4.1. Governance of Collaboration for a Local Sustainable Energy Ecosystem
4.1.1. Sigma—Shifting to a Local Decarbonized Gas
The gas market represents a significant part of Company E's operations, yet it faces transformations due to recent energy crises and national decarbonization objectives. Adapting to these goals, Company E must provide its customers with access to locally-sourced decarbonized gas.
The Sigma project is an anaerobic digestion (AD) system. The project originated in 2014 from a shared vision between TerraAgency, a regional public agency in the Walloon Region of Belgium, and a subsidiary of Company E specializing in large-scale biomethane initiatives. The ownership structure of the Sigma plant incorporates both private and public stakeholders. Company E holds the majority stake at 40%, followed by Durabio, a waste management company, with a 20% share. On the public side, TerraAgency owns another 20% of the shares. In 2022, CivicEco—an intercommunal funding organization representing 57 towns and municipalities in the Walloon Region—became a significant stakeholder by acquiring a 20% share in Sigma. The project's objective was to capitalize on the region's abundant plant resources by converting them into biomethane, aiming for a production output of 100 GWh based on an input of 150,000 tons per year from local farmers, agro-industrial companies and community biowaste.
Figure 2 presents all the actors involved in the AD system and their interactions.
Collaboration with TerraAgency facilitated access to a suitable project site, and final permits for biomethane injection were obtained in 2019. However, a significant challenge emerged later in the project's development concerning digestate disposal. The team encountered difficulties in finding suitable outlets for the 120,000 tons of digestate generated annually, leading to a temporary project halt. Despite initial expectations of securing agreements with local farmers, the process proved more complex than anticipated, with farmers either declining or requesting compensation for accepting the digestate. To address this issue, the project team explored options such as drying and exporting a portion of the digestate to offsite locations, necessitating modifications to the power plant's design and incurring additional costs. Additionally, they engaged a local consultant to facilitate discussions with farmers and redefine the power plant's design, incorporating a dehydration unit.
Furthermore, market conditions shifted during the project's progression, making it increasingly challenging to source the required 150,000 tons of plant-based feedstock annually. Although the project initially secured over 50% of the required volumes from a local partner named Lupota, specialized in industrial potato processing, market dynamics changed, impacting the availability of plant-only feedstock. Despite Lupota's commitment to supply 80,000 tons of potato waste under a long-term contract, unforeseen challenges arose. The collaboration aimed to enable biomethane production for Lupota's own use, with Company E purchasing the remaining 30,000 tons for external distribution. However, the agreement's anticipated benefits, including ‘green certificates’, were affected by changes in regulatory frameworks. Efforts to secure additional green certificates through lobbying the Walloon Region commenced in June 2022. Meanwhile, Durabio, poised to become a financial partner in the Sigma project in exchange for managing its biowaste, expressed concerns in 2023 regarding the quantity they could provide, posing a risk to Sigma's biowaste supply. To address this challenge, the project relied on an external digital feedstock mapping solution and renegotiated terms with Durabio.
Despite its complexities, the project benefited from robust local partnerships and institutional support, particularly from the Walloon Region. This collaboration provided crucial backing and afforded flexibility in adapting the power plant's design to overcome challenges encountered during its development.
4.1.1. Beta—Embedding Local Energy into the Wood Ecosystem
The Beta district heating (DH) system traces its roots back to 1968, and incorporates a diverse array of technologies. It was initially developed by the municipality in tandem with the waste incinerator to utilize surplus heat to heat the adjacent neighborhood. In addition to this surplus heat, the system has historically relied on supplementary boilers to meet consumer demand, particularly during winter when waste incinerator heat alone proves insufficient.
A significant evolution occurred in the 2000s, with a shift towards biomass and extensions of the network to an adjacent neighborhood. Presently, the Beta DH system is predominantly powered by the incineration plant—managed by the waste syndicate—and complemented by three biomass boilers. The first was erected in 2006, followed by two additional units in 2013.
Even though the DH system is owned by the metropolis, all boiler and distribution network operations are overseen by a private operator—HeatCo—which is a subsidiary of Company E.
Figure 3 shows the embeddedness of the DH system into a local ecosystem: despite being a global company, Company E is dependent on local actors for heat supply and the outlet.
Transitioning to biomass necessitated extensive logistical efforts, with approximately 38,000 tons of local wood supplied annually, primarily sourced from forest sites. Since 2013, WoodPro, Company E’s procurement center, has managed wood supply for the Beta biomass boilers, acting as an intermediary between HeatCo and wood-energy producers or traders. Half of the wood supply operates under long-term contracts between WoodPro, ForestEnergy, and the NationalForestCorp. These contracts prioritize the NationalForestCorp and ForestEnergy as primary suppliers, with annual purchase quotas stipulated by WoodPro, allowing for flexibility. The remaining supply is secured through shorter-term contracts, enabling WoodPro to adjust orders based on HeatCo's annual woodchip requirements.
To ensure traceability, WoodPro employs software to monitor all orders, detailing woodchip specifics such as moisture content, supplier, transporter, and origin. However, the wood-energy supply chain faced challenges in its early stages due to a lack of professionalization. Orders were processed weekly for local suppliers, requiring careful coordination of chipping machines and forest worksites to minimize transportation and optimize usage. This process involved entrepreneurs, financed by NationalForestCorp, who bore the financial burden until woodchip delivery and quality inspection.
To support the sector's development, the region implemented a wood masterplan, advocating for long-term contracts to enhance traceability and secure partnerships. WoodIndustryAssoc, the interprofessional organization for wood in Franche-Comté, views wood energy as a vital supplementary revenue stream for the wood sector, complementing core activities and providing an outlet for waste wood. Furthermore, the combustion residues find utility in various local industries and agricultural applications, such as composting and purification.
The transition from a DH system based on fossil fuels to one based on biomass proved complex. Securing a reliable and cost-effective biomass supply necessitated significant sector restructuring, a feat made possible by Company E's commitment to long-term supplier contracts.
4.2. Governing the Interdependencies—Securing Collaboration
Our analysis of AD and DH systems shows that the local embeddedness of the two systems has become predominant over time. Going local has become part of the strategy, desired by customers. In Beta DH, the securing of local biomass resources to control the prices was a cornerstone of the project. Globally, DH needed to play a role in local development. The local authority stated that “work on communication, jobs and energy poverty have been integrated into the new contract as mandatory requirements.” Similarly, in biomethane projects, Company E had to prove the creation of local value and services to the community to enhance accessibility. Indeed, for the Sigma project, the enrolment of the industrial partner was a consequence of “the preference for a more local and circular solution to treat their biowaste, which was initially valorized in the Netherlands” as indicated by a TerraAgency director. Furthermore, both local energy projects participate in the local energy sovereignty. Apart from these two cases, a DH expert in Company E stated that “customer demands are changing completely: they want to be more committed and t make sure that the projects are going to have a positive local impact.”
To better deliver the local value proposition, Company E had undertaken several reorganizations, each intended to help the company become more locally embedded, and to build a presence in specific geographic areas. An interviewee from the Strategy Department explained that “we need to strengthen our presence in strategic geographic areas.” Specifically, a development manager explained that “we tried to cover the territory by decentralizing the agencies and distributing the teams over multiple locations to stay closer to the territories.”
Both of the analyzed projects are embedded in a complex local ecosystem with which it interacts at various levels. First, to implement or operate an LES, Company E sets up a long-term contract with local actors (the public service delegation with the public authority in the case of DH, and a shared ownership of the operating company with regional public actors in the case of AD). Second, to secure the project value chain, from its local energy inputs to its local clients, Company E shapes and secures an energy ecosystem around its project or integrates an existing one. Such embeddedness necessitates a governance of collaboration.
Table 3 summarizes the characteristics of the governance in both projects according to the criteria adapted from [
35]. We focus here on the second level of local embeddedness, as the long-term contract with a local actor is mostly a formal arrangement enabling further collaboration with the ecosystem. In the case of DH, this contract is a Public Service Delegation between a public authority (the metropolis of Beta) and a private operator (Company E). In Sigma, the contract addresses the issue of green certificates serving as a crucial incentive for renewable energy production. While the initial agreement with Lupota aimed to secure green certificates, challenges in obtaining them prompted Company E to engage in advocacy efforts with regional authorities. This collaborative approach underscores the importance of regulatory support in facilitating the transition to sustainable energy systems at the local level.
In both cases, the governance characteristics are closer to a lead governance [
38]. In the case of Beta, the purchase center takes a delegated lead on managing the interdependencies between the DH network and the wood-energy sector, by acting as an interface between the two and acting as the DH delegate during negotiations. Within the wood-energy sector, coordination is needed to ensure the proper structuration of the sector and its interface with other wood uses. In the case of Sigma, the collaborative governance model is exemplified by the co-development partnership between TerraAgency, a local public development agency, and Company E's subsidiary in Belgium. The collaborative approach facilitated access to suitable project sites, regulatory framework development, and stakeholder engagement. Furthermore, other local entities such as CivicEco and Durabio are active in the governance of Sigma, contributing financially to the structure. Durabio’s collaboration goes beyond financial contribution, as the company is engaged in procuring local biowaste. Similarly, Lupota agreed to provide its local by-products in exchange for the local biomethane produced by Sigma. As stated by the business developer of the Sigma project
“we work on keeping them informed, organizing recurrent meetings.”
The collaborative approach is characterized by the use of securing mechanisms, like long-term contracts and financial participation, which ensure a governance of the interdependencies. These arrangements secure the ecosystem and participate in value sharing between the stakeholders. They also facilitate the governance by making the collaboration more formal: Once the contract is negotiated, there is limited need for network work (trust building, alignment, involvement, etc.). However, creating this governance contract requires resources and competencies. In the case of DH, there was for instance a need to agree on the right indicators and units to account for the input wood (weight, energy, etc.), as well as the monitoring mechanisms for these indicators (before drying, after drying, before combustion, etc.). These competencies need to be developed by all stakeholders involved in such local energy projects.
For Company E, such an approach by projects created the need for new competencies. Specialists from the company confirmed that while having historical technical expertise in the gas industry, developing local biogas solutions constituted a challenge. Compared with the conventional gas activities Company E had, developing local biogas plants or sustainable DH systems was very context-specific. For biogas, it required in-depth knowledge of the local ecosystem—e.g., gas networks, inputs such as agricultural, agro-industrial, or biowaste flows, roads for logistics—to select the right plot of land and develop the plants there. Both projects rely on very local technical and natural resources, but the human resources—workforce and key partners (suppliers, funding agencies, etc.)—are also local.
4.3. Governance of Collaboration—Securing Collaboration
Our analysis shows how Company E had to participate in a governance of collaboration to set up a local energy system. This type of governance helps to ensure the success of its SBM and supports the creation of local value.
Figure 4 shows our adaptation of Bocken and Gerardts’ representation of drivers for SBMI [
10], highlighting the governance mechanisms that could support the operationalization of local SBMs.
A strategic focus on local ecosystem building and securing.
Bocken and Geradts [
10] highlighted the importance of collaborative innovation instead of focusing on functional strategy. We go one step further, pointing out that such collaboration goes beyond a company’s boundaries as there is a need to manage interdependencies with the ecosystem and engage in cross-sector innovation. A strategic focus on building up and securing the local ecosystem facilitates the implementation by companies of sustainable projects and their supporting SBMs.
Operational drivers to govern local collaboration
This governance of collaboration leads to a change in operational procedures. Short-term contracts will be challenged by the need for long-term contracts securing the ecosystem. The functional expertise and its metrics will face the local expertise-building and co-construction of relevant metrics. Moreover, new internal expertise will be required. To work with the local ecosystem, Company E had to create specific competencies in the making of local projects, also defined as “territorial knowledge” by Sigma’s business developer. For instance, they have developed expertise on financing projects using regional funds. At the group level, the R&I department of Company E also designed tools to help embed their activities locally: a mapping tool to obtain an overview of the local ecosystem; a reporting tool to measure the impact of a project at the local level, etc. They also work on developing and improving their market intelligence regarding the local resources available.
Beyond the company scope—the role of public policies and the regulatory context
Recognizing the local ecosystem as a driver for SBMI means that companies acknowledge its interdependencies with local actors. To facilitate the management of such interdependencies, the local policy and regulatory context play a significant role. Supportive policy environments, such as incentives for renewable energy deployment and mandates for waste management, provide companies like Company E with the necessary framework to pursue local energy solutions. By aligning with local policy objectives and regulatory requirements, Company E navigates regulatory complexities and leverages policy incentives to drive SBMI. The working group on DH and cooling innovation published an internal communication summarizing all the innovations for public service delegation, and how Company E could set up new structures integrating the public authority in the governance of the DH operating company. Similarly, in the Sigma Project, Company E benefited from TerraAgency being part of the working group on biomethane green certification. As stated by the director of the public agency “there was a support mechanism that was to be put in place and this support mechanism was not clear. So, we took the initiative and made a proposal based on the Sigma project. Finally, this proposal was retained by the government.”
