Benefits of Microgrid Solutions to Data Centre Stakeholders

The microgrid is undergoing a renaissance that is changing the global power landscape through the integration of clean power generation, renewable power sources, large scale battery energy storage and advanced control systems.  

For data centre campuses, single building hyperscale facilities, and emerging Edge formats, AVK microgrids have rapidly evolved to provide a range of sustainable energy infrastructure solutions. 

This is not a theoretical proposition. It is a proven, working, practical reality. March 2026 saw the culmination of over 7 years work between AVK and Pure Data Centres Group – together we announced Europe’s first data centre microgrid, operating independently from EirGrid. The first of its kind deployment at Pure DC’s hyperscale AI campus in Dublin, Ireland, is designed to provide 110MW of capacity without relying on the country’s grid power.  

The successful delivery of the highly complex DUB01 Pure DC project is proof of how microgrids can surpass a traditional grid connection in terms of reliability and power security along with multiple immediate benefits for the operator, customers and the locality, plus long term benefits for investors and developers.

The explosion of stakeholder interest in microgrids 

What lies behind the explosion of stakeholder interest in microgrid power solutions across the data centre industry?

The answers are simple and complex. A simple answer is that GW levels of power demand for AI infrastructure is outstripping available grid capacity.  This is particularly true in large metropolitan areas where traditional demand for data centre capacity was at its greatest. This is a global issue but is especially pronounced in Europe’s tier 1 and tier 2 city markets. Secondly, as has been well documented, traditional energy providers are struggling to keep pace with grid reinforcement to serve the electrification of whole industry sectors, businesses, transport and consumer demand as each competes for power access and availability. 

It is in this context that microgrids provide multiple benefits to aid success at every stage of data centre development. These range across incentives, planning, permitting, zoning, financial imperatives, regulatory and compliance, operational objectives, sustainability, district heating, delivering power security for critical IT workloads while extending to generating economic dividends for localities. 

The benefits of microgrids apply to all data centre categories and stakeholders from initial investors, across the construction process, through the operating value chain all the way into the communities where data centres will operate for decades. 

Stakeholder benefits: investors, developers, operators, communities

Microgrids for investors and financial asset managers

Investors dislike uncertainty. Both the funding community and development ‘paper issuers’ seeking institutional debt, private credit or equity capital investment recognise access to power as the new bottleneck for successful project development. 

Addressing a recent UK data centre conference, one investor said: “Where it comes to grid connections the project cannot begin until there is a cable to the site. The issue is the timing of grid connections, even when agreed, can change.”  

Asset managers are reporting multiple AI projects on their books seeking GW scale power. This is changing the risk profile of investments, with power now the key consideration. Among the investment community there is a recognition of how microgrid power accelerates development timelines – shortening time to Ready for Service (RFS) and therefore time to value for investors.

For those seeking new opportunities in Europe there is growing acceptance of the time, cost and revenue benefits of on-site power provision. 

Microgrids for developers

Microgrids address both short term issues of time to market in response to demand and longer term industry access to power concerns where changes to grid connection criteria changes and grid infrastructure reinforcement can take decades. There are already reports of viable, large scale cloud data centre projects which may not proceed due to power access problems.  

Uncertainty around grid connection also restricts location choices on greenfield, brownfield and repurposed sites and are impacting the opening up of new sites. There is growing evidence that data centre developers are being asked by grid operators to move away from the areas of highest AI and cloud customer demand to locations where there is available power.  

On the capacity side, average data centre sizes are scaling to 100s of MWs and beyond. Microgrids enable developers to ramp on-site power generation. This breaks large developments into modular energy zones for phased expansion of campuses without relying on grid upgrades. Microgrids also allow for testing of on-site generation and storage at smaller scales. This ramping approach can help large scale developments satisfy zoning authorities while progressively proving viability. 

In the longer term, microgrids providing prime baseload do not mean data centres must remain unconnected from the grid for their operational lifetime. In fact, microgrids open new options for future grid connectivity delivering significant advantages both for the data centre and the grid. 

Planning and permitting  

It is already widely recognised that developments that avoid reliance on local utility grid upgrades can remove lengthy planning delays. Developers are aware that a major bottleneck to developing  and constructing data centres is the navigation of planning regime processes which are locally controlled.  

A major advantage of microgrid systems is the combination of generation, storage, and demand management under one infrastructure which can help reduce the number of separate permits required (generation, grid connection, storage) through Enhanced Master Planning Flexibility.  

Grid support and ancillary services 

Data centre microgrids can supply services back to the grid, such as frequency regulation, voltage support, and demand response. Demand response services can also provide microgrid operated data centres with additional revenue streams and permitting advantages. 

Operator cost and revenue opportunity benefits  

Microgrids can lower operational costs, as grid connected microgrids can provide peak shaving and load shifting options, which can reduce peak demand charges. There is also decreasing predictability in grid access tariffs, capacity charges, and congestion pricing across European markets with costs rising. There may be reduced grid charges and more pricing predictability via the microgrid route. 

AVK microgrids are the foundation of continuous operation at predictable and managed cost. However, AVK thinks about cost not just as an economic consideration but also in environmental impact terms.  

Sustainability and regulatory benefits 

As European policies increasingly mandate energy efficiency, renewable integration, and storage readiness, microgrids are helping future-proof sites against regulation. Europe is advancing its stringent climate targets (Fit for 55, REPowerEU) and data centre microgrids can accelerate compliance through connections to solar and wind renewables integrated with onsite BESS. 

Across Europe, energy codes are changing. Microgrids position data centres ahead of forthcoming energy codes and net-zero roadmaps, reducing risks of future corrective actions or added compliance costs. They also enable corporate reporting on Scope 2 and 3 emissions. 

Through compliance with EU policy, microgrids are turning data centres into good citizens and neighbours through lower carbon emissions and adhering with future regulatory framework requirements. Microgrids don’t resolve all the energy sustainability complexities of data centre developments, but they are an increasingly important element in areas such as EU regulatory frameworks where streamlined approvals for renewable and storage assets are evolving. 

A major study and a resulting energy transition research paper (a collaboration between AVK and our technology partner Wärtsilä) covered renewables, internal combustion generation, and energy storage across different balanced approaches. It details the comparative benefits of different microgrid development modelling options.

The study measured the impact of four different power configurations for an 80MW data centre located in Northern Europe using combinations of renewables, engines and storage and their impact on emissions.  It was found that mixing combined gas cycle turbines with renewables and battery storage looks like the most promising model. 

Community benefits 

The benefits of microgrid powered data centres extend to local communities. Microgrid based data centres are particularly beneficial for the development of urban brownfield sites where grid power is constrained. European cities and regions are increasingly adopting Local Energy Communities (LECs) and district energy strategies.  

Microgrids mean data centres can: 

• Participate in demand response and balancing markets. 
• Support municipal climate and resilience planning.
• Integrate with local energy networks (e.g. provide waste heat to communities).  

By placing microgrid power sources close to communities this can improve power security through local grid interaction but also enable the development of local district heating schemes for public, municipal and residential use. Policies are emerging for creating local, long term skilled jobs associated with large data centre developments (beyond the construction and operational roles) to build digital micro-economies outside the data centre perimeter. 

Microgrid powered data centres can act as a catalyst to the formation and building of local tech business ecosystems in AI, software and digital services. As well as economic benefits, community engagement extends to acknowledgement and understanding of local environmental and sustainability concerns – which for developers can be encapsulated within “social license to operate”. 

For AVK, sustainability is not a bolt-on but a fully integrated, responsibility-driven strategy aligned with the United Nations Sustainable Development ensuring positive impact ‘For People and Planet’.
