Extensible Energy Introduces HardCap, a Demand Charge Elimination Feature for Small Commercial Solar

DemandEx’s latest software update now includes HardCap™, a feature that allows small commercial solar buildings to cap demand spikes and qualify for a lower-cost utility rate.


BERKELEY, Calif. Jan. 13, 2020 – Extensible Energy has released new features for DemandEx, its award-winning demand charge reduction software that works without energy storage. The most notable improvement is HardCap™, an intelligent algorithm that automatically blocks demand spikes over a pre-set kilowatt level. When enabled, HardCap allows small solar PV buildings to limit demand spikes and qualify for an energy-only utility rate, saving thousands of dollars for demand charges while improving solar ROI.


With DemandEx’s standard configuration, the software intelligently monitors solar and building loads and finds ways to reduce demand charges by about 30%. In many utility service territories, with HardCap enabled, DemandEx 100% eliminates demand charges through an enhanced whole-building load and solar PV output monitoring that is programmed to curtail usage whenever total electrical loads exceed the utility’s pre-defined demand threshold.


For example, many utilities require a customer to pay monthly demand charges if demand exceeds 100 kW in any of the preceding 12 months. Even with an appropriately sized solar array, a cloud could create an unavoidable demand spike, authorizing demand charges for the next 12 months. When DemandEx’s HardCap feature is enabled, total demand is always capped below the 100kW limit, allowing the building owner to qualify for a tariff with no demand charges.


For larger buildings that routinely exceed the utility’s demand charge rate threshold, DemandEx’s normal load-flexibility algorithms can still automatically reduce demand charges by about 30% in commercial solar buildings. No batteries required.


John Powers, CEO of Extensible Energy, said, “We developed HardCap because our commercial solar installation partners told us about relatively small commercial PV buildings that rarely went over the utility’s demand threshold, yet still triggered thousands in annual demand charges. HardCap is for those customers. It’s not for every solar PV building, but when it fits, the savings are tremendous.”


In addition to HardCap, Extensible Energy has also released a new DemandEx web dashboard that gives solar installers the ability to view data from multiple DemandEx solar projects. Users can now create and save their own custom views, see load flexibility actions that DemandEx is performing in real-time, and get access to additional support and resources for their sites.


“Our new Dashboard is vital for our large partner installers and developers,” said Powers. “It ensures that they’ll be able to easily monitor and control thousands of DemandEx buildings without any performance constraints. While these are significant improvements, DemandEx pricing remains the same, making demand charge reduction software more valuable to our solar partners and their asset owners.”
