Green Charge Networks is introducing the world's first commercial demand charge reduction battery system called GreenStation to help commercial and industrial electric ratepayers to save on their monthly bills.
The GreenStation works just like a micro-scale peaker plant using lithium ion batteries. During high peak demand times, utilities charge a premium (per kW) called "demand charges." These charges get added to the energy portion (per kWh) of a customer's total electricity bill. GreenStation pumps out energy during the spikes in energy consumption and recharges during the lulls. Unlike utility-scale peaker plants, which are dirty, petroleum-based sources, GreenStation uses an advanced energy storage medium that is clean, green, environmentally-friendly, and far less expensive.
Demand charges are becoming a substantial portion of electric ratepayers' bills, sometimes as high as 70% of the overall monthly bill, depending on the loading pattern. Meanwhile, the fees assessed on demand charges in $ / kW have been dramatically rising in the more expensive markets by 10+% per year over the past 5 years. GreenStation is the first commercial offering to target this challenge.
We offer our product through a Power Efficiency Agreement℠ or PEA℠, to eliminate the upfront cost burden and to deliver pay-for-performance on demand reduction.
In the solar PV industry, to get the best return on investment on an installation, you have to control the tarriff schedule that the customer is on.
Energy storage can help!
By shaving off the top of the highest demand peaks, batteries can keep the customer's peak demand usage under a certain threshold (e.g., 20 kW, 200 kW, 500 kW, depending on what rate the customer is on) to allow solar developers and integrators to install solar PV on the best possible rate for the customer, giving them the best ROI for the solar PV system.
By installing a battery, and getting the customer onto the "solar-friendly" utility rate schedule, the total system not only gets favorable tariff rates, but it reduces energy usage (kWh) as well as demand charges (kW). Ask us about our PEA℠ pay-for-performance structure to complement solar PPA.
