Behind-the-Meter Flexible Compute for Utility-Scale Renewables
Monetizing Stranded Power.
Stabilizing the Grid.
Porter/Collins builds Active Dispatchable compute loads that co-locate behind the meter with utility-scale solar and battery storage. We transform curtailed daytime generation into predictable revenue — while perfectly protecting your capacity payments.

The Problem
The Decoupling Crisis
Solar and battery storage are the Swiss Army knife of the modern energy transition. Every grid that scales them runs into the same structural wall.
Generation is being built faster than transmission can be upgraded. Interconnection queues stretch years deep. The result is the now-familiar duck curve: massive midday solar surpluses with nowhere to go, followed by a steep evening ramp that strains the same grid the surplus could not relieve.
Across mature solar markets — CAISO, ERCOT, Iberia, the Australian NEM, and the fast-scaling LATAM and MENA grids — operators are watching utility-scale solar plants curtail GWh-by-GWh and clear at zero or negative prices during the very hours those assets were built to monetize.
Capital deployed against generation is producing zero marginal revenue during the windows it was designed for. Waiting for transmission upgrades is a multi-year horizon that bondholders, sponsors, and asset rotation funds cannot accept. The supply/demand mismatch is a permanent feature of solar-led decarbonization, not a transient growing pain.

The Solution
A Co-Located, Behind-the-Meter Asset
— Engineered for Every Grid
Porter/Collins deploys flexible compute infrastructure directly behind the meter at utility-scale solar and BESS sites. By sitting inside the host facility's point of interconnection, our consumption is structured as self-supply — never traversing the public grid, never triggering systemic withdrawal events, and never competing with the host's grid-bound dispatch.
Behind-the-Meter Topology
A single point of connection shared with your solar and BESS. Our consumption is private-wire by design and never appears on the system operator's withdrawal ledger.
Self-Supply Framework
We operate within each jurisdiction's behind-the-meter and self-supply rules — engaging the local TSO, ISO, or regulator early and structuring our load to fit cleanly inside existing flexibility frameworks.
Universally Deployable
The model works wherever solar generation outpaces transmission — from CAISO and ERCOT to the European interconnections, the Australian NEM, and the LATAM and MENA build-outs. Same physics, same arbitrage, same capacity discipline.
“A behind-the-meter compute load is the only structurally clean way to monetize curtailed solar without putting the host's capacity revenues at risk.”
Operations
Sub-Millisecond Load Shedding.
Zero Capacity Cannibalization.
Settlement-Aligned Arbitrage
Mapped to the system operator's settlement intervals
Our control system maps power draw to the host market's settlement intervals — whether that's 5-minute, 15-minute, or 30-minute resolution. Algorithmic load shedding executes in sub-millisecond response time, allowing the asset to consume only when curtailed energy is genuinely available — never displacing grid-bound generation, never creating an unscheduled withdrawal.
- Real-time integration with the system operator's dispatch signal
- Sub-millisecond load curtailment on price or signal
- Auditable per-interval consumption logs
The Capacity Guarantee
Scheduled Hard Shutoff: Evening Net-Peak, Daily
We execute a scheduled hard shutoff during the grid's evening net-peak window every day. By curtailing our load to 0 MW from 18:00 to 22:00 local time, we guarantee zero cannibalization of the host's capacity market revenues. Your BESS dispatches 100% to the grid when the system needs it most — exactly when capacity payments clear.

Partnership Model
Zero CAPEX.
Asset Rotation Ready.
Porter/Collins offers a zero-CAPEX structure for generators. We sign a behind-the-meter PPA for the daytime solar production that would otherwise be curtailed, deploy and operate the compute infrastructure on our own balance sheet, and pay the host a fixed off-take regardless of spot conditions.
The hybrid SPV gains a predictable, contracted revenue floor on previously stranded production. That floor flows directly into the asset's discounted cash flow model, boosting Enterprise Value and bankability for institutional exit sales — the core thesis underpinning every asset rotation strategy in the global renewables space.
No additional capital. No lender consent risk on grid usage. No cannibalization of capacity revenues. Just a cleaner SPV cash flow profile and a more bankable exit — wherever your assets sit.
What the host gets
- Zero capital outlay required from the host
- Fixed off-take on otherwise curtailed daytime hours
- Improved Enterprise Value on hybrid solar + BESS SPVs
- Highly bankable for institutional asset rotation exits
Compliance & Grid Safety
Built to Strengthen the Grid,
Not Stress It
Porter/Collins is engineered as a grid-stabilizing asset. Our regulatory, safety, and ESG commitments are designed to meet the institutional thresholds of Tier-1 sponsors, lenders, and asset rotation buyers — in every jurisdiction we operate.
Code-Compliant Electrical Infrastructure
Every Porter/Collins deployment meets international electrical safety standards — including arc-fault protection (IEC 62606 / NEC AFCI) and the current ground-fault and isolation requirements for the host jurisdiction.
Grid-Forming Inverter Compatible
Our integration model supports partner BESS facilities running grid-forming inverters that improve local voltage and frequency stability — strengthening the grid we share, not stressing it.
Local Grid Security First
Operational protocols are designed around the host system operator's reliability standards, worker safety, and full transparency. Every shutoff, every dispatch, fully auditable.
