Seven items

Where large energy users leave money on the table today, without seeing it.

Industrial and mid-sized customers usually overpay not because their terms are poor, but because the main levers are left unused.

IntervalMeter type
15 minMeasurement interval
12 monthsLock-in from a single peak
Demand charge
Load peaks drive the demand charge

With interval meters the most expensive item is not consumption, it is the highest 15-minute peak. A single uncontrolled peak sets your demand charge for 12 months.

Procurement
A missed moment of purchase

Buying in the wrong quarter quickly costs one to two cents more per kWh. At 1.8 GWh that is €18,000-36,000 a year.

Load profile
Opaque load profiles

Without a load profile analysis there is no basis for negotiating terms. You negotiate blind, the supplier knows your data better than you do.

Terms
Preferential terms left unused

Tranche purchasing, index-linked contracts, terms through buying groups, no standard sales channel offers you these actively.

Deadline
Automatic contract renewal

Missed notice periods tie you for 12 months to terms that stopped being market-appropriate long ago. Nobody reminds you.

Management
No active energy management

In mid-sized companies energy is often handled on the side. There is neither the time nor the tooling for continuous market monitoring and load optimisation.

Grid fee
Hidden grid fees and levies

Atypical grid use, special cases under § 19 StromNEV, avoided grid fees, many levers go unused simply because nobody checks them.

Large-user exclusive · load profile deep dive

Load profile optimisation: where the lever really sits.

With interval meters it is not consumption that determines your energy costs, it is the structure. We analyse your load profile systematically for four levers that never appear in conventional tariff comparisons:

Peak load reduction:
A single uncontrolled 15-minute peak sets your demand charge for 12 months.
Atypical grid use (§ 19(2) StromNEV):
If your load lies predictably outside the peak-load windows, you qualify for reduced grid fees.
Special cases under § 19 StromNEV and avoided grid fees:
Self-generation, CHP, PV, many levers go unused simply because nobody checks them.
Tranche purchasing:
Buying your volume in tranches across the year, this evens out market volatility and reduces purchasing risk.

Purchasing structure

Pooled purchasing through a buying group.

It is not the supplier that changes, it is the purchasing structure. Pooling instead of individual negotiation.

Conventional mid-market purchasing runs as a bilateral negotiation with one to three suppliers. Through the GSP buying group, the volumes of dozens of companies are pooled, which means you buy at a level of terms that energy suppliers otherwise offer only to corporate customers.

Reversal of risk · under contract

Compensation instead of excuses, set down in the contract.

Reversal of risk is not a marketing promise here. It is part of the engagement contract and enforceable in law.

The engagement contract defines precisely what we deliver: the cheapest price available within the buying group, a written analysis of terms you can follow, personal support with response times under 48 hours, and annual optimisation cycles. Should we fail to keep these commitments, you have a contractually fixed claim to compensation, not an act of goodwill, but an enforceable clause.

3 clausesin the engagement contract
§ 5Results guarantee
48 hoursResponse time
Clause 1

Best-price commitment not met

A claim to compensation for the difference over the whole contract term, as soon as you demonstrate that a cheaper price is available under the same model.

Clause 2

Terms differ from the offer

A claim to compensation if the written offer is not honoured when the contract is implemented.

Clause 3

Personal support not provided

A contractual penalty clause if the named adviser or the response times are not delivered.

Compensation clause, read the full clause

If we do not deliver the saving we have committed to, you have a contractual claim.

Extract from the engagement contract, § 5 (results guarantee):

  1. DGfE/GSP undertakes to secure by contract a saving specifically stated in the initial analysis letter (measured at the time of comparison).
  2. If that committed saving is demonstrably not achieved in the following year, the client has a contractual claim to compensation for the difference out of the brokerage margin.
  3. Conditions: a complete broker's letter of authority, complete handover of data (load profile/bill) and no contract changes initiated by the client during the term.
  4. The claim is made in writing on presentation of the following year's bill and is settled within 30 days.
  5. Force majeure, tariff changes imposed by regulation and consumption deviations of more than ±15% against the initial analysis figure are excluded.

Not a marketing promise, contract text from § 5 of our standard engagement contract.

Detailed clauses and compensation amounts are set out transparently in the engagement contract · available on request for prior review by your legal department.

Q1What does the initial analysis cost?

The complete initial analysis, load profile analysis, market comparison, written assessment document, is free of charge for you. We are paid solely by the chosen supplier once a contract has been successfully arranged, through a commission that is standard in the industry and priced into the tariff. If you do not switch after the assessment, no costs arise at all.

Q2How does group-level purchasing work in practice?

We work with established energy purchasing companies which, by pooling the volumes of many companies, conclude negotiated tariff contracts with suppliers. Those terms are typically well below conventional negotiated contracts for mid-sized companies. You become a contracting party on those preferential terms without having to reach the volume threshold on your own.

Q3What happens to our load profile, is it shared with third parties?

No. Your load profile is used solely for our internal analysis and the market comparison. Processing is GDPR-compliant, on servers in Germany, with no resale, no third-party use, no transfer to US clouds and no AI analysis by third-party services. On request we sign an NDA before any data is released. Once the mandate is completed or declined, data is deleted on request.

Q4Is GSP GDPR-compliant, and where are the servers?

Yes, fully GDPR-compliant. Data is processed exclusively on servers in Germany. A data processing agreement (AVV) is available on request before data is released. No data is passed to third countries, there is no Schrems II exposure, and no tracking cookies transfer data abroad.

Q5How long does our existing contract still run, and does a check make sense now at all?

That is precisely part of our initial analysis. We check the contract term, notice periods and automatic renewal mechanics from your current bill. You receive a written switching schedule: “You can switch on [date], for which you must give notice by [date].” Even if you are tied in for a long time, we create transparency for the next moment of purchase, and take over monitoring the deadlines, so you do not run into the next automatic renewal.

Q6What exactly does this cost us, are there hidden fees?

No hidden fees at all. No advice, brokerage or set-up fees. We are paid by the supplier through a commission priced into the tariff, the same mechanism conventional energy brokers use. The decisive difference: the tariff you obtain through the buying group is still well below the open market, because you are buying at a corporate level of terms. This is set out transparently in the engagement contract.

Q7We already have an energy adviser or purchasing service provider, is a comparison worth it?

All the more so. A counter-check is standard practice in the industry and does no harm to an existing relationship. We supply a written assessment that you can compare internally or with your current provider. In around 80% of cases we find relevant additional levers, particularly in load profile optimisation and purchasing structure, which conventional brokerage models do not cover.

Q8We are tied into a contract, what does a check achieve now?

Checking now creates transparency for the next moment of purchase. We analyse your contract position, document the notice periods and develop a strategy for the optimal switching date. That way you are prepared when your current contract ends, instead of buying under time pressure.

Q9What does the broker's letter of authority mean in practice, and how much control do we keep?

The broker's letter of authority allows us to communicate with suppliers on your behalf, negotiate terms, review contracts, monitor deadlines and carry out annual optimisation. You remain the contracting party and the decision-maker at all times, we recommend, you decide. The letter of authority can be revoked in writing at any time, with no notice period and without giving reasons.

Q10How is the best-price guarantee secured operationally?

It is fixed by contract: through our model you obtain the cheapest price available on the market within the buying group. Should we fail to keep that commitment, you have a contractually defined claim to compensation. This clause forms part of the engagement documents and part of our reversal of risk, and your legal department can review it beforehand on request.

Q11How quickly do we see results once we release the data?

The initial analysis follows within 5 working days. For extensive load profile datasets (several sites, multi-utility consumption) up to 10 working days. You receive a written assessment document with specific comparisons of terms and recommendations for optimisation, not a PowerPoint sales presentation, but an analysis you can follow.

Q12What data do you actually need?

As a minimum: your electricity bill for the last 12 months. Ideally: an interval load profile as CSV/Excel covering at least 12 months (15-minute values), your current electricity supply contract and, where relevant, data on self-generation (PV, CHP) and avoided grid fees. The more complete the data, the more precise the optimisation levers.

Q13The spot market, is that part of your model?

Our standard model is based on fixed-price and tranche structures through the buying group. Spot-market models are possible in specific situations, but they are discussed individually and after a risk analysis, they are not applied across the board. In the first call we establish which purchasing structure suits your consumption profile.

Q14Who is my point of contact, and how quickly do they respond?

You are assigned a named energy adviser with a direct line and a personal email address. A response within 48 hours, and faster during critical purchasing windows. No hotline, no changing case handlers. During holiday or illness there is a named deputy.

Q15What distinguishes you from conventional energy advisers or tariff comparison services?

Three things. First, we do not arrange standard negotiated contracts but buying-group terms. Second, we carry out active load profile and structural analysis, not just a price comparison. Third, we back our best-price commitment with contractual compensation. Conventional tariff comparison services offer none of these three.

Q16Can we have our legal department review the compensation clause beforehand?

We positively encourage it. Before you engage us, we provide the full engagement contract including the compensation clause for review. We even recommend that your legal department comment on the clause, anyone with a fair model has nothing to fear from a prior review.

Q17What happens to our data in the age of AI, is it used for model training?

No. Your load profile and contract data are used solely for your individual analysis, not for model training, not in aggregated databases, and not for third parties. The assessment is carried out by your personal adviser using our own market database, not by external AI services. Fixed by contract on request.

Terms are volatile. Your contract is not.

We take on a limited number of new industrial mandates each quarter, so that we can guarantee the depth of the load profile analysis and personal support.

Energy terms change daily, but automatic contract renewals tie you in for 12 months. In industrial consumption bands, missing the moment of purchase quickly costs six figures.

We analyse your load profile free of charge and without obligation. You lose nothing. What we may find: a material item in your P&L.
