Why Data Center Power Reliability Matters

Reliable power keeps every transaction, system, and connection in a data center running without interruption.

1. Downtime Costs More Than Repairs

Every minute of unplanned downtime costs large data centers thousands in lost productivity and transactions.
Recent reports show that most significant outages now exceed $100,000, with 16% surpassing $1 million in total impact.


Power disruptions can damage equipment, overload UPS systems, and create lengthy recovery times.
Rehlko generators, backed by BCEW service, provide immediate standby power to prevent outages and data loss.

2. Compliance Requires Proven Backup Power

Regulatory standards like NFPA 110 and Uptime Institute Tier III/IV require tested emergency systems.


The same data also pointed out that power issues remain the #1 cause of significant data center outages—cited in 52% of cases, far ahead of cooling at 19%.

A failed inspection can lead to penalties or insurance gaps.  BCEW’s certified maintenance keeps your Rehlko generator inspection-ready and fully up to code year-round.

3.  Power Quality Impacts Performance

Voltage stability is essential for IT efficiency. Even small fluctuations can cause reboots, data errors, or UPS faults.


Rehlko generators deliver clean, regulated power that preserves uptime, supports sensitive loads, and helps maintain consistent system performance


Bay City Electric Works helps data centers remain operational, compliant, and efficient—no matter what the grid is doing.


Because when uptime is your promise, reliable power isn’t optional.

Reliable Power Systems Backed by BCEW Expertise

Reliable performance depends on both strong equipment and the people who maintain it. BCEW partners with Rehlko to align precision engineering with hands-on service expertise.

We Support

Data centers and colocation facilities

Enterprise and cloud IT operations

Telecom and network hubs

Financial, municipal, and government systems

Our certified teams handle design, installation, testing, and 24/7 support to keep your infrastructure running.

Here’s how we make that reliability happen.

How We Keep Your Data Center Powered

BCEW’s process focuses on long-term reliability, safety, and measurable uptime improvement.

Custom Engineering for Your Facility

We size and configure each Rehlko system for your exact electrical load and redundancy model (N, N+1, or 2N).
This prevents underperformance, reduces fuel use, and allows for future expansion without redesign.

Precise Installation and Testing

Our technicians follow UL 2200 and NFPA 110 standards for every setup.
We complete load bank and electrical testing to confirm voltage stability, frequency control, and transfer reliability under real conditions.

Preventive Maintenance That Reduces Outages

We tailor maintenance schedules to your usage—not a one-size-fits-all calendar.
Routine inspections, coolant analysis, and ATS testing reduce emergency repairs by up to 60% and extend generator lifespan by 30%.

Real-Time Monitoring and Support

With optional remote monitoring, you receive alerts and performance updates in real time. Our service teams are available day and night for rapid response across California, Nevada, and Hawaii.

 

Our process keeps your systems efficient, reliable, and ready for every audit or power event.

Rehlko generators deliver performance while supporting sustainability goals. Moreover, Rehlko’s next-generation engines are designed for multi-fuel compatibility, giving you flexibility and compliance assurance.

They can operate on:

Diesel (Tier 4-certified)

Renewable diesel (HVO)

Natural gas or propane

Emerging fuels like hydrogen

BCEW helps you select the right configuration to meet environmental and operational needs, especially in California, where CARB and AQMD standards are among the strictest nationwide.

Generator Models and Options

Whether your facility supports a single room or an enterprise-scale data hub, BCEW provides the right Rehlko model for your load profile.

Many customers still recognize these as Kohler commercial diesel generators, now part of the Rehlko lineup, carrying forward the same performance standards.

Frequently Asked Questions

What is Rehlko, and how does it relate to Kohler Power Systems?

Kohler Power Systems rebranded to Rehlko in 2024. The same engineering, technology, and service network continues under the new brand name.
Bay City Electric Works remains an authorized Rehlko partner, providing sales, installation, and service across California, Nevada, and Hawaii.

Why are Rehlko generators used in data centers?

Rehlko generators are designed for continuous, mission-critical power.
They provide fast load acceptance, clean voltage output, and Tier 4 emissions compliance, meeting the high reliability standards required for data centers and IT facilities.

How do data centers stay powered during outages?

When utility power fails, a Rehlko standby generator automatically starts and transfers load through an ATS (Automatic Transfer Switch).

It works with UPS systems to maintain seamless operation until grid power is restored.

How often should data center generators be tested or serviced?

BCEW recommends monthly no-load tests, semiannual load bank testing, and annual inspections to verify system performance and compliance.

Our maintenance plans include all testing, documentation, and calibration to keep power systems reliable year-round.

Can BCEW service older Kohler or Rehlko generators?

Yes. BCEW services legacy Kohler Power Systems units and all current Rehlko models.

We provide diagnostics, part replacements, software updates, and compliance upgrades to extend system life and performance.

Do Rehlko generators meet Tier 4 and data center standards?

Yes. Rehlko KD Series generators are Tier 4 Final certified and meet or exceed Uptime Institute Tier III–IV, NFPA 110, and UL 2200 standards for data center reliability and safety.

How can I request data center generator service or consultation?

You can request service, schedule a diagnostic assessment, or ask for a maintenance plan through our Contact page.

BCEW responds quickly and provides 24/7 support across California, Nevada, and Hawaii.

What size generator does a data center need?

It depends on your facility’s load requirements, redundancy model (N, N+1, or 2N), and operating tier. BCEW can help size your Rehlko generator system to ensure proper capacity and compliance with Tier III–IV standards.
