces spreadsheet-based financial modeling — not the design platform itself. Most users run at least two platforms in their workflow.
Product Suite Overview
Energy Toolbase ships four products:
ETB Developer — The main financial modeling and sales platform. Prices at $199/user/month. This is what most teams buy.
Acumen EMS — AI-powered energy management system for deployed projects. Controls battery dispatch with 15-minute forecast regeneration. Custom pricing.
ETB Monitor — Real-time asset monitoring with actual vs. projected savings tracking. Custom pricing (approximately $4,500 per site for a 5-year subscription, per third-party sources).
ETB Consulting — A pay-as-you-go detailed analysis service via dedicated app, launched August 2024. Pricing not disclosed.
Energy Toolbase Pricing & License Cost
Energy Toolbase pricing is straightforward for the main product and opaque for everything else.
Energy Toolbase License Price 2026
| Product | Price | Billing | What You Get |
|---|---|---|---|
| ETB Developer | $199/user/month | Monthly | Financial modeling, 70,000+ utility rates, storage analysis, proposal generation |
| ETB Developer (annual) | ~$179/user/month | Annual (10% discount) | Same as above at reduced rate |
| Acumen EMS | Custom | Contact sales | AI battery dispatch, multi-value optimization |
| ETB Monitor | Custom | Per project | Real-time monitoring, actual vs. projected |
| ETB Consulting | Not disclosed | Pay-as-you-go | Detailed analysis via app |
June 2024 was the first price increase in Energy Toolbase’s 10-year history. The $199/month rate reflects that history — the platform held pricing flat for a decade before this increase.
Total Cost of Ownership: The Real Number
ETB Developer alone is $2,388/year. But Energy Toolbase does not design. To run a complete C&I workflow, you need to add design and electrical tools:
| Workflow Component | Tool | Annual Cost |
|---|---|---|
| Financial modeling | Energy Toolbase (ETB Developer) | $2,388/user |
| Solar design | HelioScope ($149/month) or Aurora ($200–400/month) | $1,788–$4,800/user |
| SLD / electrical | AutoCAD | $2,030/user |
| CRM | HubSpot Starter or Salesforce | $300–$3,600/user |
| Full stack total | $6,506–$12,818/user/year |
Compare to SurgePV’s generation and financial tool at $1,499/user/year (3-user plan), which includes design, simulation, financial analysis, and proposals in one platform.
Hidden Costs
Energy Toolbase does not disclose pricing for Acumen EMS, ETB Monitor, or training. Implementation costs, onboarding support tiers, and custom integrations are all “contact sales.” Request a full quote before budgeting.
Is Energy Toolbase Free? Free Trial
Energy Toolbase does not offer a public free trial. Demo access is available on request through their sales team at (866) 415-1445 ext. 1.
Given the 4–6 week learning curve, a standard 14-day trial would not provide enough time to evaluate the platform properly. If you are seriously evaluating Energy Toolbase, ask for a structured pilot period with onboarding support rather than a time-limited demo.
There is no freemium tier or entry-level free plan.
Core Features & Capabilities
Utility Rate Database: The Main Differentiator
Energy Toolbase maintains 70,000+ utility rate schedules across 1,200+ utility territories — covering all 50 US states, Canada, Mexico, and 42 international territories. This is the feature users mention first.
The database is maintained by an in-house utility rates team that contacts utilities directly to verify rate changes. Most competitors rely on automated web scraping or public utility filings. Energy Toolbase’s manual verification means fewer modeling errors from outdated rates.
For C&I projects where demand charge reduction is the primary value driver, rate accuracy directly determines whether the project pencils. Getting it wrong by even one rate structure can flip a project from positive to negative IRR.
Why Rate Accuracy Matters
Demand charges can represent 30–50% of a commercial customer’s electric bill. If your financial model uses the wrong demand charge rate, your savings projections are wrong — and so is the customer’s decision. Energy Toolbase’s rate verification is why lenders trust its output.
Financial Modeling
ETB Developer generates full financial models covering:
- NPV, IRR, payback period, LCOE, and 25-year cash flow projections
- NEM 1.0, 2.0, and 3.0 modeling
- Custom rate schedules and incentive modeling (ITC, IRA, USDA REAP, SGIP)
- PPA and lease financing structure modeling
- Multi-site portfolio analysis
- Lender-ready output that matches PVSyst within ±2%
The ±2% PVSyst accuracy claim is significant. Institutional lenders require financial models with documented accuracy thresholds — Energy Toolbase’s output is one of the few platforms lenders specifically accept without requiring independent validation.
Energy Toolbase Storage Modeling
Storage optimization is the second major differentiator. The platform models battery dispatch across multiple value streams simultaneously:
- Demand charge reduction — shaving peak demand to reduce the demand component of the bill
- TOU arbitrage — charging during cheap off-peak hours, discharging during expensive peak periods
- Grid services — demand response participation, frequency regulation revenue
- PV self-consumption — maximizing on-site solar use to minimize export at low rates
- DC clipping recapture — capturing energy that would otherwise be clipped by inverter limits
The Acumen EMS product takes this further. It uses machine learning with 24-hour load forecasting, regenerated every 15 minutes, to dispatch battery storage in real time across deployed projects. It is hardware-agnostic, working with Dynapower, Socomec, Sungrow, SolarEdge, Tesla, and other manufacturers.
This is not modeling — it is live control of deployed storage assets. For VPP operators and fleet managers, this capability has no direct equivalent in design-first platforms like Aurora or SurgePV.
Proposal Generation
ETB Developer includes proposal generation with branded web URLs. The proposal auto-populates from the financial model, eliminating manual data transfer.
Supported financing structures:
- Cash purchase
- Loan (with custom amortization schedules)
- PPA (Power Purchase Agreement)
- Lease
- PACE and other on-bill financing structures
SunGreen Systems reported cutting proposal time from 16 hours to 1–2 hours per project (87–94% reduction) after switching to Energy Toolbase for C&I storage proposals.
Integrations
Energy Toolbase integrates with the design tools it depends on:
| Category | Integrations |
|---|---|
| Design software | HelioScope, Scanifly, Solesca, Aurora (via 8760 export), PVWatts, PVsyst |
| Utility data | UtilityAPI, Green Button |
| Financing | Green Bridge Energy, Luminia, Sunstone Credit, K2 Clean Energy Capital |
| Hardware | Dynapower, Socomec, Sungrow, SolarEdge, Tesla, and others |
CRM integration (Salesforce) is on the public roadmap but has no release date.
User Reviews & Feedback
Energy Toolbase does not have a significant presence on G2, Capterra, or TrustRadius — unusual for a platform serving 1,500+ organizations. This makes independent sentiment analysis harder than for Aurora Solar or Arka360, where hundreds of verified reviews exist.
What is available comes from verified customer case studies on the Energy Toolbase website and user comments in solar industry forums.
Verified Customer Outcomes
| Customer | Result |
|---|---|
| SunGreen Systems | Proposal time cut from 16 hours to 1–2 hours (87–94% reduction) |
| IGS Energy | Won 4+ MW healthcare project (13 systems, 5 sites) using ETB financial model |
| Renova Solar | Processes thousands of projects annually through ETB Developer |
| GenPro Energy Solutions | ETB adopted as the standard platform across the entire organization |
What Users Consistently Praise
Based on customer case studies and forum feedback:
| Feature | Sentiment |
|---|---|
| Utility rate accuracy | ”The most detailed rate database I’ve found” — recurring theme |
| Institutional credibility | Lenders ask for ETB output by name on complex deals |
| Storage modeling depth | Only platform handling multi-stream co-optimization out of the box |
| Customer support | Described as “gold standard for the industry” in multiple accounts |
What Users Consistently Criticize
| Issue | Severity |
|---|---|
| No design tools — workflow requires two platforms | High |
| 4–6 week learning curve | High |
| Complex interface for new users | Medium |
| No mobile access | Medium |
| No CRM integration (roadmap only) | Medium |
| Limited international utility coverage | Low for US teams |
“Significant onboarding delays” — a phrase appearing in multiple user accounts — points to a real friction point. Energy Toolbase is not plug-and-play. It rewards teams willing to invest in learning it properly, and struggles for teams that need immediate productivity.
Pros & Cons
Pros
1. Utility Rate Database — The Industry Standard
70,000+ manually verified rate schedules across 1,200+ territories. Competitors rely on scraping. Energy Toolbase pays a team to call utilities. For demand charge modeling, this accuracy difference can determine whether a project gets financed.
2. Lender-Accepted Financial Models
Output matches PVSyst within ±2%. Institutional lenders — banks, tax equity investors, and infrastructure funds — accept Energy Toolbase projections without requiring independent validation. For developers chasing institutional capital, this saves weeks of due diligence friction.
3. Energy Toolbase Storage Optimization
Multi-value stream co-optimization covers demand charge reduction, TOU arbitrage, grid services revenue, and DC clipping recapture simultaneously. The Acumen EMS live dispatch product extends this to deployed projects — no other design-first platform does this.
4. End-to-End Lifecycle Coverage
Model (ETB Developer) to Control (Acumen EMS) to Monitor (ETB Monitor). Most platforms stop at proposal generation. Energy Toolbase follows the project through operation and provides actual vs. projected savings verification.
5. Institutional Backing
Pason Systems (TSX: PSI) provides financial stability that pure-VC software companies lack. For enterprise EPCs signing multi-year software contracts, platform longevity matters.
6. Integration Ecosystem
Native data pipelines from HelioScope, Aurora, Scanifly, and PVsyst. Financing integrations with Luminia, Sunstone Credit, and K2 Clean Energy Capital for instant PPA quote generation.
Cons
1. No Design Tools — You Must Buy a Second Platform
Energy Toolbase does not design. Period. You need HelioScope ($1,788/year), Aurora ($2,400–$4,800/year), or equivalent. That second platform cost often exceeds ETB Developer itself. For teams that want one tool to handle design and financials, Energy Toolbase is not it.
2. No Electrical Engineering — AutoCAD Required
No SLD generation, no wire sizing, no conduit fill calculations. Complex C&I projects still need AutoCAD ($2,030/year) for permit-ready electrical documentation. SurgePV generates automated SLDs in 5–10 minutes with no external CAD tool.
3. No CRM or Project Management
No lead tracking, pipeline management, or e-signature capabilities. CRM integration (Salesforce) is on the roadmap without a release date. Data sits in silos across Energy Toolbase, your design tool, and your CRM.
4. 4–6 Week Learning Curve
Not a weekend setup. The platform requires dedicated onboarding. For teams with high staff turnover or small training budgets, this is a real operational risk.
5. No Mobile Access
Web-only architecture. No iOS or Android app for field use. The ETB Consulting app (launched August 2024) is a specialized standalone product, not a mobile version of ETB Developer.
6. Limited Public Reviews
No G2 or Capterra presence makes independent due diligence harder. Buyers are relying on vendor-provided case studies rather than third-party verified reviews.
Energy Toolbase vs SurgePV
These two platforms serve different functions. The comparison only makes sense in context: Energy Toolbase for pure financial modeling depth, SurgePV for complete C&I workflow integration.

| Storage financial model | 2–4 hours (ETB’s strength) | 30–45 min |
| Proposal | 30 min (ETB web proposal) | 15–20 min |
| Total | 7–11 hours | 1.5–2 hours |
Annual Cost Comparison
| Option | Software Stack | Annual Cost |
|---|---|---|
| Energy Toolbase complete stack | ETB + HelioScope + AutoCAD + CRM | $6,506–$12,818/user |
| SurgePV all-in-one (3-user plan) | Generation & financial tool included | $1,499/user |
When to Use Both
Some enterprise EPCs use SurgePV for design and daily workflow, then export to Energy Toolbase for institutional lender submissions requiring its specific accuracy credentials. This is a valid dual-platform strategy for high-value deals where lender credibility matters more than workflow efficiency.

Energy Toolbase Alternatives
If Energy Toolbase doesn’t fit your workflow or budget, these are the realistic alternatives to consider.
SurgePV — The all-in-one alternative for teams that want design, simulation, and financial modeling in one platform. SurgePV’s generation and financial tool handles NPV, IRR, payback, and cash flow projections alongside full 3D design and automated electrical documentation. Best for C&I EPCs that cannot afford the time and cost of a multi-tool stack.
Aurora Solar — A design-first platform with basic financial modeling built in. Aurora covers residential and commercial design well, with financial outputs adequate for most proposals. It does not match Energy Toolbase’s storage modeling depth or utility rate coverage, but eliminates the two-platform dependency. Best for teams doing design-led sales rather than storage-led deals.
HelioScope — HelioScope is a design and simulation tool that integrates directly with Energy Toolbase. Many teams run HelioScope + Energy Toolbase as their standard C&I stack. HelioScope handles design; Energy Toolbase handles financials. This is a functional combination at higher combined cost than all-in-one platforms.
Homer Energy — NREL’s microgrid and off-grid financial modeling tool. Homer covers scenarios Energy Toolbase does not: off-grid, diesel backup, islanded microgrids, and complex hybrid systems. If your project is a microgrid or remote energy system rather than grid-connected C&I, Homer is the better financial modeling tool.
PVWatts + Manual Modeling — PVWatts (free, NREL) provides basic production estimates, combined with Excel-based financial models. This works for simple residential projects but cannot handle demand charge optimization, complex storage dispatch, or institutional financing requirements. Energy Toolbase replaces this for teams doing serious C&I work.
OpenSolar — A free and low-cost design platform with basic financial outputs. OpenSolar has expanded its financial modeling capabilities but remains oriented toward residential and small commercial. Not a direct replacement for Energy Toolbase’s storage modeling or institutional credibility.
Who Should Use Energy Toolbase?
Choose Energy Toolbase When:
You are a C&I storage developer working with institutional financing. If your deals require lender-accepted financial models — project finance, tax equity, institutional debt — Energy Toolbase’s ±2% PVSyst accuracy and lender recognition make it hard to replace. No other commercial tool has the same institutional track record.
You need multi-value stream storage optimization. If demand charge reduction, TOU arbitrage, and grid services revenue are all part of the financial case, Energy Toolbase models the interactions between them in ways spreadsheets and basic tools cannot.
You already have a design platform and want to replace Excel for financials. If HelioScope or Aurora is already your design tool and you are modeling C&I storage financials in spreadsheets, ETB Developer will cut your modeling time by 85%+ while improving accuracy.
You manage deployed storage assets at scale. Acumen EMS and ETB Monitor serve a fleet management function no design tool provides. VPP operators and ESCOs managing 10+ deployed battery sites have few alternatives.
Choose SurgePV When:
You need design, financials, and proposals in one workflow. For EPCs running 20–100+ commercial projects per year, the two-platform dependency of Energy Toolbase adds friction that compounds at scale. SurgePV handles design through proposal in one environment.
You need automated electrical documentation. AutoCAD-free SLD generation matters when you are producing permit packages at volume. SurgePV generates complete SLDs in 5–10 minutes; Energy Toolbase generates none.
Your team cannot absorb a 4–6 week onboarding period. For teams that need to be productive within days, SurgePV’s 2–3 week ramp-up is more manageable.
You work in India or international markets. Energy Toolbase’s utility coverage outside North America is limited. SurgePV covers US and India with equal depth.
Frequently Asked Questions
What is Energy Toolbase?
Energy Toolbase is a solar-plus-storage financial modeling platform serving 1,500+ organizations. Founded in 2014 and acquired by Pason Systems (TSX: PSI) in 2023, it specializes in utility rate analysis, storage optimization, and bankable financial projections for C&I solar projects. It does not include design tools.
How much does Energy Toolbase cost?

Energy Toolbase specializes in financial modeling and storage optimization; Aurora Solar focuses on design and residential sales. Many C&I teams use both together. Aurora handles design; Energy Toolbase handles the institutional financial model.
Does Energy Toolbase have a free trial?
No public free trial is available. Demo access can be requested through their sales team. Given the 4–6 week learning curve, a meaningful evaluation requires a structured pilot with onboarding support.
Final Verdict
Energy Toolbase earns its reputation. The utility rate database is the most comprehensive in the solar industry. The storage modeling covers multi-value stream co-optimization that spreadsheets cannot replicate. And the lender-accepted financial accuracy (±2% vs PVSyst) removes friction on institutional financing deals.
Those strengths are real and specific. So are the limitations.
Strengths
- Industry-leading utility rate database — 70,000+ manually verified schedules
- Lender-accepted financial accuracy (±2% vs PVSyst)
- Multi-value stream storage optimization: demand charges, TOU, grid services, DC clipping
- Acumen EMS live storage dispatch — no design platform does this
- End-to-end lifecycle: model, control, monitor
- Institutional stability from Pason Systems ownership
Limitations
- No design tools — requires HelioScope or Aurora, adding $1,788–$4,800/year
- No SLD or electrical engineering — AutoCAD still required ($2,030/year)
- No CRM — data remains siloed
- 4–6 week learning curve
- No mobile access
- Limited public reviews for independent validation
The Decision Framework
Choose Energy Toolbase when: Your projects require institutional financing with lender-accepted financial models, your deal complexity involves multi-value stream storage optimization, and your team already has a design platform you are not replacing.
Choose SurgePV when: You want design, simulation, financials, and proposals in one workflow, need automated electrical documentation, work in India or international markets, or cannot justify a six-figure annual multi-tool stack.
Value Analysis
For a three-person C&I EPC team running 40 projects per year:
| Scenario | Annual Software Cost | Proposal Time/Project | Total Annual Hours |
|---|---|---|---|
| Energy Toolbase full stack | $19,500–$38,400 (3 users) | 7–11 hours | 280–440 hours |
| SurgePV all-in-one (3 users) | $4,497 | 1.5–2 hours | 60–80 hours |
The specialization Energy Toolbase provides has real value for the right buyer. For teams where institutional lender credibility is the constraint, that value justifies the cost. For the rest, the multi-platform friction and total cost are hard to justify against purpose-built alternatives.
