Focus on what can change in the third year
Review lease expiry, planned equipment replacements, expected production, potential asset sales and electrification plans. A three-year supply contract may extend past a known operational decision. Ask how relocation, material load changes and assignment are handled before treating the extra year as harmless budget protection.
For a growing facility, verify whether forecast additions are covered at the quoted structure or repriced later. For a shrinking operation, examine minimum quantities, take-or-pay provisions and tolerance. These terms can matter more than a small two-versus-three-year rate difference because the supplier may have priced a specific expected load.
Keep the two-year comparison and third-year decision separate
Calculate the two offers over their common first twenty-four months using the same consumption and scope. Then isolate what is being committed for the additional twelve months. Comparing total dollars alone would naturally make the longer contract look more expensive simply because it includes more service. A meaningful review aligns the time horizon first.
The alternative to a thirty-six-month contract is not necessarily zero cost in year three. It is an unknown future purchase, possibly under a different market and contract. Model that future cost with explicit scenarios. Do not represent the present two-year rate as a guaranteed renewal price for the third year.
Hypothetical threshold for the additional year
Suppose annual electricity use is 200,000 kWh. An invented twenty-four-month price of $0.10 produces $40,000 over two years. A hypothetical thirty-six-month price of $0.098 produces $58,800 over three years. To match that three-year total after buying the two-year offer, year three would need to cost $18,800, or $0.094 per kWh.
A year-three price above that threshold favors the quoted three-year case in this simplified arithmetic; a lower one favors the two-year case followed by that assumed purchase. Neither outcome is predicted. Fees, changing usage, taxes and excluded delivery components need separate treatment, and the threshold changes when those assumptions change.
Examine commitment as well as certainty
Ask whether fixed means all supplier components or only energy, and whether regulatory changes can alter charges. Confirm the notice window for both terms and keep a reminder well before it. A longer term does not eliminate renewal administration; it postpones it while adding time during which staff or ownership can change.
Present the decision with the common-period costs, the third-year threshold and the operating changes that would cause concern. Retain the actual quote documents and expiry times. This gives management a concrete choice between commitments, rather than a general claim that a particular term length always protects against the market or produces savings.
Questions & answers
Does a longer fixed term guarantee lower spending?
No. It fixes only stated components and can add commitment risk. Usage, fees and exclusions still affect total cost.
