Peak Shaving for Demand Charge Management
Solar-plus-storage with peak shaving strategy provides savings opportunities where there are demand charges and TOU pricing in the electricity tariff structure.
Peak shaving provides double savings where peak load coincide with electricity price peaks.
ROSEC Solar provides engineering services for designing high-ROI behind-the-meter solar-plus-storage solutions for Commercial and Industrial facilities.
Let’s devise strategy for reducing your max demand charges. Just share your electricity bill and the load profile of your facility. We will design and deploy a cost-effective PV-plus-storage.
The controller uses an adaptive control algorithm that calculates the target power needed to shave the peak load and at the same looking at the battery state-of-charge. The controller will never shave the smaller peaks and leaving the bigger peak intact. The controller tracks the running month peak and does not shave a peak lying below it.
The Dispatch Strategy makes effective use of the battery that reduces grid power purchases by managing the interplay between the available PV power and electric load.
We use REopt, SAM and other optimization tools for designing the PV-BESS system for the historical load profile, optimizing the peak demand reduction, and quantifying the potential savings.

Maximizing Self-Consumption
It is vital to analyze costs and benefits and ensure profitability of investment in facility-scale PV+BESS for BTM applications.
Self-consumption needs a different strategy to optimize the size of the PV array and the battery capacity. ROSEC Solar provides economic sizing of the PV array and storage capacity for maximizing self-consumption and where maximum profit is ensured.
For a PV plus DC-coupled system, the battery is sized for the storing the excess solar generated energy. The system value is maximized by using an optimum DC/AC ratio and at the same time taking benefit of time-of-use utility rates during peak hours. And using a storage topology that qualifies for maximum value of available incentives like tax credits!
A control algorithm is always implemented for charging/discharging strategies and optimal operation of the system.
Maximizing the share of self-produced energy is ideal for regions with greater PV penetration and where storage is mandatory for interconnection approval. It also provides energy independence, resilience and security.
We use PVsyst, SAM, REopt and some other tools to validate our designs and financial profitability.
