Design & Feasibility Assessment

Identify Lead with Potential for ESI Program.

Selected Communication Method Between Uplight & OEM (Sponge) has been pre-tested and confirmed.

Consider leveraging a feasibility study subsidized by BC Hydro to assess project viability.

>200,000 kWh/Year OR 100kW Demand Impact = 100% Funded

<Above Criteria = 50% Funded

Review battery options which are compatible with both the ESI program and the constraints of the site.

ESI Workbook
To be filled out during initial screening.
ESI Vendor Connection Form
To be filled out during initial screening — this is where you specify that you are using Sponge as your "system integrator" to receive and execute battery deployment calls from BC Hydro's DERMS.
ESI Connectivity Guide & ESI Participant DERMS Connectivity Request Form
Fill this form once your battery has been ordered to begin coordinating post-installation & commissioning DERMS connectivity tests with BC Hydro.
BESS Best Practices
Pay special attention to Section 7 which outlines BC Hydro's battery design protocols for various building types. Should be carefully reviewed during the feasibility study process. Check if your proposed system requires a Hazard Mitigation Analysis.
