Avoiding Penalties

Regulations do not only set standards—they also enforce them with penalties and incentives. Many states require utilities and energy suppliers to meet Renewable Portfolio Standards (RPS). Failure to comply leads to Alternative Compliance Payments (ACPs), which act as fines. Telecom operators may fall under these rules if they operate in regulated areas.

Operators can avoid penalties by generating renewable energy or purchasing Solar Renewable Energy Credits (SRECs). Each SREC represents 1 megawatt-hour of solar electricity. By producing solar power onsite, operators generate SRECs, which they can sell to utilities that need credits to meet RPS requirements. This creates a financial incentive for compliance.

Note: By investing in solar energy, telecom operators not only meet regulatory requirements but also gain financial benefits and avoid costly penalties.

8. Equipment Longevity

Stable Power Supply

Telecom equipment depends on a steady flow of electricity to function at its best. Power fluctuations can cause serious problems for sensitive devices inside telecom cabinets.
