The June Anchor
Why any expiration date on an electricity supply contract other than June is costing you more than realize.
Why the wholesale pricing matrix rewards a June anchor.
Every commercial electricity renewal that Alden runs targets a June expiration. Late May through the first week or two of July all count as the flex band; June is the middle. The pattern held on the wholesale pricing matrix through fifteen years of contracts and it holds today. This page explains why. If a contract expires in another month without a specific reason, something in the last renewal was suboptimal, and the pattern is worth understanding before the next one.
Twelve expiration months, one lock target, one overlap.
The disciplined lock target for any fixed-price contract is seven to nine months before expiration. That range provides enough runway to catch a favorable market and enough proximity to price with confidence. The gold band on every row below marks that fixed T-7 to T-9 target. What shifts row-to-row is the position of the two annual soft windows in gas seasonality (green), because they occur in fixed calendar months while the expiration date moves. The overlap between gold and green is where the buyer gets to lock during a soft window with disciplined runway. Read down the twelve rows and count the overlaps.
The clean visual reading is that May, June, and July are the only three rows where a green soft window sits squarely on top of the gold T-7 to T-9 target. May sits deepest inside the target. June and July have their fall window partly inside and partly outside. April's fall window straddles the target edge and the casino zone, giving it a small penalty. For March, February, January, and December, the fall soft window is buried inside the red casino zone, meaning the natural fall shopping window arrives too close to expiration to be useful. September and October are the interesting middle case: their spring window (Feb through Mar of the same year as expiration) does overlap the target band, so the lock geometry is workable. What those months give up is not lock timing but strip composition, because a contract starting in fall puts winter volatility at the front of the strip where near-term hedging premiums live. Same problem in a different shape.
The pattern is elementary. It shows up plainly in the wholesale pricing matrix and anyone who prices contracts directly for a few years picks it up. What makes it news to most commercial buyers is a structural quirk of how the brokerage side of the market operates. Most brokers do not price their own deals. Their inquiries go to a pricing desk that returns numbers on request, and the desk sees isolated quotes rather than patterns across contracts. If the broker does not know to ask about expiration timing, the desk does not volunteer it, and the buyer never hears it.
Alden prices its own deals. Fifteen years of watching the matrix directly is where this pattern comes from. A broker who does not raise the June anchor with a customer has likely never seen the shape of the matrix themselves. The specific reason matters less than the result, which is that the buyer signs into a suboptimal shape without knowing to ask.
Three overlapping forces, all pointing at June.
The grid above is one way to see the alignment. The reasons behind it are three separate mechanisms that all reinforce one another.
The lock target aligns with the fall soft window.
The disciplined lock target is 7 to 9 months before expiration. For a June expiration, that range sits between late September and late November, which is exactly when gas seasonality softens the forward curve. For every other expiration month, the T-7 to T-9 range and the soft window fall apart, forcing the buyer to compromise on runway or on price.
Thanksgiving is a memorable pencils-down anchor.
A June expiration has Thanksgiving at T-7. A hard, memorable calendar deadline anyone in a business can hold in their head is worth more than any abstract T-minus schedule. For non-June expirations, there is no equivalent anchor date, and most buyers drift toward the casino zone by default because there is nothing on the calendar telling them to move sooner.
Wholesale hedge books concentrate on June shapes.
Retail providers assemble fixed-price offerings by hedging positions in the wholesale market. Because most commercial contracts in ERCOT have settled on the June anchor for decades, wholesale traders see concentration of that shape in their books. A June contract slots into an existing hedge bucket. A non-standard shape has to be individually hedged, which adds friction cost that gets passed into the quote.
What each expiration month gives up.
Grouped by how far the expiration sits from the June anchor.
Wholesale book concentration is strongest. Thanksgiving anchor applies with slight variation across the band. Late May contracts sit slightly tighter (fall window ends closer to expiration); early July contracts sit slightly looser. Anywhere in the last week or two of May through the first week or two of July counts as flex. June is the middle.
April expirations sit close enough to the June anchor that a portion of the fall soft window still lands in the T-7 to T-9 target range. The other portion of that window spills into the casino zone. A disciplined buyer can catch the useful portion in early to mid October. The pricing matrix prints tighter than for the winter-core months but consistently looser than for the flex band.
The spring soft window of the same year sits inside the T-7 to T-9 target zone for these months, so a disciplined buyer can catch a lock in late February or early March. What these months give up is not lock timing but strip cost, because a fall-start contract puts the immediately-following winter at the front of the strip where near-term hedging premiums are highest. The pricing matrix picks this up as a small but consistent penalty against the June baseline. The Sept-Oct band is more common in practice than most buyers realize and is rarely the worst option, but it is not the best one.
For an August expiration, the fall soft window ends before the lock target opens. For a November expiration, the spring window arrives after the target has passed. Both months force the buyer to either lock 12 or more months out during a distant soft window, or accept a lock in a non-soft window. Wholesale book concentration is thinner. Consistent penalty against the June baseline of two to three percent in a normal market.
The next contract begins right as weather risk peaks, which puts winter volatility at heavy near-strip weight. Neither soft window falls inside the T-7 to T-9 target zone, so there is no clean disciplined lock target in the natural range. The only workable option is locking through a soft window 11 to 14 months out, which requires long-runway discipline most commercial buyers do not carry. March sits at the tail of this group and prints marginally better than the winter-core months but still carries the strip-composition penalty.
How large is the penalty?
Not enormous per contract. In a normal market, the pricing matrix penalty for a non-June expiration typically runs 2 to 5 percent on the fixed rate, with the worst months at the higher end of that range against a June baseline. Small compared to the overall cost of electricity. Real when it compounds.
A 3 percent penalty is about six thousand dollars a year.
Applied to a mid-market commercial account, the math is straightforward. A single non-June contract is not going to sink a business. Over multiple renewal cycles, the compounding matters.
June-anchored fixed rate · $70 / MWh
Non-June penalty · 3% · adds $2.10 / MWh
Annual cost impact · $6,300
36-month term impact · $18,900
The larger cost is not the per-contract premium. It is that a buyer on a non-June cycle is systematically shopping every future renewal against the wrong market conditions. Peak-summer decisions get made against peak-summer forwards. Winter-decision cycles get made against winter-decision curves. Over three or four renewals, that pattern reliably lands the buyer near the top of the market rather than the bottom. The compounding is where the money lives.
One legitimate reason to sit outside the June anchor.
Lease alignment.
If your business occupies leased space and the lease terminates on a fixed date, aligning the electricity contract expiration to the lease terminus avoids buying orphan contract months against a vacated meter. Better to expire in October matching a lease end than to lock a June contract that runs past the move-out date and leaves you paying for supply on a meter you no longer occupy. This is the only reason to deliberately choose a non-June cycle, and even then the recommendation is to shape the contract as tightly as possible around the lease dates rather than defaulting to a full 36-month term that runs past the exit.
If your contract expires in another month.
Most contracts can be migrated to June at no additional cost.
The migration happens at the next renewal cycle rather than requiring an immediate move. The important step is naming the goal explicitly and structuring the next term toward it. Three common paths:
- Rotate through term length. Sign a term slightly shorter or slightly longer than the standard 36 months to shift the expiration month toward June. A 30-month term or a 42-month term produces a June expiration from most starting points.
- Layer a bridge. Sign a short bridge contract of 6 to 12 months timed to expire in June, then execute the full term from that clean anchor. Costs slightly more in bridge pricing but resets the cycle permanently.
- Time the migration to a favorable market. Wait for a soft-window pricing environment, then execute a slightly-off-standard term to catch the shift. This is the option that requires the most patience and the most market awareness.
None of this requires acting today. The next renewal cycle is the moment. What matters is having the goal named in advance so that when the renewal quote arrives, the term length gets chosen to move the expiration toward June rather than defaulting to whatever length the incumbent supplier proposes.
