Integrated renewable energy systems

Solar, wind, batteries and controls should work towards one objective. We plan around your site’s needs and coordinate delivery with suitable project partners.

Earning through frequency reserves

Reliable power. A chance to earn extra income.

With a suitable battery and controls, your solar system may earn extra income. Frequency reserve markets pay systems to help keep the electricity grid balanced. We check your equipment and grid connection to see whether this could work for you.

With our aggregator

We have an aggregator — a service provider that controls the battery and manages market participation. We help connect your system.

With your chosen aggregator

Already have an aggregator, or prefer another one? We can build a compatible system. We check equipment and control requirements before you order.

Before starting, we check suitability, carry out required tests and agree the terms. Income changes with the market. We also agree how much battery energy to keep for backup.

Plan around the needs of your site

For a business, building or remote site, we review consumption, generation opportunities and the required continuity of supply. When expanding an existing system, we first identify equipment to retain and integration requirements.

The combination of solar, wind and battery storage follows from the location and project brief. You can commission a single stage or the planning and delivery coordination of a complete system.

Grid-connected, hybrid or off-grid

For a grid-connected site, we consider the existing connection and intended demand management. For islands and remote locations, we can develop the brief for an independent power supply or hybrid system.

Alongside generation and storage, we assess the need for backup power. The solution may include a generator and fuel supply, or a fossil-free option where conditions permit. Suitability is assessed using the specific site’s data.

One coordinated project

The agreed scope can bring together engineering, equipment selection, electrical work, controls and partner activities. The proposal defines stages and responsibilities so you can see exactly what is included.

We also agree testing, documentation and operator instruction. Where needed, we discuss monitoring and maintenance arrangements after commissioning.

What is included in the price?

The quote lists the equipment and work included. We agree installation, setup, testing and user guidance, along with warranty, maintenance and any aggregator connection.

Your questions

Questions and answers

What should you know before ordering?

Can a site be powered without a grid connection?

Yes. An independent supply can be designed around consumption and use. It may combine solar, battery storage and, where needed, a generator or wind power in suitable conditions.

Is the solution suitable for year-round use?

Year-round use must be part of the design brief. We consider consumption, seasonal generation, backup energy and maintenance access. A system designed for summer use needs a separate assessment for winter operation.

Can I order just design work or one stage of the project?

Yes. The scope can cover a site assessment, design, equipment selection and supply, or coordination of a specific stage. Coordination of the complete project can also be agreed.

Who brings the equipment and disciplines together?

FutureEnergy’s role can include developing the complete solution, delivering the project and coordinating specialist partners. We agree responsibilities, tasks and handover conditions before work begins.

How long does project delivery take?

Timing depends on design scope, required approvals, equipment lead times, construction work and site access. Once the brief is defined, we can prepare a realistic schedule and identify its key assumptions.

What happens after installation?

Before ordering, we clarify commissioning, testing, documentation, user guidance and equipment and installation warranty terms. Monitoring, maintenance and periodic inspections can be agreed separately.

How can an existing solar park create more value?

We review generation, consumption and the grid connection. Suitable storage and controls may increase self-consumption, help time electricity purchases and sales, and enable frequency reserve market participation. We assess these uses together: the same battery capability cannot be committed without limit to every task at once.

Can I order a complete market-ready solution?

Yes. The scope may cover assessment, design, equipment selection, electrical work, automation, aggregator integration and coordination of required tests. Participation depends on meeting technical requirements and having the necessary agreements.

Can an off-grid system participate in frequency reserve markets?

A fully off-grid system cannot participate in the public electricity grid’s frequency reserve markets. For these sites, we focus on independent supply, reliability and managing energy costs.

More value from your energy system.

Describe your site and goals. We help combine generation, storage, backup and market participation where suitable.

Advertising measurement choices

With your permission, we send OpenAI an event only after an enquiry is successfully sent, with an advertising click reference when available. We do not send your name, email address or message for measurement. You can use the form if you decline and change your choice in the footer.

Your information.

Controller

FutureEnergy is a brand of Baltic Energy Engineering Service OÜ. For privacy enquiries, email almer@futureenergy.ee or call +372 5686 8083.

Enquiry form

The form sends your name, email address, selected service, location and message to our server, which uses Resend to send an email to almer@futureenergy.ee. The recipient mailbox is hosted by Zone. We use these details to answer your enquiry and prepare a proposal at your request. The legal basis is taking steps at your request before a contract, or our legitimate interest in responding to a business contact.

A success message means the email service has accepted the message for delivery; it does not confirm that it has been read in the mailbox. Your text stays in the form after an error. Unsent form content is not saved in persistent browser storage.

Security and retention

The website is hosted by OpenAI Sites on Cloudflare infrastructure. Security tokens, a hidden control field and rate limits help prevent spam and duplicate messages. The website database holds a random request reference, a keyed content digest, sending status and timestamps. It does not store your name, email address or message. Rate limits use keyed hashes of IP addresses and email addresses, not their original values. Hosting and email providers may process technical logs needed to operate their services.

Technical sending records older than seven days and expired rate-limit records are removed when the form is next used. A technical retry reference stays in your browser for up to seven days or until the session ends. We retain mailbox correspondence as needed to resolve the enquiry and manage any resulting contract, and for applicable legal obligations or the limitation period for claims.

Advertising measurement

Measurement is off without your consent. When measurement is active and you separately allow it, our server sends OpenAI’s Conversions API only a successful enquiry event (lead_created), random request reference, time, page address and advertising click reference (oppref), when available. We do not send your name, email address, message or hashes of those details for advertising measurement. Reusing the request reference prevents duplicate counting. Clicking the send button or opening an email link is not measured as a sent enquiry.

We do not load an advertising pixel or use advertising cookies. Your measurement choice is stored in local browser storage for up to 180 days; the advertising click reference is stored only with consent, for up to 30 days. You can withdraw consent at any time through “Advertising measurement choices” in the footer. This stops future measurement and deletes the locally stored click reference. Withdrawal does not affect processing that took place beforehand. You can use the form if you decline.

Providers and your rights

OpenAI, Cloudflare and Resend may process data outside the European Economic Area. Information about their data protection and safeguards for cross-border processing is available in the privacy policies of OpenAI, Cloudflare and Resend.

Where applicable, you can request access, correction, deletion, restriction or portability of your personal data, and object to processing based on legitimate interests. Contact us to exercise these rights. You can also complain to the Estonian Data Protection Inspectorate.
