Renewable Energy Communities (CER) for Industrial Areas: a guide for companies in Apulia
In Apulia, industrial areas (ASI) and manufacturing districts represent the ideal ecosystem for the energy transition. Here, where the concentration of ASI areas and ZES zones is among the highest in Southern Italy, we often face an infrastructure paradox: logistics warehouses with thousands of square meters of unused rooftop space sit next to energy-intensive industries that, due to structural constraints, have no room for their own photovoltaic systems.
Until recently, this imbalance was a technical limitation. Today, thanks to the regulatory framework for Renewable Energy Communities for businesses (RECs), it becomes an opportunity for collaborative business models.
However, reducing a REC to a mere incentive mechanism is short-sighted. For an industrial consortium or a group of companies, a REC is first and foremost a tool for territorial governance: it helps stabilize long-term energy costs and turns the industrial area into a self-sufficient, attractive energy hub for new investors.

“Industrial condominium”: legal and operational aspects
It is essential to clarify a regulatory point from the outset: there is no specific law for “industrial RECs” that differs from the one governing residential or mixed RECs. The legal framework is the same; what changes dramatically are the energy volumes, load profiles, and governance models.
In an energy community within an ASI industrial area, energy sharing is virtual. No new private cable ducts are required. Participating companies must be located within the perimeter served by the same primary substation (the high/medium-voltage substation that supplies the geographical area). In Apulia, ASI areas are often served by a single primary substation, which makes the connection of dozens of neighboring companies technically feasible.
The operational mechanism works as follows:
- Company A (producer) injects energy into the grid.
- Company B (consumer) withdraws energy from the grid in the same hourly time slot.
- The GSE recognizes this simultaneity and grants a financial incentive on the shared energy, rewarding “zero-mile” consumption that reduces the burden on the national transmission network.
Competitive advantages: beyond simple incentives
Setting up a REC in an industrial area in Apulia should be understood as a territorial competitiveness strategy.
Hedging and cost stability: in a volatile market, a REC works as a hedging tool. Companies can internally agree on a price for the energy exchanged, partially decoupling themselves from the unpredictable fluctuations of the PUN (Single National Price).
Real estate asset value creation: companies with large rooftop surfaces (logistics, large-scale retail) can turn unproductive areas into income-generating assets, becoming virtual energy suppliers for the district. For older systems, interesting opportunities emerge for industrial photovoltaic revamping to maximize transferable production.
ESG rating and access to credit: participating in a REC can tangibly improve a company’s sustainability profile (ESG). For banks and institutional investors, this is an indicator of lower risk and long-term vision, making access to credit easier.
The economic model: premium tariff and PNRR variables
The business plan of an industrial REC is based on cash flows that must be carefully estimated:
- Premium tariff (20-year incentive): on virtually shared energy, the GSE grants a premium tariff. Technical note: the value is not fixed; it varies depending on the plant’s capacity and the zonal energy price. This is a 20-year revenue stream that represents the community’s “cash engine”.
- PNRR grant (pay close attention to the territorial constraint): for RECs established in municipalities with fewer than 5,000 inhabitants, a non-repayable grant of up to 40% is available.
Operational warning: many industrial areas located in major Apulian cities (Bari, Brindisi, Foggia) fall within municipalities above this threshold and are therefore excluded from the PNRR grant. However, they are fully eligible for the 20-year premium tariff, which—given industrial-scale volumes—is often the most economically significant component, delivering a competitive ROI compared to other investment options.
How to set up a REC in an industrial area (roadmap)
For companies located in industrial hubs, the process requires precise formal steps. Improvisation during the setup phase can lead to future decision-making deadlocks.
Phase 1: Load profile analysis: Southenergy analyzes quarter-hourly load curves. Synchronization is essential: if everyone consumes when no one produces, the incentive is zero. In such cases, the integration of storage systems is evaluated (learn more about the use of industrial BESS solutions).
Phase 2: Establishment of the legal entity: the REC is an independent legal entity (typically an unrecognized association, a cooperative, or a foundation). The bylaws must be “open”, clearly defining rules for the entry and exit of members (companies).
Phase 3: Internal regulations (the core of the system): this is the private agreement that defines how incentives are shared. Who invested in the generation assets? Who only contributes consumption? The regulations translate these differences into economic shares.
Phase 4: GSE accreditation: once established, the qualification process on the GSE portal is managed in order to unlock incentive payments.
Prosumer vs consumer: defining roles within the consortium
Within an industrial REC, different roles coexist. Understanding your role determines the expected economic return.
- Prosumer (producer–consumer): a company that owns a photovoltaic system and consumes part of the energy produced. This role delivers the highest benefit: direct savings on the energy bill plus a share of the incentive on the energy that is virtually shared.
- Producer (producer only): a company (or third-party investor) that provides the photovoltaic system and rooftop space. Revenue comes from selling the energy produced and from the incentive share earned by making the asset available.
- Consumer (consumer only): a company without space for generation assets that joins the REC to consume energy virtually. It incurs no CAPEX (investment costs) and receives a share of the incentives, reducing operating costs.

FAQ – Frequently Asked Questions
Yes, and this is the most technically efficient role (Prosumer). The company physically self-consumes as much energy as possible (maximizing savings) and shares any surplus with the grid. This mix optimizes the overall financial and economic plan.
At least two distinct members (with different VAT numbers) connected to the same primary substation are required. Generation plants must be newly built (commissioned after the establishment of the REC or, under transitional rules, after 16/12/2021) and each plant must have a capacity not exceeding 1 MW.
There is no rule imposed by the GSE. Allocation is freely decided by the members within the Internal Regulations. Typically, priority is given to those who made the investment (to recover CAPEX), while a portion is allocated to pure consumers as an incentive to participate. Clarity in these rules is essential for the long-term stability of the REC.
