Electrical estimating with a wider perspective.

Clarity for renewable energy construction costs.

Connecting electrical scope with context to inform cost decisions before the build.

Renewable Energy System Estimation

Turn system requirements into installed scope.

Battery Energy Storage

Connect the AC delivery requirement to the battery nameplate, PCS blocks, auxiliary loads, and the choice between initial overbuild and later augmentation.

Solar Photovoltaics

Translate DC and AC ratings into modules, racking, inverters, and collection. Account for pile refusal, terrain, trench routes, and who furnishes the equipment.

Substation & Interconnection

Follow MV collection through the project substation and gen-tie to the point of interconnection. Define the work the project owns and the work the utility performs.

Scope Connections

Following the power path from system equipment to the grid.

Each connection represents installed quantities and an interface that needs an owner.

Conceptual solar and storage export pathA PV array exports through its inverter and MV transformer. The battery can both export and charge through its PCS, MV transformer, and the main transformer. The branches meet at MV collection, then connect through a circuit breaker, Gen-Tie, revenue metering, and the point of interconnection to the utility grid.

Why a unit rate is only a starting point

The same rating can require a different construction scope.

Pile refusal on one site. A longer gen-tie on another. A constrained substation at the point of interconnection. The estimate needs to explain those differences before the budgets can be compared.

Professional Profile

Construction, utility, and portfolio estimating.

Electrical construction estimating, utility-side interconnection experience, and utility-scale PV and storage estimating. Three perspectives on the same question: what does it take to build and connect the project?
