RESILIENCE & LIABILITY PROTECTION FOR CARE FACILITIES

Ensuring critical heating and hot water supply during grid failure

A joint offering from TRYBA Solar & XTRA-E^® (Green Shark Group)

The decisive hour is NOW

Imagine: It's 4 a.m. in January. The power grid fails. The heating circulation pumps fall silent. Within 90 minutes, the temperature in residents' rooms drops below 18 °C. What follows is not a hypothetical scenario – it is the real consequence of the Berlin blackout in 2023, which forced several nursing homes to evacuate immediately.

This audit study shows you concretely:

Which legal obligations you MUST fulfill NOW – regardless of KRITIS status
How to systematically exclude personal liability risks for nursing home management
Why a diesel-based emergency power supply with PV-battery backup is the only future-proof solution

Resilienz Audit für Pflegeeinrichtungen – Notstromversorgung und Haftungsschutz

1. RISK ANALYSIS: When the heat goes, the liability trap begins

1.1 The physical reality: Cold kills faster than darkness

According to DIN SPEC 1946-7:2022-05, section 5.3.1:

“In facilities with people in need of care, a minimum temperature of 20 °C must be maintained in living areas for at least 24 hours even in the event of failure of the main power supply.”

Without emergency power for heating circulation pumps and hot water preparation, a critical condition occurs within a very short time:

0–60 minutes: Temperature drop in heating circuits → cold radiators
60–120 minutes: Room temperature below 18 °C → acute hypothermia risk for bedridden residents
>120 minutes: Obligation to evacuate according to state nursing home laws (e.g., § 11 HeimG BW)

1.2 The legal reality: Personal liability of decision-makers

According to BGB § 823 Paragraph 1:

“Whoever intentionally or negligently unlawfully injures the life, body, health [...] of another is obliged to compensate the other for the resulting damage.”

According to Occupational Health and Safety Act § 3 Paragraph 1:

“The employer is obliged to take the necessary occupational safety measures, taking into account the hazards to employees and third parties.”

The consequence: Failure to provide for heat supply during a power outage is considered by courts as a grossly negligent breach of duty – with personally liable management and nursing home leadership. The Berlin blackout has shown: Insurance provides no protection if preventive measures are demonstrably omitted.

2. LEGAL FRAMEWORK: Precise classification beyond KRITIS misunderstandings

2.1 Clear positioning: Nursing homes are NOT KRITIS facilities – but...

According to BSI-KritisV § 2 Paragraph 1 No. 7:

“KRITIS facilities in the health sector are hospitals with more than 30,000 inpatient treatment cases per calendar year.”

Nevertheless, stricter obligations apply:

State building codes (e.g., § 15 MBO): Ensuring vital functions during power outage
Nursing Home Minimum Construction Ordinance (HeimMindBauV): Structural minimum requirements for protection areas
Operational Safety Ordinance Appendix 2: Regular testing of safety-related equipment

2.2 The “Resilience Umbrella Act”: New dimension of duty of care

Since the entry into force of the Act to Strengthen Information Technology Security (IT-SiG 2.0) in May 2024:

According to § 8b BSIG n.F.:

“Operators of special facilities must take appropriate measures to maintain functionality in the event of disruptions to the energy supply and document these in a resilience plan.”

Nursing homes are among the “special facilities” according to § 2 No. 15 BSIG – regardless of KRITIS status. The documentation obligation for resilience measures is therefore legally binding.

3. TECHNICAL AUDIT: The hybrid emergency power architecture according to VDE standard

3.1 System structure with clearly defined load separation

CRITICAL LOADS (Safety power)

Consumers: Heating circulation pumps, hot water preparation, emergency lighting, medical devices

Normative requirement: DIN VDE 0100-710: maximum transfer time 15 seconds

Supply technology: Diesel generator with automatic start

NON-CRITICAL LOADS (Substitute power)

Consumers: General lighting, food refrigeration, sanitary areas

Normative requirement: DIN VDE 0100-560: minimum autonomy time 120 minutes

Supply technology: Battery storage with optional PV charging

According to DIN VDE 0100-551:2017-02, section 551.7.2: “The safety power supply must start automatically within the time prescribed for the respective application. For heating systems in care facilities, a maximum transfer time of 15 seconds applies.”

3.2 Sizing according to facility size (real project data)

Small facility

20–40 residents

Critical load: 18–28 kW
Generator output: 40–60 kVA
Battery capacity: 25–40 kWh
Emergency diesel reserve: 24 hours full load (approx. 1,200 liters)

Medium facility

41–80 residents

Critical load: 35–55 kW
Generator output: 80–125 kVA
Battery capacity: 60–90 kWh
Emergency diesel reserve: 48 hours full load (approx. 2,800 liters)

Large facility

81–150 residents

Critical load: 70–110 kW
Generator output: 160–250 kVA
Battery capacity: 120–180 kWh
Emergency diesel reserve: 72 hours full load (approx. 5,500 liters)

Note: The sizing is based on hospital standards according to the recommendation of the German Medical Association (2022) – 24 hours minimum reserve, expandable to 72 hours for large facilities.

3.3 Safety-related protection of the fuel storage

According to TRBS 3146/TRGS 746 (2016):

“Stationary diesel storage tanks > 1,000 liters must be fire-protected (F90), secured against overfilling, and equipped with leak detection. Minimum distance to living areas: 5 meters.”

Our solution: Integrated tank containers with double-walled construction, automatic leak monitoring, and remote alarming – approvable according to Federal Immission Control Act §13.

4. YOUR FINANCING OPTIONS: Tailor-made paths to resilience

🔒 COMPLETE SOLUTION FROM A SINGLE SOURCE

Purchase / Leasing / Financing / IAB

Your advantage: 100% ownership – full control over your system

Purchase: Immediate activation of the investment deduction (IAB) – tax advantages within the current year
Leasing: Preserve your liquidity – predictable monthly installments without down payment

6. RECOMMENDATION FOR ACTION: Three steps to immediate risk minimization

1

Step 1 – Schedule an audit appointment

Within 5 working days, you will receive a site-specific load assessment with a clear separation of critical and non-critical consumers – free of charge and without obligation.

2

Step 2 – Document the resilience plan

We create the legally required resilience plan for you according to § 8b BSIG – ready for submission to supervisory authorities and insurers.

3

Step 3 – Installation within 90 days

From approval to commissioning: a maximum of 12 weeks. Your liability gap closes – before the next blackout comes.

CONCLUSION: Not a question of IF – but WHEN you act

The technology is available. The standards are clear. The legal obligation is undisputed. What remains is a single decision:

Do you want to have to explain to residents, relatives, and in court why you forewent a proven emergency power solution in the event of a crisis?

With TRYBA Solar & XTRA-E^®, you close this gap – individually, standards-compliant, and with the security of a partner who has been securing critical infrastructure for over a decade.

The next hour decides not about technology. It decides about responsibility.
