Wind and solar project agreements: what to do in the first ten days depends on which clause in the signed document starts the countdown, because Swedish law sets no default ten-day period of its own. The window usually comes from a notice provision, a condition precedent, or a termination right buried in the land lease, grid connection agreement, or EPC contract, and missing it turns a negotiable position into a fixed one.
Who this concerns
This concerns the developer or landowner who has just signed, received notice under, or is about to terminate a wind or solar project agreement, and the lender or grid operator tracking the same clause from the other side. It also concerns the EPC contractor who has just been issued a notice to proceed, because the ten-day window on the construction side rarely runs on the same clock as the land or connection side, even though both sit inside the same commercial deal.
The period rarely appears as a labelled deadline. It sits inside a definition of "Effective Date," a notice clause counted in business days rather than calendar days, or a right of first refusal that lapses if not exercised within a fixed window after signature or receipt. Reading the defined term correctly, rather than assuming what "ten days" means by default, is the first decision that matters.
When the counterparty, the ultimate parent, or the underlying asset sits outside Sweden, the ten-day clock still runs from the date fixed in the agreement, but who is authorised to receive the notice, in what form, and in which currency any related security is held depends on the law the parties chose to govern the document, not automatically on Swedish law. A joint venture structure with a foreign counterparty changes who inside the group can validly receive that notice on day one, and confirming the answer before day nine, rather than after, is what keeps the position intact.
The practical consequence of doing nothing is not neutral. If the window closes without the required notice, condition satisfaction, or filing, the agreement typically continues on its original terms, which is exactly the outcome the party invoking the ten-day period was trying to avoid. Inside the real estate and energy infrastructure practice, the recurring pattern is the same regardless of technology: the first genuinely irreversible step is usually the filing that establishes third-party priority, most often the land access notice lodged with the register, because that step fixes a position against later claimants independently of what the underlying contract goes on to say afterwards.
What the law says
Swedish contract law gives the parties wide freedom to set their own notice periods, conditions precedent, and termination rights, and a wind or solar project agreement typically uses that freedom rather than relying on a statutory default. There is no general rule that supplies a ten-day period where the contract is silent, and there is no general rule that extends or shortens a period the parties have already fixed.
Land rights, registration of easements, environmental permitting, and grid connection each sit in separate regimes, and none of them substitutes for what the agreement itself says about a ten-day period. A permit that is still pending does not stop a contractual notice clock from running, and a registered easement does not, by itself, satisfy a condition precedent that requires something else to have happened first. Under Swedish law as it currently stands, the starting point for any dispute about whether the window ran correctly is the wording of the clause and the date the relevant notice was actually received, not a general limitation period borrowed from another part of the agreement or from a different regime entirely.
How it works in practice
Day 1: identify which clause is actually running
Read the clause that triggers the period before doing anything else. A "ten day" reference to "signature," "receipt," or "the date of this notice" produces three different countdowns, and business days are not calendar days under most agreements used in this sector. Confirm this in writing internally before treating any date as fixed.
Day 1 to 2: confirm signatory authority on both sides
Check that the person who signed, or who is due to receive the notice, actually had authority to bind the counterparty on that date. A change in board composition, a pending assignment, or a parent company reorganisation between signature and notice can each put authority in doubt, and a notice served on the wrong entity does not stop the clock from running against the sender.
Day 2 to 4: assemble the land rights file
Pull together the title, the lease or easement instrument, and anything already lodged with the register; the underlying land access and easement documents are usually the fastest way to see what is actually missing. Gaps in this file are the most common reason a ten-day position collapses later, because the notice or filing turns out to rest on a right that was never properly perfected.
Day 3 to 5: check the conditions precedent, not just the deadline
A ten-day window is frequently tied to satisfaction of a condition precedent rather than a bare calendar date. Confirm which conditions have actually been met, in what order, and whether the warranty and indemnity terms agreed at signature are still accurate at the point the clock starts, because a stale warranty can reopen a clause the other side thought was closed.
Day 4 to 6: read the grid connection agreement's own clock
The grid connection agreement usually runs a separate notice regime from the land or EPC side, and its own deadlines do not pause because a different ten-day period is running elsewhere in the same project. Check whether the connection agreement requires its own confirmation, deposit, or milestone notice inside the same window, because the two clocks are easy to conflate and rarely coincide by accident.
Day 5 to 7: notify the parties who need to know, in the right order
Lenders holding security over the same asset, co-developers, and the grid operator each have their own notice requirements running in parallel. Notifying them out of order, or notifying the wrong entity within a group, does not stop the ten-day clock, it just adds a second problem on top of the first.
Day 6 to 8: check insurance and security instruments
Confirm whether any guarantee, bond, or insurance cover referenced in the agreement is tied to the same trigger date, and whether it needs to be renewed, drawn, or notified within the same window. A security instrument that lapses quietly during the same ten days can undo the value of correctly exercising the underlying clause.
Day 7 to 9: preserve the record
Keep the transmission and receipt evidence for every notice sent or received in this window: method, timestamp, and recipient. If the position is challenged later, this record, not a recollection of what was intended, decides whether the clause was validly exercised.
Day 9 to 10: decide what happens if the window closes unused
If day ten arrives without action, know in advance whether the agreement continues unchanged, whether a right lapses permanently, or whether a longer cure period opens up. That answer should be established before day ten, not worked out afterwards, because the choice of whether to act on day nine or day ten often turns on what the fallback actually is.
What to check
- The exact wording of the clause: business days or calendar days, from signature or from receipt.
- Signatory authority on both sides, current as of the notice date, not the signature date.
- Whether the underlying land right is registered, and if not, what step perfects it.
- Whether any condition precedent tied to the same period has actually been satisfied.
- Method and proof of delivery for every notice sent inside the window.
- Whether a parallel notice obligation to a lender or grid operator exists and has been met.
- Whether any security or insurance instrument referenced in the agreement shares the same trigger date.
What must an energy contract's warranty and indemnity clause say to hold up later?
An enforceable warranty and indemnity clause states clearly what is warranted, on what date, for how long, and what remedy follows a breach, rather than relying on general representations. In a wind or solar agreement, the warranty date matters as much as its content, because a warranty given at signature does not automatically survive to the date a later notice period runs against it.
When does a Swedish joint venture partner count as facing a foreign counterparty?
A Swedish joint venture partner faces a foreign counterparty whenever the other shareholder, its ultimate parent, or the entity actually signing project documents sits outside Sweden, even if a Swedish subsidiary is the named party on paper. That distinction changes which law governs notices, security, and dispute resolution inside the joint venture agreement itself, separately from the project agreement it was set up to hold.
Which regime applies if a party applies for interim measures during the ten-day window?
Whether a Swedish court, an arbitral tribunal, or a foreign court can freeze assets or grant interim relief during this period depends on where the agreement sits jurisdictionally and what forum clause it contains, not on the ten-day period itself. A party expecting to invoke the window should confirm this in advance, because an interim measures application filed by the other side can freeze the practical value of exercising the clause even if the clock has not run out.
The numbers
No statutory deadline applies by default: the ten-day period in a wind or solar project agreement is contractual, and its exact length, and what interrupts it, come from the clause itself rather than from a fixed rule of Swedish law. Nothing in this note substitutes a figure the agreement does not already contain.
What does vary in ways that affect cost is the number of parcels or easements chained together under the same agreement, whether the counterparty side consists of a single lessor or a group of individual landowners who must each be notified separately, and whether a dispute over one of the underlying instruments already exists before the window opens. Each of those factors multiplies the number of documents that must be checked inside the same ten days, which is what drives the cost of getting this right, not the length of the period itself. A single-parcel agreement with one counterparty and no pending dispute is a different exercise from a multi-parcel corridor with several landowners and an open disagreement over one easement, even though both run on the same ten-day clause.
Where it usually goes wrong
The most common failure is treating "ten days" as a calendar fact rather than a defined term, and only discovering during a dispute that the agreement counts business days, or counts from receipt rather than despatch, which shifts the actual deadline by several days in either direction.
A second failure is assuming that Swedish law fills gaps the agreement leaves open. It generally does not: if the clause is silent on what happens when the tenth day falls on a public holiday, or on how notice must be served on a counterparty registered abroad, that silence is resolved by interpreting the agreement, not by a default statutory rule.
A third failure is treating the land, EPC, and grid connection clocks as one clock. They rarely share a trigger date, and satisfying one does not satisfy the others, even where all three appear in the same set of contracts negotiated at the same time.
A fourth failure surfaces once a dispute has already started elsewhere. If the counterparty applies for interim measures or an asset freeze in a different forum while the ten-day window is running, exercising the clause on day ten may become academic if the underlying asset is already restrained, regardless of whether the notice itself was valid.
None of this applies where the parties have since varied the agreement in writing, or where a later instrument expressly supersedes the clause that created the ten-day period; the analysis then starts from the amendment, not from the original text.
What to do next
Self-directed work covers reading the clause correctly, assembling the file, and preserving the record inside the ten days. It stops at the point where the clause has to be read against the actual land title chain, the grid connection terms, and any parallel lender consent, because that reading decides whether the position taken on day ten will hold. Where a related planning decision is also in play, the planning decisions and appeals guide sets out the first ten days on that separate track. Where the file needs to be checked against the underlying documents before day ten runs out, that is an assessment, not a further checklist, and it starts with booking an assessment call.
