This isn’t a dream. It’s real for Bangladeshi homeowners and businesses through the Net Metering Guidelines 2025.

As the nation pushes for 20% renewable energy by 2030, your rooftop can become a mini power plant—cutting costs and generating income.

Skip the policy jargon. Here’s what you need to know to turn your rooftop into revenue.

What Exactly is Net Metering?

In simple terms, Net Metering is a billing mechanism that allows you to get credit for the electricity you add to the national grid.

Here’s how it works:

1. Generate Power: You install a renewable energy system, like solar panels, on your property to produce electricity for your own use.
2. Use What You Need: Your home or business runs on this clean, free energy during the day.
3. Export the Surplus: If you produce more electricity than you consume, the excess power is automatically sent to the national distribution grid.
4. Get Credited: Your electricity bill for the month is credited for the amount of power you supplied to the grid. You only pay for the “net” amount of electricity you drew from the grid.

This entire process is managed by a special bi-directional “Net Meter” that separately records the electricity you import from the grid and the electricity you export to it.

The Best Part: Rollover Credits and Cash Payments!

What happens if you export more electricity than you import in a month?

• Credit Rollover: The excess electricity is carried forward as a credit to your next month’s bill.
• Settlement Period: This system operates on a three-month “settlement period” that ends in March, June, September, and December. If, at the end of this period, you still have accumulated credits, your distribution utility will pay you for those units at a government-determined bulk tariff rate!

CAPEX vs. OPEX: Which Solar Investment Model is Right for You?

The guidelines offer two flexible models for setting up your renewable energy system.

1. The CAPEX (Capital Expenditure) Model

This is the straightforward ownership model.

• How it works: You invest your own funds to purchase and install the solar system.
• Who it’s for: Individuals or businesses who want to make a long-term investment and reap the full financial benefits of the system themselves.

2. The OPEX (Operational Expenditure) Model

This model is perfect if you want the benefits of solar without the upfront investment.

• How it works: A third-party investor company installs a solar system on your rooftop at their own cost. You then sign an agreement to buy the electricity generated by the system from them.
• Key Benefits:
  • There is no investment risk for the electricity consumer.
  • The OPEX investor handles all installation, operation, and maintenance.
  • The tariff you pay the OPEX investor is typically lower than the retail tariff of your utility company, guaranteeing savings from day one.
• Agreement: This model requires a tripartite agreement between you (the consumer), the OPEX investor, and the distribution utility.

Are You Eligible for Net Metering?

You can apply for a net metering connection if you meet these key requirements:

• You must be a legitimate, active consumer of a distribution utility.
• You must have no outstanding electricity bills at the time of your application.
• The system must generate electricity from a renewable source (e.g., solar).
• You must either own the property or have formal permission from the owner to install the system.
• Even if you installed a rooftop solar system before these guidelines were introduced, you can apply to have your old system converted to the net metering framework.

The facility is available for a wide range of consumer categories across all voltage levels, including:

• Low Tension (LT): Residential, Irrigation, Small Industry, Commercial & Office, etc..
• Medium Tension (MT): Residential, Commercial, Industrial, etc..
• High Tension (HT): General Use, Commercial, Industrial.
• Extra-High Tension (EHT): All consumer categories.

How Big Can Your System Be?

The guidelines set clear limits on the capacity of your renewable energy system:

• The system’s AC capacity cannot be greater than your sanctioned load from the utility.
• For consumers connected at medium voltage (11kV) or higher, the system capacity cannot exceed 80% of the rated capacity of your transformer.
• Want to go bigger? If you wish to install a system larger than your sanctioned load, you can submit a special application. A committee will review the grid stability and the Power Division will make a final decision.

The Application Process: Step-by-Step

The government has streamlined the application process to be efficient and time-bound.

1. Application Submission: You can apply either by submitting a hard copy or through the online portal (https://nem.powerdivision.gov.bd). If you’re opting for the OPEX model, you must first complete your agreement with the investor company before applying to the utility.
2. Utility Approval: The distribution utility will review your application and issue an approval letter within 10 working days.
3. System Installation: After getting approval, you have a maximum of 8 months to complete the installation of your system.
4. Inspection & Testing: Once installed, you’ll submit a system checklist and request the utility to inspect and test the system to ensure it meets all technical standards.
5. Final Agreement & Connection: After a successful inspection, you will sign the final Net Metering Agreement with the utility within 15 working days. This signing date marks your Commercial Operation Date (COD), and from this day, your net metering journey begins!

Meters determine how much electricity you consume, how much you export to the grid, and how much you save. In Bangladesh, not all types of meters are used in practice—only a few are recognized by the Bangladesh Power Development Board (BPDB), Bangladesh Energy Regulatory Commission (BERC), and distribution companies (DESCO, DPDC, BREB, etc.).

Let’s look at the main types of meters used in Bangladesh’s solar industry.

1. Net Meter

The most widely used system in Bangladesh is Net Metering, introduced officially in 2018 by the government’s Net Metering Guideline.

• How it works: A net meter records both the electricity you consume from the grid and the excess energy your solar system exports. At the end of the billing cycle, your net usage is calculated (import minus export).
• Why it matters: This system allows solar users to reduce their electricity bills while still staying connected to the grid.
• Where it’s used: Universities, factories, commercial buildings, and large institutions with rooftop solar installations.

2. Bi-Directional Meter (Two-Way Meter)

In Bangladesh, bi-directional meters are installed for grid-tied solar projects. These meters separately measure:

• Import: Electricity taken from the grid.
• Export: Surplus solar electricity sent back to the grid.
• Why it matters: Offers clear, transparent data on both consumption and export, which is crucial for billing and financial reporting.
• Where it’s used: Almost all grid-tied solar systems under DESCO, DPDC, BPDB, and REB projects.

3. Smart Net Meter (Emerging in Bangladesh)

Although still in the early stages, some distribution companies in Bangladesh are beginning to use smart net meters with digital communication features.

• How it works: Just like a net meter, but with real-time monitoring options for both customers and utilities.
• Why it matters: Ensures accuracy, reduces disputes, and allows customers to track their solar performance through mobile or web platforms.
• Where it’s used: Pilot projects in urban areas and large industries.

What About Other Types of Meters?

Meters like gross meters or prepaid solar meters are not common in Bangladesh. The government’s focus is on net metering because it balances consumer benefit and grid stability.

Why Meters Are Crucial for Solar Projects in Bangladesh

• Lower Electricity Bills: By exporting surplus power to the grid.
• Transparency: Clear records of import and export prevent billing disputes.
• Investor Confidence: Especially important in OPEX solar models, where investors rely on meter data to calculate returns.
• Government Compliance: Only approved meters ensure your system qualifies under net metering guidelines.

১। অর্থনৈতিক হিসাব
ধরা যাক, আপনার কারখানার মাসিক বিদ্যুৎ বিল = ১,০০,০০০ টাকা

➤ বিদ্যুতের ইউনিট প্রতি দাম = ১০ টাকা

➤ তাহলে আপনি মাসে ব্যবহার করছেন:
১,০০,০০০ ÷ ১০ = ১০,০০০ ইউনিট বিদ্যুৎ
➤ দিনে প্রয়োজন:
১০,০০০ ÷ ৩০ ≈ ৩৩৪ ইউনিট/দিন

এখন – এই ৩৩৪ ইউনিট/দিন আপনি যদি সোলার থেকে পান, তাহলে পুরো বিল শূন্য হয়ে যাবে। (নেট মিটারিং – আপনার প্রয়োজনের অতিরিক্ত বিদ্যুৎ জাতীয় গ্রীডে বিক্রির মাধ্যমে)

একটি ১ কিলোওয়াট (KW) সোলার সিস্টেম দিনে গড়ে ৩.৬ ইউনিট বিদ্যুৎ দিতে পারে।
➤ ৩৩৪ ইউনিট পেতে লাগবে:
৩৩৪ ÷.৩.৬ =.৯৩ KW  সোলার সিস্টেম

প্রতি KW ইনস্টল খরচ ≈ ৩৫,০০০ টাকা হলে (প্রকল্পভেদে ভিন্ন হতে পারে)
➤ ৯৩ KW × ৩৫,০০০ টাকা = ৩৩ লাখ টাকা

অর্থাৎ, আপনি ২.৯ বছরের বিদ্যুৎ বিল (১,০০,০০০ × ৩৩ মাস = ৩৩ লাখ) একবারে ইনভেস্ট করলে

➤ পরবর্তী ২৭.৫ বছর আপনি প্রায় ফ্রি বিদ্যুৎ পাচ্ছেন!

বিঃদ্রঃ বর্তমান সরকার নেটমিটারিং সুবিধা দেয়ায় এখন বিদ্যুৎ বিল শূন্য করা সম্ভব। যা আগে কেউ চিন্তাও করেনি।

(* বানিজ্যিক সংযোগে এই বিদ্যুতের রেট ১৩.৭৬ টাকা*)
তাই মার্কেট, অফিস, দোকান এর বেলায় এই সময় টা ২.৯ বছরের চেয়েও কম হওয়াটা স্বাভাবিক।

২। ব্যবসায়িক সুবিধা

যখন আপনার উৎপাদন খরচ কমে যায়, তখন আপনি প্রতিযোগীদের তুলনায় কম দামে পণ্য দিতে পারেন।
এই সাশ্রয় দীর্ঘমেয়াদে আপনার মার্জিন বাড়াবে, দাম কমাবে, এবং বাজারে অবস্থান মজবুত করবে।

৩। এক্সপোর্ট মার্কেটে সুবিধা
আন্তর্জাতিক ক্রেতারা এখন গ্রিন এনার্জি ও কার্বন-নিরপেক্ষ কারখানা খোঁজে।
সোলার সিস্টেম থাকলে আপনি সহজেই “Green Factory” হিসেবে নিজেকে প্রমাণ করতে পারবেন।
ফলে নতুন নতুন বায়ার ও অর্ডার পাওয়া আরও সহজ হবে।

৪। দীর্ঘমেয়াদে নিশ্চিন্ততা
সোলার প্যানেল ওয়ারেন্টি – ৩০ বছর
ইনভার্টার – ৫-১০ বছর সার্ভিস সহ
আমাদের পক্ষ থেকে রয়েছে সার্ভিসিং ও প্রযুক্তিগত সহায়তা

এই বিনিয়োগ শুধু পরিবেশবান্ধব নয়, বরং স্মার্ট বিজনেস ডিসিশন।
শুধু ২.৫ বছরের বিদ্যুৎ খরচ একবারে দিলে, ৩০ বছর নিশ্চিন্ত উৎপাদন –
এটাই ভবিষ্যতের গেমচেঞ্জার।
