Enterprise platform · 25+ buildings
Fleet-wide energy intelligence for property managers running 25+ buildings.
Portfolio-level optimization, aggregated VPP revenue, and BPS reporting that submits itself. Designed for Yardi, AppFolio, and Buildium shops who need compliance-grade numbers, not marketing math.
Portfolios with solar and battery consistently hit 20–30% energy-cost reduction — full-stack configurations (solar + battery + TOU + EV) reach 25–40%. Thermostat-only deployments average 8–15%. [How we calculate →]
What HarmonyGrid does
The operating system for a managed energy portfolio.
Four capability pillars. One data model. Built for VP-of-Ops reporting cadences — quarterly board decks, monthly ownership reviews, daily stand-ups.
Portfolio optimization
Coordinate HVAC, batteries, and solar across every building. Portfolio-weighted dispatch, not per-site guesswork.
- Aggregated VPP revenue across all managed sites
- TOU and demand-response scheduling per utility territory
- Weather-normalized baseline per building
Compliance reporting
BPS submission packets generate from the same data that runs your optimization. Auditable, versioned, exportable.
- Chicago Energy Benchmarking, WA Clean Buildings, OR BPS, NYC LL97
- Auto-fills from utility history via Green Button / Bayou
- Evidence log retained for 7 years
PMS integrations
Your accounting and maintenance system already knows the buildings. We sync with it rather than asking your team to rekey everything.
- Yardi, AppFolio, Buildium connectors
- Cost center mapping per owner entity
- Webhook and REST API for everything else
Security & access
Role-based staff access, audit logs, and encrypted utility credentials. Vendor security review on request.
- RBAC: owner, PM, technician, auditor roles
- SOC 2 posture in progress — see security section
- SSO via SAML / OIDC (enterprise tier)
Portfolio ROI
Three regions. Non-overlapping math. Every line ties to a utility program or benchmark.
These tables model a 10-unit building representative of each territory. Energy cost reduction already folds in TOU optimization where applicable — we don't double-count. VPP/DR revenue is only shown where a real program pays (ConnectedSolutions, CenterPoint Indiana, Renew Home CA). See full methodology →
New England
10-unit portfolio — annual impact
| Benefit | No Batteries | 2 Batteries | 5 Batteries |
|---|---|---|---|
| Energy cost reduction (8–15%) | $1,973–$3,699 | $1,973–$3,699 | $1,973–$3,699 |
| Solar self-consumption (4 of 10 units) | $0–$1,200 | $0–$1,200 | $0–$1,200 |
| VPP/DR (Powerwall 3, Eversource ConnectedSolutions) | $0 | $8,776/yr | $21,940/yr |
| Total annual | $1,973–$4,899 | $10,749–$13,675 | $23,913–$26,839 |
Baseline: 10 units × 700 kWh/mo × $0.29/kWh = $24,360/yr. Battery: Powerwall 3 (13.5 kW) on Eversource at $325/kW/yr. Energy cost reduction does NOT double-count TOU arbitrage. Source: EIA Jan 2026, Eversource ConnectedSolutions 2026, ACEEE 2022 consumption benchmark. [How we calculate →]
Midwest (IL / ComEd)
10-unit portfolio — annual impact
| Benefit | No Batteries | 2 Batteries |
|---|---|---|
| Energy cost reduction (8–15%, flat rate) | $1,148–$2,153 | $1,148–$2,153 |
| VPP/DR (CenterPoint IN only; ComEd no program) | $0 | $330/yr |
| Total annual | $1,148–$2,153 | $1,478–$2,483 |
Baseline: 10 units × 700 kWh/mo × $0.1707/kWh = $14,339/yr. TOU arbitrage not available on standard ComEd residential tariffs. ComEd residential rate increases driven by transmission and capacity costs. [How we calculate →]
West Coast (CA / PG&E)
10-unit portfolio — annual + one-time
| Benefit | Annual Recurring | One-Time Year 1 |
|---|---|---|
| Energy cost reduction (8–15%) | $2,548–$4,784 | — |
| VPP/DR (Renew Home, 5 enrolled households) | $1,000–$2,500/yr | — |
| SGIP rebate (2 batteries, ~$200/kWh) | — | $5,400 one-time |
| Total Year 1 ($3,548–$7,284 + $5,400) | $8,948–$12,684 | — |
| Total annual (Year 2+) | $3,548–$7,284 | — |
SGIP general budget waitlisted in most CA territories as of early 2026. Equity Resiliency available for income-qualified / fire-zone properties at $1,000–$1,100/kWh. [How we calculate →]
SGIP availability: General budget is currently waitlisted in most California territories. Equity Resiliency budget is available for income-qualified households in high fire-threat districts or areas experiencing PSPS events. Contact CPUC or your local program administrator for current availability.
Integrations
Works with the systems your team already uses.
No double-entry, no custom spreadsheets. We pull from your PMS and utility providers, and push dispatch schedules back out.
Yardi
Voyager / Breeze
AppFolio
Property Manager / Plus
Buildium
Core / Pro
Green Button Connect
utility data
Bayou Energy
utility data
Integration depth varies. Yardi and AppFolio: production connectors. Buildium: in development. Need something else? Our REST API covers the rest.
Security
Enterprise-grade posture, clearly labeled.
We hold utility credentials, tenant energy histories, and dispatch schedules for dozens of buildings. Our controls reflect that.
SOC 2 — In progress
We are actively in a SOC 2 Type I readiness engagement. We do not yet hold a signed attestation. Our control narrative and current posture is available under NDA for enterprise procurement review.
Role-based access
Owner, property manager, technician, auditor. Least-privilege by default.
Audit logs
Every dispatch, report export, and credential access retained 7 years.
Encrypted at rest & in transit
AES-256 at rest, TLS 1.2+ in transit, per-tenant key isolation.
SSO on enterprise tier
SAML 2.0 and OIDC. SCIM user provisioning on roadmap.
Pricing
Per site. Per month. Volume bands, not mystery.
A "site" is one physical building (one utility meter anchor). Multi-building parcels are priced by the building count. All tiers below are indicative — final pricing depends on deployment scope and integration work. Contact us for an RFP.
