Mechanism

How Peak Shaving and Section 19 Grid Fees Structurally Reduce Costs

Grid fees account for ~40% of the industrial electricity price. The largest portion is determined by a single 15-minute peak—for all 12 subsequent months.

Peak Shaving

The battery storage system automatically discharges when a peak load is imminent. The 15-minute average remains below the billing threshold → The demand charge permanently decreases.

Effect from commissioning – no production intervention. Capacity price = grid fee component based on the highest 15-minute average in the billing year.
RLM companies (§17 Para. 6 StromNEV · ene’t GmbH, Jan. 2024)
Load Shifting - §19 Atypical Grid Usage

Automatic shifting of load to time windows outside the grid operator's peak load times (HLZ). Prerequisite for §19 Paragraph 2 Sentence 1 of the StromNEV (Electricity Grid Fee Ordinance).

The CUBE EfficiencyUnit coordinates peak shaving and load shifting fully automatically — §19 compliance always takes precedence over FTM marketing.
§19 - Compliance Documented · Peak Shaving Effective from Day 1 of commissioning
Fully automatic. No intervention in production operations. Compliance is documented in an audit-proof manner.
Qualification

Who qualifies for §19 atypical grid usage?

Three basic requirements — CUBE BatterySizer checks all three free of charge from your load profile.

01
RLM meter
With an annual consumption of approximately 100,000 kWh. Metered demand measurement — a prerequisite for load profile analysis and §19 application.
02
Operating hours > 2,500 h/year
Annual consumption ÷ Peak annual load. The load profile must be uneven.
03
Uneven load profile
Inrush currents, shift work, e-fleets, seasonal peaks. The more pronounced the peak, the greater the leverage.

RLM Meter · Peak Loads · §19 Potential
Economic efficiency

Three factors determine the business case

01
Performance premium

€60–440/kW/year depending on the network operator, network level, and region. The leverage: one saved kW peak saves this amount permanently.

02
Peak load profile

Magnitude and frequency of the 15-minute peak. The rarer and higher the peak, the greater the peak-shaving potential.

03
Storage Sizing

Load to be cut [kW] × Peak duration [h] × Safety factor = Minimum capacity [kWh]. CUBE BatterySizer calculates over 250 operating variants.

Does peak shaving qualify as an ISP service?

This applies if your company is on the KUEBLL list: Companies that receive government subsidies to reduce electricity costs must reinvest 50% of the subsidy in decarbonization or flexibility measures. Battery storage systems are explicitly recognized.

Typical objections

The most common objections—answered directly

„§19 expires in 2028 — is the investment still worth it?”
Peak Shaving functions independently of Section 19. The power price savings (€60–€440/kW/year) are permanent — without regulation. Section 19 is the additional lever until 2028. From 2029, AgNes will take over with dynamic price signals. Those who invest now benefit from both systems.
„We do not have a pronounced peak load.”
The CUBE BatterySizer checks this based on your load profile — free of charge, in 1-2 weeks. The analysis frequently identifies peaks that are not visible internally: inrush currents, shift changes, seasonal peaks. If the analysis shows no economic peak: no offer, no commitment. The analysis costs nothing — and we tell you the truth.
„We don't want any debt on our balance sheet.”
With the CPFS BESS Contracting, the investment remains entirely with CUBE. Off-balance sheet under IFRS. No capitalization. 25% of the net market proceeds from Day 1 — no CAPEX, no balance sheet risk.
„Can we combine peak shaving and FTM revenues?”
Yes—but priorities matter. Section 19 compliance and peak shaving always take precedence. FTM (FCR, aFRR, mFRR as a supplementary channel, arbitrage) only runs during time slots without HLZ. The CUBE EfficiencyUnit coordinates this fully automatically, without any intervention in production.

Frequently Asked Questions

Peak Shaving & Section 19 — Answers for Decision-Makers

The battery storage system automatically discharges in anticipation of a peak load. The 15-minute average remains below the billing threshold, and the demand charge permanently decreases. No production intervention is required; effective from commissioning.
Section 19(2), sentence 1 of the StromNEV applies if the annual peak load falls outside the peak load period of the local distribution network operator. Grid fee savings of up to 80 % are possible. Application deadline: September 30 of each year. Expires: December 31, 2028.
60–440 €/kW/year depending on the grid operator, grid level, and region. A single 15-minute peak sets this price for all subsequent 12 months—regardless of whether it repeats.
CUBE BatterySizer calculates this site-specifically from load profile data. CUBE reference project: 3,811 kW annual peak, capacity price €142.87/kW/year, savings of €119,415/year through peak shaving.
AgNes will take effect on January 1, 2029 — dynamic, time-varying grid tariffs (BNetzA BGK-25-01-1#3). The CUBE EfficiencyUnit automatically responds to AgNes signals. No hardware replacement is necessary.
RLM meter (from ~100,000 kWh/year), operating hours >2,500 h, uneven load profile. Minimum displacement ≥100 kW, de minimis limit ≥€500/year. CUBE BatterySizer checks for free.
Full-service: free load profile analysis, manufacturer tender (min. 3 offers, LCOS-rated), construction and commissioning, annual §19 process (K5RIDS1 by 09/30), 24/7 operation, AgNes conversion 2029.
Yes. Section 19 compliance and peak shaving always take priority—FTM (FCR, aFRR, mFRR as a supplementary channel, arbitrage) only runs during time slots without HLZ. CUBE EfficiencyUnit coordinates this fully automatically.
