BESS · PV co-location · energy infrastructure

Independent BESS site assessment.

Before you invest in a BESS site, ENFAN assesses land and project ideas for battery storage, PV co-location and energy infrastructure independently – with no proprietary land interest, no EPC commission and no trading mandate. The result is a robust decision basis for grid access, permitting, stakeholder acceptance and site option value.

Grid access Permitting Stakeholder acceptance Commercial viability

Why ENFAN

The right plot is only the beginning.

A battery storage project is not viable simply because land is available or inexpensive. What matters is whether bidirectional grid access, permitting path, technical configuration, local stakeholder acceptance and commercial rationale fit together. ENFAN assesses these factors at an early stage and with an open outcome: if a site does not appear viable, this is stated clearly before major costs for studies, grid applications, leases or project acquisitions arise.

Site logic

The best BESS site is not the cheapest site.

It is the site with the highest option value: technically connectable, permitting-feasible, communicable to local authorities and open to multiple revenue models over time. Since many storage ideas compete for scarce grid and permitting capacity, early site logic separates realistic projects from costly detours.

Target groups

Who ENFAN works for.

ENFAN supports early decisions wherever land, grid access, permitting and commercial rationale need to be brought together.

Landowners

Initial assessment of whether a plot may be relevant for battery storage, PV, co-location or energy infrastructure.

Municipalities

Assessment of how storage projects can be integrated into municipal decision processes in terms of planning, communication and local benefit.

Investors

Independent prioritisation of project ideas and pipelines regarding grid-access probability, permitting risk and implementation maturity.

Project developers

Early-phase site check before significant costs arise for studies, grid-connection procedures or project acquisitions.

Municipal utilities

Structuring local flexibility, storage and co-location projects at the interface of grid, generation, load and municipality.

PV and wind-park operators

Assessment of whether storage at existing or planned generation sites can create value through co-location, curtailment reduction or market capability.

Check land

Which plots can be relevant for BESS and co-location?

A plot only becomes viable when grid access, planning law, technical access, distances, site access and stakeholder acceptance fit together. Indicative size requirements depend strongly on the project: medium-voltage systems require significantly less land than large-scale storage near high-voltage infrastructure; the decisive factor remains the specific grid-access and permitting feasibility.

Proximity to substationsLand near suitable medium- or high-voltage infrastructure can be an important starting point.

Commercial and industrial sitesLoad proximity, access and existing infrastructure can support storage projects.

PV and wind sitesCo-location can combine generation, storage and market options in one site concept.

Brownfield and conversion sitesBrownfield and conversion sites can be interesting from a land-use planning perspective but require technical, land-use and permitting review.

Charging hubs and logisticsStorage can buffer charging power, reduce peak loads and structure grid expansion more economically.

Municipal infrastructureDepots, waterworks, wastewater plants or utility sites can become local flexibility anchors.

ENFAN Site File

A site idea becomes a reviewable decision document.

The ENFAN Site File bundles the relevant review fields for an initial go/no-go decision and creates a solid basis for further discussions with the grid operator, municipality, owner, investor or project partner. It is designed as a compact decision document; scope and depth depend on data availability, site complexity and mandate.

Co-location potential

Evaluate PV, wind, storage, load and grid access together.

ENFAN assesses whether a storage site should be considered as a stand-alone project or whether a combination with generation, load, charging infrastructure or municipal infrastructure creates a more robust project profile.

PV-BESS

Connect generation and storage

Co-location can help make local generation more usable and build site value across several revenue and use-case logics.

Load proximity

Commercial sites, charging hubs and infrastructure

Where demand and grid constraints meet, storage can be more than a trading asset.

Strategy

Prepare for partners

A solid pre-check makes a project easier to connect to later EPC, trading, financing and operator partners.

FAQ

Frequently asked questions on BESS sites.

Is proximity to a substation always sufficient?

No. Distance alone is not decisive; the concrete bidirectional connection option, grid capacity, voltage level, protection concept and connection economics matter.

What land size is required?

This depends strongly on power, storage duration, technology, required distances, access roads, transformers and expansion options. ENFAN therefore works with indicative ranges and assesses the specific site logic.

When should the municipality be involved?

Early. Stakeholder acceptance, local-benefit arguments and a realistic permitting path should not be considered only after detailed technical planning.

Is a PV connection automatically a storage connection?

Not necessarily. Feed-in and consumption must be assessed separately. For battery storage, the import and export capability of the connection is a central point.

Why ENFAN and not a large engineering firm?

Large engineering firms are strong in detailed planning, specialist studies and permitting documentation. ENFAN starts earlier: in the phase where the question is whether a site justifies that next planning stage at all.

What does a site check cost?

Costs depend on data availability, review depth and site complexity. For clearly defined initial checks, ENFAN can prepare a fixed-price offer.

What does ENFAN deliver in the first step?

A structured initial assessment with review fields, open questions, project risks, prioritisation and a proposal for the next robust work step.

Is ENFAN a trader or EPC?

ENFAN positions itself as an independent early-phase, site and structuring partner. Trading, construction or operator partners can be involved later on a project-specific basis.

Does ENFAN provide specialist planning?

No. ENFAN does not provide fire-protection or safety specialist planning and does not replace required specialist studies. ENFAN identifies the relevant interfaces, review questions and next specialist steps at an early stage.

Profile

Planning competence for the next generation of energy projects.

Dr. Eva Frensemeier combines spatial planning, permitting strategy and renewable-energy project development. Her focus is the early question of which sites are truly viable for battery storage, PV co-location and decentralised energy infrastructure.

ENFAN applies this experience to a central bottleneck in the energy transition: bringing together land, grid access, municipal acceptance and economic benefit so that a site idea can become a realisable project.

For larger mandates, Dr. Eva Frensemeier works with a project-specific curated expert network. This keeps ENFAN personally led while enabling several site, permitting and due-diligence projects to be supported in parallel with solid expertise and without unnecessary overhead structures.

Planning & permitting PV & battery storage Municipal integration w.one network

Curated expert network

Personal leadership, precisely matched expertise.

ENFAN is deliberately designed as a lean, high-quality advisory structure. Dr. Eva Frensemeier remains the central contact and technical project lead. For specialist questions, a curated expert network is involved per mandate – exactly as large as the project requires.

This model combines personal responsibility with access to additional expertise in grid, technical interfaces, permitting strategy, market model, financing, communication and stakeholder acceptance.

Insights

Expert topics for early site decisions.

BESS

Why bidirectional grid access is the first hard test

A generation feed-in connection is not yet a robust storage connection. Import and export must be assessed as an independent site question.

Co-location

Think PV, storage and load together

Storage creates the greatest value when it connects local generation, consumption and market options.

Stakeholder acceptance

Communication is not an add-on module

Transparent involvement and local value creation often determine speed and feasibility.
