Microgrid and Zero-Export Controls 

Individual assets typically include controls designed to operate and protect that specific equipment. 

A battery BMS protects the battery. A PCS controls power conversion. A generator controller operates the generator. A solar inverter manages solar production. 

HECSYsmart® operates above those individual systems at the facility level. It can coordinate facility demand, batteries, generators, solar, wind, thermal storage, controllable loads, switchgear and utility conditions so the assets respond together according to one operating strategy. 

The equipment controls the equipment. HECSYsmart® controls how the facility uses the equipment.

Many microgrid controllers are supplied as part of a specific equipment package or designed primarily around a predefined group of assets. 

HECSYsmart® is designed around the facility and its operating objectives. 

The platform can integrate supported equipment from different manufacturers and coordinate those assets with facility loads, electrical infrastructure, utility requirements and financial strategies. 

The objective is not merely to keep a microgrid running. The objective is to continuously decide how the facility should use its available energy resources. 

No. 

HECSYsmart® is designed as an equipment-agnostic integration and control platform, subject to the communications and control capabilities of the equipment being connected. 

This allows battery storage, generators, solar, wind, thermal storage, meters, switchgear and other controllable systems to be evaluated based on what best fits the facility rather than forcing the entire project into one proprietary equipment ecosystem. 

Zero export means the facility is controlled so onsite generation does not intentionally send power back onto the utility grid beyond the established operating limit. 

HECSYsmart® can monitor facility load and available generation in real time and coordinate supported batteries, generators, solar and controllable loads to maintain the required grid-import or export condition. 

The exact control strategy depends on the utility requirements, interconnection agreement and electrical architecture of the facility. 

No. 

Zero-export requirements and grid participation are different operating conditions. 

A facility may be required to prevent export during normal operation while still qualifying for approved demand-response, load-reduction, capacity or other grid programs. 

Where the utility, interconnection agreement and market rules allow it, HECSYsmart® can support different operating strategies for different grid conditions. 

Zero export when required. Grid interaction when permitted.

No. 

A microgrid can incorporate different combinations of distributed energy resources depending on the facility. 

HECSYsmart® can coordinate supported generators, solar, batteries, wind, thermal-energy storage and controllable facility loads. 

Battery storage can add significant flexibility, but the operating architecture should be designed around the actual facility requirements rather than assuming every project requires the same asset mix.

That depends on the facility electrical architecture and the assets available. 

Where the system is designed and approved for islanded operation, HECSYsmart® can coordinate supported generation, storage, switchgear and facility loads according to predefined outage and restoration sequences. 

Critical loads, reserve capacity, operating limits and reconnection procedures are established during engineering and commissioning.

Yes. 

HECSYsmart® automation operates within approved permissions, equipment limits and operating sequences. 

Facility personnel can retain the appropriate local controls, manual overrides and operating authority required for their operation. 

Automation is intended to manage routine energy decisions without removing necessary operator control.

Yes, where supported communications and control interfaces are available. 

This is one of the fundamental advantages of a facility-level control architecture. 

HECSYsmart® can evaluate conditions across multiple assets before making a control decision rather than allowing each asset to optimize itself independently. 

A battery may charge while solar production is available, remain reserved for resilience, discharge for a demand event or coordinate with generation depending on the facility’s priorities at that moment.

The same controllable energy capacity used for facility operations may also have value to the grid. 

Depending on the market and utility territory, opportunities may include demand response, capacity programs, energy-market response, peak management or other grid services. 

HECSYsmart® is designed to coordinate those opportunities around the facility’s primary operating requirements. 

The facility remains the priority. Available flexibility becomes the opportunity.

HECSY evaluates more than equipment cost. 

The analysis can consider utility tariffs, demand reduction, outage exposure, operational risk, available generation, capital requirements, energy-market opportunities and the expected performance of the integrated system. 

Measured information, assumptions and projected outcomes should remain clearly separated. 

The question is not simply: “What will the microgrid cost?” 

The more important question is: “What operational and financial value can this facility create from the assets it already has — and the assets it may add?” 

A generator can produce power.

A battery can store it.

Solar and wind can generate it.

Thermal storage can shift it.

Switchgear can route it.

HECSYsmart® determines how those resources should work together.

That is how distributed equipment becomes a microgrid — and how a microgrid becomes an intelligent facility energy asset.
