Power Supply Agreements: Enforceability, Pricing, and Termination Rights

A power supply agreement must contain specific operative provisions to create binding obligations and withstand challenge. The contract should detail the supplier's duty to deliver power at specified voltage and frequency, your obligation to accept and pay for that supply, and the term over which those duties run. Courts examine whether the parties clearly manifested intent to be bound, whether material terms were agreed, and whether consideration flowed both ways.

Enforceability also depends on compliance with state utility law and, where applicable, federal Energy Regulatory Commission (FERC) standards. If your business qualifies as a large industrial consumer in a deregulated market, the contract may be subject to different regulatory scrutiny than a standard commercial utility service agreement. Ambiguities in capacity guarantees, pricing formulas, or termination rights often become dispositive in dispute, which is why precise drafting and contemporaneous documentation of performance are essential to your defense posture.

A supply agreement also functions as a risk allocation tool. By identifying which party bears the cost of transmission losses, equipment failure, or regulatory change, you can assess your true exposure and plan accordingly. Courts typically enforce these risk-allocation clauses as written, provided they are not unconscionable or contrary to public policy.

Your supplier's core duty is to deliver power in the quantity and quality specified. Breach occurs when delivery falls below contractual minimums without valid excuse. Common defenses to a breach claim include force majeure (unforeseeable events beyond the supplier's control), your own material breach or failure to accept delivery, or regulatory action that makes performance impossible.

As the consumer, you must also establish that you complied with your payment and acceptance obligations. If you rejected delivered power without contractual justification or failed to pay invoices when due, the supplier may have a defense to your damages claim. Courts often require the party alleging breach to prove that performance was due and owing, that the other party failed to perform, and that the failure caused measurable harm.

Documentation of performance is critical. Maintain records of power flows, quality measurements, invoices, payment dates, and any written notices of non-conformity. In the event of a dispute, these records establish the factual foundation for your claim or defense. A procedural misstep, such as failing to give timely written notice of a defect as required by the contract, can bar your remedy even if the underlying breach is clear.

Power supply agreements often include price adjustment mechanisms tied to market indices, fuel costs, or regulatory changes. These clauses can create disputes if the index is discontinued, if the formula is ambiguous, or if one party claims the adjustment was unconscionable. Your contract should specify how disputes over index selection or calculation are resolved, whether through negotiation, expert determination, or arbitration.

When pricing disputes arise, courts examine the plain language of the adjustment clause and the intent of the parties at formation. If the clause is silent on a contingency that later occurs, such as the discontinuation of a referenced index, courts may imply a duty to select a reasonable substitute index or may declare the clause unenforceable. You should review your contract's adjustment provisions with counsel before a dispute occurs, to understand your exposure and any defenses available if the supplier attempts to impose unexpected rate increases.

A related issue is the interaction between your power supply agreement and any power purchase agreement you may have with a third party. If you resell power or use it as a component in a larger supply chain, misalignment between your purchase and sale terms can create mismatch liability. Ensure that force majeure clauses, adjustment mechanisms, and termination rights are compatible across all agreements.

Termination provisions define when either party can exit the relationship and what happens to your supply if termination occurs. Some contracts allow termination for convenience with notice; others restrict termination to material breach or specified events. The contract should also address what happens to your power supply during any wind-down period and whether you have the right to source replacement power at the supplier's cost if early termination is the supplier's fault.

Remedies for breach typically include damages for the cost of substitute power, business interruption losses, and in some cases, specific performance (a court order requiring the supplier to deliver). However, courts enforce liquidated damages clauses and damage caps as written, so your contract may limit recovery even if actual losses are higher. You must also mitigate damages by taking reasonable steps to source replacement power; failure to mitigate can reduce or eliminate your damages award.

Your power supply agreement should include a dispute resolution mechanism, such as negotiation, mediation, or arbitration. Arbitration clauses are generally enforceable and can limit your access to courts, so review them carefully before signing. Some agreements provide for expert determination of technical disputes, such as whether power quality met contract specifications, which can be faster and cheaper than litigation.

Force majeure and impossibility clauses are critical to your risk profile. These clauses excuse performance if an unforeseeable event beyond the parties' control makes performance impossible or illegal. However, courts interpret force majeure narrowly and require that the event be truly unforeseeable, not merely difficult or expensive. Market price increases do not trigger force majeure, nor do regulatory changes that were reasonably foreseeable. You should understand what events your contract covers and what events are excluded, so you can plan for contingencies and assess your true operational risk.

Before executing a power supply agreement, conduct a thorough review of your operational needs, your supplier's financial stability, and the contract's termination and remedy provisions. Ensure that the agreement aligns with your business model and that you have a clear exit strategy if circumstances change. Document all communications with your supplier in writing. Oral modifications to the contract are often unenforceable or disputed, so confirm any changes in email or a signed amendment. Maintain records of power deliveries, quality measurements, invoices, and payments. If a dispute arises, these contemporaneous records are your strongest evidence of performance or breach and can support your position in negotiation, mediation, or litigation.
