MERX vs CatFee vs ITRX vs TronSave: Which Energy Provider is Cheapest?

TRON energy is not free, but how much you pay depends entirely on where you buy it. The difference between the cheapest and most expensive provider for the same amount of energy can be 3-4x. This article compares the major TRON energy providers - CatFee, ITRX, TronSave, TEM, Netts, and PowerSun - on pricing, duration options, and reliability, and explains how the MERX aggregator eliminates the need to check each one manually.

The TRON Energy Market in 2026

Every smart contract interaction on TRON requires energy. Sending USDT costs approximately 65,000 energy. A DEX swap can consume 200,000-500,000 energy. If you do not have energy, the TRON network burns your TRX to cover the cost - at a rate roughly 4x more expensive than renting energy from a third-party provider.

This created a market. Multiple providers now sell energy, each with different pricing models, duration tiers, and minimum order sizes. Some offer fixed-price rentals. Others run peer-to-peer marketplaces where price fluctuates with supply and demand. Some specialize in short-term rentals for individual transactions. Others target long-term contracts for businesses with sustained volume.

The problem is that no single provider is always the cheapest. Prices change throughout the day based on network demand, provider inventory, and competitive dynamics. What was cheapest an hour ago may not be cheapest now.

Provider Profiles

CatFee

CatFee offers fixed-price energy rentals with a focus on simplicity. Their primary product is 1-hour energy, which covers the vast majority of use cases - most users need energy for a single transaction, and 1 hour provides ample time to execute it.

Key characteristics:

CatFee has built a reputation for reliability in the short-term rental segment. Their 1-hour product is well-suited for users who need energy for an individual USDT transfer or contract interaction and do not want to think about duration selection.

ITRX

ITRX provides energy across four distinct duration tiers, making it one of the more flexible fixed-price providers. Their tiered model lets users choose the rental period that matches their actual usage pattern.

Duration tiers:

Key characteristics:

ITRX is a strong choice for users who know their energy needs in advance and want predictable pricing. The 30-day tier is particularly useful for businesses running continuous TRON operations.

TronSave

TronSave operates a peer-to-peer marketplace model rather than selling energy at fixed prices. Delegators list their staked TRX for rent, and buyers bid on available supply. This creates a dynamic pricing environment where costs fluctuate with market conditions.

Key characteristics:

TronSave tends to offer the best prices when network demand is low and delegator supply is high. During peak periods, however, prices can exceed those of fixed-price providers. It rewards users who can time their purchases.

TEM (Tron Energy Market)

TEM is another peer-to-peer energy marketplace that focuses on bulk orders. It caters primarily to high-volume users - exchanges, payment processors, and large dApps - that need significant energy quantities.

Key characteristics:

TEM is not the right choice for someone sending a single USDT transfer. But for a payment processor executing thousands of transactions daily, TEM's bulk pricing can deliver meaningful savings.

Netts

Netts offers fixed-price energy with a focus on short durations and aggressive pricing. They frequently rank among the cheapest providers for 1-hour energy, making them a strong option for cost-sensitive users.

Key characteristics:

Netts competes primarily on price. For users whose only priority is paying the least per unit of energy for a single transaction, Netts is often the answer - though this varies as providers adjust their rates.

PowerSun

PowerSun takes a different approach with 10 distinct duration tiers, offering the widest range of rental periods in the market. This granularity lets users match their energy rental precisely to their operational timeline.

Duration tiers:

Key characteristics:

PowerSun's 10-minute and 30-minute tiers fill a gap that most other providers do not address. If you need energy for exactly one transaction and want to minimize your rental window, these ultra-short durations can be more cost-effective than paying for a full hour.

Price Comparison

Energy prices are quoted in SUN per unit of energy per day. Lower is better. The following table reflects representative market pricing. Actual prices change continuously.

Duration Comparison: Which Provider for Which Use Case

Different usage patterns call for different providers.

Single USDT transfer (need energy for 1 transaction)

Best options: Netts (usually cheapest), CatFee (most reliable), PowerSun 10-minute tier (lowest total cost if available)

For a one-off transfer, you need energy for minutes, not hours. The 10-minute or 30-minute tiers from PowerSun can be cheaper in absolute terms than a 1-hour rental from another provider, even if the per-day rate is higher. You are paying for less time.

Batch processing (50-200 transactions over a few hours)

Best options: ITRX 1-day tier, PowerSun 3-hour or 6-hour tier

Batch operations need sustained energy over a defined window. A 1-day rental gives you comfortable headroom without overpaying for a multi-day commitment.

Continuous operations (exchange, payment processor)

Best options: PowerSun 30-day, ITRX 30-day, TronSave (if you can time purchases during low-demand periods)

Long-term rentals offer the lowest per-day rates. For continuous operations, the 30-day tier from any provider will be significantly cheaper than repeatedly buying 1-hour energy.

Unpredictable, bursty traffic

Best options: MERX aggregator with auto-routing

If your transaction volume is unpredictable - sometimes 10 transactions per hour, sometimes 1,000 - no single provider or duration tier is optimal. This is where an aggregator adds the most value.

The Aggregator Advantage

Checking one provider and assuming you got the best price is a costly mistake. Here is why.

Consider a user who needs 65,000 energy for a USDT transfer. At the time of the request:

If the user only checks CatFee, they pay 32 SUN. If they check Netts, they pay 24 SUN. That is a 33% difference for the exact same energy on the exact same network.

Now multiply this across thousands of transactions. A payment processor executing 1,000 USDT transfers per day would save significantly by consistently choosing the cheapest provider - but manually comparing six providers before every transaction is not practical.

This is the fundamental problem an aggregator solves. It checks all providers in real time, every time, and routes to the cheapest option automatically.

How MERX Solves the Comparison Problem

MERX is a resource exchange that aggregates energy (and bandwidth) from multiple providers. When you place an order through MERX, the platform:

  1. Queries all active providers simultaneously
  2. Compares prices for the requested energy amount and duration
  3. Routes the order to the provider offering the lowest price
  4. Handles the delegation and confirmation
  5. Falls back to the next cheapest provider if the primary is unavailable

The user sees a single interface and a single price - always the best available at that moment. The complexity of managing multiple provider accounts, comparing APIs, and handling failover is abstracted away.

# Using the MERX JavaScript SDK
npm install merx-sdk
import { MerxClient } from 'merx-sdk';

const merx = new MerxClient({ apiKey: 'your-api-key' });

// Get the best price across all providers
const best = await merx.getBestPrice({
  energy: 65000,
  duration: '1h'
});

console.log(best.provider);   // e.g., "netts"
console.log(best.price);      // e.g., 24 SUN
console.log(best.total_trx);  // total cost in TRX

// Place the order - MERX routes to cheapest provider
const order = await merx.createOrder({
  energy: 65000,
  duration: '1h',
  target: 'TJnVmb5rFLHPqfDMRMGwMH2iofhzN3KXLG'
});

The Python SDK provides the same functionality:

pip install merx-sdk
from merx_sdk import MerxClient

merx = MerxClient(api_key="your-api-key")

best = merx.get_best_price(energy=65000, duration="1h")
print(f"Best provider: {best['provider']} at {best['price']} SUN")

order = merx.create_order(
    energy=65000,
    duration="1h",
    target="TJnVmb5rFLHPqfDMRMGwMH2iofhzN3KXLG"
)

SDKs are available on npm and PyPI. Source code: JavaScript SDK, Python SDK.

Cost Example: 1,000 USDT Transfers

Let us calculate the cost of executing 1,000 USDT transfers using different approaches. Each transfer requires approximately 65,000 energy.

Without energy rental (burning TRX)

When you have no energy, TRON burns TRX from your balance to cover the cost. At current network parameters, a standard USDT transfer burns approximately 13.5 TRX.

Using CatFee (1-hour, fixed price at 32 SUN)

Using Netts (1-hour, fixed price at 24 SUN)

Using ITRX (30-day at 22 SUN, if you can commit)

Using MERX (auto-routing to cheapest provider)

MERX checks all providers at the time of each order and routes to the cheapest available option. Assuming MERX captures the best available price on each transaction (which varies between providers throughout the day):

Savings summary for 1,000 transfers:

MethodTotal Cost (TRX)Total Cost (USD)Savings vs Burning
No energy (burn TRX)13,500$3,240-
CatFee (32 SUN)2,580$61981%
Netts (24 SUN)2,060$49485%
ITRX 30-day (22 SUN)1,930$46386%
MERX (auto-routing)2,000$48085%

The key insight is not that MERX is always cheaper than every individual provider on every single transaction - sometimes Netts will be cheapest, sometimes ITRX will be. The value is that MERX is consistently near the bottom because it always picks the current best option, without requiring you to maintain accounts with six providers and compare prices manually.

When to Use a Single Provider vs an Aggregator

Getting Started

To start comparing prices across all providers, visit merx.exchange. The platform shows real-time pricing from all integrated providers.

For programmatic access, the MERX documentation covers API authentication, order creation, and price queries. SDKs are available for JavaScript and Python. For AI agent integration, the MERX MCP server provides 52 tools accessible through the Model Context Protocol.

The TRON energy market is competitive, and that competition benefits buyers. But capturing those benefits requires seeing the full market - not just one provider's price sheet. That is what an aggregator is for.
