A Strategic Solar-Plus-Storage Acquisition
Alight has acquired a utility-scale solar and battery storage project in Kalundborg from GreenGo Energy, marking its first fully integrated solar-plus-storage development in the Danish market.
The acquisition represents a strategic entry into Denmark’s hybrid energy segment, as Alight continues to expand its presence across the Nordic region. By adding a combined solar and storage asset to its pipeline, the company is aligning its development strategy with the increasing demand for flexible, dispatchable renewable energy solutions.
The project combines a 79 MWp solar photovoltaic park with a co-located 55 MW battery energy storage system (BESS), forming a hybrid energy platform capable of delivering both generation and grid-balancing capabilities. This dual-function approach allows the asset to operate more dynamically within the power system, responding to fluctuations in supply and demand.
Across Europe, such hybrid configurations are gaining traction as grid operators and market participants adapt to higher shares of intermittent renewable energy. By integrating storage, developers can reduce curtailment, improve energy utilization, and create additional revenue streams through ancillary services and energy arbitrage.
For Alight, the transaction also strengthens its competitive positioning by diversifying its asset base and enhancing its ability to deliver more sophisticated energy solutions to commercial and industrial customers. It reflects a broader shift within the renewable energy sector, where value is increasingly derived not only from generation capacity but also from flexibility and system integration.

Project Design and Energy Output
The Kalundborg project will be developed across approximately 90 hectares and is expected to generate around 95 GWh of electricity annually, contributing to Denmark’s renewable energy supply while supporting industrial energy demand.
A central feature of the project is the co-location of solar generation and battery storage behind a single grid connection. This integrated design enables electricity produced during peak solar generation periods to be stored and dispatched later, allowing for effective time-shifting of energy supply.
This capability is particularly valuable in markets with fluctuating electricity prices, where the ability to store energy and release it during peak demand periods can significantly enhance revenue potential. It also allows the project to participate more actively in balancing markets, providing grid services that support stability and reliability.
In addition to improving financial performance, the hybrid configuration enhances overall system efficiency by reducing energy losses associated with curtailment. By ensuring that more of the generated electricity is utilized rather than wasted, the project maximizes output relative to installed capacity.
The integration of battery storage also enables more predictable power delivery, which is increasingly important for corporate off-takers seeking stable and reliable energy supply. This makes the project well-suited for long-term power purchase agreements, where consistency and reliability are key considerations.
Early-Stage Development with Strong Return Potential
The project is currently in an early stage of development, with land lease agreements secured and zoning and environmental permitting processes underway. Alight and GreenGo Energy will continue to collaborate through the development phase until the project reaches ready-to-build status, which is expected by 2028.
Despite its early-stage status, the Kalundborg project has been identified by Alight as one of the most attractive opportunities within its Danish pipeline, which includes approximately 7 GW of evaluated projects. The site stands out due to its strong return potential, supported by a combination of favorable solar irradiation, optimized layout, and advantageous land and grid conditions.
These factors are critical in determining long-term project viability, as they directly influence both generation output and cost efficiency. Access to suitable land, proximity to grid infrastructure, and favorable regulatory conditions all contribute to reducing development risk and improving overall project economics.
From an investment perspective, early-stage projects such as Kalundborg offer opportunities for value creation through design optimization, cost management, and strategic structuring of offtake agreements. This flexibility allows developers to refine project parameters to maximize returns ahead of construction.
As competition for high-quality renewable energy sites intensifies, projects that combine strong technical fundamentals with favorable market conditions are likely to attract increased interest from investors. The Kalundborg development reflects this trend, positioning itself as a high-potential asset within Alight’s growing Nordic portfolio.

Commercial Strategy: Long-Term PPAs
The project is expected to be structured around long-term power purchase agreements (PPAs), under which Alight will retain ownership and operational control of the asset while supplying electricity directly to commercial and industrial customers at pre-agreed, fixed prices.
This approach provides a high degree of revenue visibility over the life of the project, which is critical for capital-intensive infrastructure assets. By locking in long-term offtake agreements, Alight can reduce exposure to wholesale electricity price volatility, thereby stabilizing cash flows and improving the overall financial profile of the project.
For lenders and investors, such contracted revenue streams significantly enhance project bankability. Predictable income reduces perceived risk, enabling more favorable financing terms and potentially lowering the cost of capital. This is particularly important in renewable energy projects, where upfront investment is substantial and long-term returns depend on consistent performance.
From the perspective of corporate offtakers, PPAs offer a strategic tool for managing energy costs and securing long-term supply. Fixed-price contracts provide protection against market fluctuations, allowing companies to better forecast operational expenses. At the same time, access to renewable energy supports corporate sustainability commitments and aligns with increasingly stringent regulatory and reporting requirements.
The structure also allows industrial customers to directly link their energy consumption to renewable generation, strengthening traceability and enhancing the credibility of their decarbonization strategies. This is becoming an increasingly important factor as stakeholders demand greater transparency around energy sourcing.
More broadly, the growing adoption of PPAs reflects a structural transformation in energy markets. As government subsidies for renewable energy decline, private-sector demand is emerging as a primary driver of project development. Corporations are increasingly acting as anchor customers, enabling developers to bring new capacity online without relying on public support mechanisms.
Strategic Partnership and Nordic Expansion
GreenGo Energy will continue to serve as a development partner through to the ready-to-build phase, marking the first collaboration between the company and Alight in Denmark.
This partnership brings together complementary strengths: Alight’s experience as an independent power producer with a growing Nordic portfolio, and GreenGo Energy’s local expertise in project development, permitting, and market navigation. Such collaboration is particularly valuable in early-stage projects, where local knowledge can significantly reduce execution risk.
By working together through the development phase, both companies can share responsibilities related to site optimization, regulatory approvals, and stakeholder engagement. This shared approach not only improves efficiency but also distributes risk, which is especially important in markets with evolving regulatory frameworks and permitting processes.
The Kalundborg project is a key component of Alight’s broader Nordic expansion strategy, which includes a growing pipeline of projects across Finland and Sweden. These markets share similar characteristics, including strong policy support for renewable energy, increasing corporate demand, and favorable conditions for solar deployment.
In Denmark, Alight has already established a presence through the acquisition of a 215 MWp solar park in Lolland, which has since been commissioned and ranks among the largest solar installations in the Nordic region. The addition of the Kalundborg project further strengthens its footprint, particularly by introducing hybrid capabilities into its portfolio.
This expansion reflects a strategic effort to build scale across the region, enabling operational synergies, improved asset management, and stronger positioning in negotiations with offtakers and suppliers. As competition intensifies, developers with diversified and geographically balanced portfolios are likely to have a competitive advantage.
Outlook: Hybrid Projects Driving Market Evolution
The acquisition of the Kalundborg project underscores the growing importance of hybrid renewable energy systems that integrate generation with storage. As electricity markets transition toward higher shares of intermittent renewable energy, the ability to provide flexibility is becoming a critical differentiator.
In the near term, the project’s progress will depend on successful completion of permitting processes, continued collaboration between development partners, and the securing of long-term offtake agreements. Each of these elements plays a crucial role in determining the project’s timeline, cost structure, and overall viability.
The inclusion of battery energy storage is expected to significantly enhance project economics by enabling energy arbitrage—storing electricity when prices are low and dispatching it when prices are higher. In addition, the system can participate in ancillary service markets, providing grid-balancing services that generate additional revenue streams.
From an operational standpoint, storage also improves reliability by smoothing out fluctuations in solar generation. This allows the project to deliver a more consistent and predictable power profile, which is increasingly valued by both grid operators and corporate customers.
Over the longer term, solar-plus-storage configurations are likely to become a standard feature of renewable energy development, particularly in regions with high renewable penetration and evolving grid requirements. These systems not only maximize energy utilization but also contribute to grid stability, supporting the broader energy transition.
For Alight, the Kalundborg project represents more than just an individual asset—it is a strategic step toward building a portfolio of flexible, high-performance renewable energy solutions.
