Energy & Sustainability Procurement

How the market works

Energy spend combines a commodity, a regulated delivery service and a set of physical assets that determine how much of both you consume. Electricity and natural gas bills typically include a supply portion, which in many markets can be bought competitively, and a delivery portion set by utility tariffs. Delivery charges often include demand charges based on peak usage in a billing period, which can make up a large share of the bill for sites with short, sharp peaks.

Where supply can be bought competitively, suppliers offer several structures. Fixed-price contracts lock a rate for a term. Index contracts pass through market prices plus a supplier margin. Block-and-index structures fix a portion of expected load and float the rest. Each shifts risk differently between buyer and supplier, and the right choice depends on load shape, budget certainty needs and how actively the organization wants to manage its position.

Beyond the commodity, cost is driven by equipment and operations. Lighting, HVAC systems, building controls and process equipment determine consumption and peak demand. Efficiency upgrades may be self-funded, financed or delivered through performance contracts with energy service companies (ESCOs) that tie project economics to projected savings.

Sustainability adds another layer. Organizations increasingly buy renewable attributes through renewable energy certificates (RECs), supplier green products or power purchase agreements (PPAs), and they need reliable usage and emissions data to report on progress. These are procurement decisions with long tails, and they deserve the same rigor as any other contract.

Where cost and value leak

Bills go unchecked. Utility invoices arrive by the hundreds across sites and accounts. Wrong rate classes, estimated reads, duplicate charges, incorrect tax treatment and late fees are paid without review.

Contracts roll over. Supply agreements expire onto default or holdover rates because no one tracked the end date.

Demand is ignored. Organizations negotiate the commodity price and overlook demand charges that are driven by operating patterns.

Efficiency savings are assumed, not verified. Projects are approved on projected savings, and no one measures whether they arrived.

Sustainability data doesn’t reconcile. Usage for reporting is pulled from different sources than usage on the bill, so the numbers don’t match and confidence erodes.

Illustration: a hypothetical manufacturer with plants, warehouses and offices in several utility territories pays its energy bills through AP with no central review. A bill audit finds two sites on rate classes that no longer match their load, one account still billing after a building was vacated, and a supply contract that lapsed onto a variable default rate months earlier. At the largest plant, most of the delivery cost is driven by demand charges set during brief morning start-ups, which a change in equipment sequencing could reduce without touching the commodity price at all.

Negotiation and sourcing levers

Supply structure — compare fixed, index and block-and-index offers on a like-for-like basis against your load profile and budget needs.
Competitive supplier process — run structured solicitations with consistent terms, timing and pricing formats so offers can be compared.
Contract terms — address bandwidth or swing tolerances, pass-through charges, early termination and renewal notice provisions.
Tariff and rate optimization — confirm each account is on the most appropriate rate class and that demand and power factor charges are understood.
Bill audit and recovery — review invoices against tariffs and contracts, pursue credits and put ongoing validation in place.
Efficiency project sourcing — scope lighting, HVAC and controls upgrades, compare contractors and ESCOs, and write measurement and verification into the agreement.
Renewable options — evaluate RECs, supplier green products and PPAs on price, term, risk and reporting fit, with your legal and tax advisors.

The S2V approach

Potential. We assemble energy spend by site, account and meter, separate supply from delivery and demand, and identify billing errors, lapsed contracts, rate mismatches and efficiency opportunities. The S2V Compass turns that into an evidence-backed opportunity portfolio.

Priority. We rank opportunities by value, feasibility, capital required, time to value and risk. Contract expirations, budget cycles and sustainability commitments shape the S2V Blueprint and the order of work.

Performance. Through the S2V Accelerator, we run supply solicitations, pursue bill recoveries, work with facilities teams on demand and controls, source efficiency projects with verifiable performance terms and structure renewable purchases alongside your advisors.

Value. With S2V Pulse, we track realized results in utility invoices and meter data, verify efficiency savings against a baseline and keep contract expirations on a managed calendar so nothing rolls over by accident.

Data you’ll need

We typically need twelve or more months of utility invoices, supply contracts and confirmations, account and meter lists by site, interval or smart meter data where available, facility square footage and operating hours, equipment inventories for major systems, and any existing sustainability reporting.

The identifiers that break are predictable. Utility account numbers change when accounts are re-issued, meter numbers don’t appear in AP, the same site carries different names in AP, the utility portal and the sustainability platform, and invoices are posted as lump sums without usage or demand detail.

Before analysis, we confirm whether bills, meters and sites can be joined reliably through a common site key, a maintained account and meter register and invoice detail that captures usage and demand. If they can’t, we say so and scope the foundation work separately rather than hiding it inside a fixed fee. Once built, the same foundation serves cost management and sustainability reporting.

Outcomes we target

Accurate bills, validated monthly — errors caught and recovered, with ongoing checks in place.
Supply bought deliberately — contract structures chosen on evidence, with no silent rollovers.
Lower demand-driven cost — peak charges understood and managed through operations and controls.
Verified efficiency savings — project results measured against a baseline, not assumed.
Reliable sustainability data — usage and emissions inputs that reconcile to the bill.
A managed contract calendar — expirations, notice dates and renewal decisions visible in advance.

Every result is tracked to realized value — measured in invoices and operating performance, not negotiated estimates.

Industries where this matters

How we help

Assess — Assess establishes where your organization stands and where value is trapped.
Advise — Advise determines where procurement should go and what deserves resources first.
Execute — Execute turns strategy into implemented results.
Develop — Develop builds your team's capability so results last after the engagement ends.
Sustain — Sustain protects and extends value after implementation.

Frequently asked questions

Do you tell us whether to buy fixed or index energy?

We lay out the commercial trade-offs of fixed, index and block-and-index structures against your load profile, budget certainty needs and risk tolerance, and run a competitive process with suppliers. The decision stays with you. We do not provide investment, trading or hedging advice.

What is a utility bill audit and why does it matter?

It is a line-by-line review of utility invoices against tariffs, contracts and meter data. Rate class errors, estimated reads, duplicate charges, incorrect taxes and late fees are common, and they persist until someone looks for them.

Can you help with renewable energy purchases?

We help you understand the commercial structure of options such as renewable energy certificates, supplier green products and power purchase agreements, compare offers on a consistent basis and negotiate terms. We work alongside your legal, tax and sustainability advisors and do not provide regulatory or investment advice.

How does efficiency fit into procurement?

Lighting, HVAC and controls upgrades reduce consumption and demand, which often matters as much as the price per unit. We help scope projects, compare contractors and energy service companies, and structure performance commitments so promised savings can be verified.

Can you help with emissions reporting data?

We help build the usage and invoice data foundation that reporting depends on, including consistent meter, site and account identifiers. We do not prepare regulatory filings or provide assurance, but we make the underlying data reliable enough for the people who do.
