Data & optimization

Leverage data to maximize the ROI of every site

ClearSky integrates market, utility, incentive, and site data to screen candidates, model the full value stack, and rank opportunities — so capital goes to the sites with the strongest risk-adjusted return.

Value-stack optimization — aggregate SDVPP, injection, offtake & host value.
Portfolio prioritization — compare sites for investment and capital allocation.
Program & incentive matching — surface the rebates and tariffs each site qualifies for.

Procurement marketplace

Source, contract, and aggregate the value stack

ClearSky is building the marketplace layer for project procurement — connecting developers to equipment, materials, and contracts, and aggregating demand to optimize pricing and terms across the value stack.

Materials & equipment sourcing — connect projects to vetted supply.
Contract & demand aggregation — pool volume to optimize pricing and terms.
Value-stack aggregation — bundle revenue streams across a portfolio of sites.

Who it's for

Built for the teams that develop energy at scale

ClearSky serves the organizations moving distributed energy, DER, and data-center projects from origination to operating asset — wherever internalizing development, permitting, and procurement creates the most value.

An active portfolio across Illinois and PJM

ClearSky develops and manages a growing portfolio of distributed energy assets — battery storage, EV charging, microgrids, and micro data centers — spread across wholesale market participation, grid injection, data-center offtake, and behind-the-meter value. Each site is evaluated, packaged, and monetized through the OMEGA platform.

480 kW charging, SDVPP & PJM frequency regulation

ClearSky's Fulton, Illinois site pairs a battery energy storage system with 480 kW of DC fast charging — delivering high-power charging without triggering a costly utility service upgrade. The same battery is enrolled in ComEd's Smart Distributed Virtual Power Plant program and injects into PJM's frequency regulation market, stacking three revenue layers on a single asset.

Backup Generation & Energy Offtake Site-host lease

Where ClearSky is headed

Microgrids & micro data centers powered by energy arbitrage

ClearSky's core thesis: co-locate battery storage with distributed compute to build self-contained microgrids that buy energy when it's cheap, serve compute continuously, and sell capacity and regulation back to the grid when it's valuable. Energy arbitrage funds the compute; the compute anchors the load; the grid services stack on top. It's a battery-first model that doesn't depend on solar and turns every site into a dual-purpose energy node and edge data center.

Development across every asset class

Behind every project is the same end-to-end capability: ClearSky evaluates and develops BESS, EV charging, microgrid, and micro data center opportunities — determining whether a site is viable, financeable, permittable, and capable of generating grid or behind-the-meter value.
