Energy Price Board

We scan 20 platforms every cycle — reading their SUN rates, API prices, and on-page TRX quotes. The board sorts platforms by 65k energy for 1 hour (the most popular format) and highlights the best deals. Use the energy calculator above to check different amounts and durations. Green values mean below average, blue means the absolute cheapest. Try different combinations — sometimes 15-minute bursts are cheaper than full hour rentals.

A standard USDT TRC20 transfer requires ~65,000 energy. Without renting, the TRON network burns about 14 TRX. With rented energy, you pay approximately 1–3 TRX for the same transfer — saving 80–90%. At 130k energy (for contracts or wallets without USDT), expect 2–6 TRX. The exact price fluctuates as platforms adjust their SUN rates based on demand and pool utilization.

Each platform sets its own SUN rate (the internal price unit) based on energy pool size, demand, and operating costs. Marketplaces like TronMax use bid/ask order books. Fixed-rate services like FeeSaver and NETTS have stable SUN rates that change less frequently. API-based platforms like Feee.io and iTRX offer tiered pricing with quantity discounts. This natural competition creates price spreads of 3–5× between the cheapest and most expensive option — exactly why comparison exists.

Rental durations vary by platform. The shortest is 15 minutes (TronMax, TR Energy, TronFee offer this), the longest is 30 days (iTRX). Most users rent for 1 hour — enough for a single transaction — or 1 day for automated trading. Multi-day rentals (3d, 10d) offer volume discounts: a 10-day rental typically costs 10-15x the hourly rate, not 240x. If you're running a bot doing 50+ transfers per day, 1-day or 3-day options are almost always the best value per transaction.

SUN is the internal pricing unit used by the TRON network — 1 TRX = 1,000,000 SUN. Energy platforms set their rates in SUN per energy unit. The formula is: Price in TRX = (Energy Amount × SUN Rate) / 1,000,000. So if a platform charges 36 SUN for 65,000 energy: 65,000 × 36 / 1,000,000 = 2.34 TRX. When you see prices change hour to hour, it's the SUN rate moving based on pool utilization and market conditions.

Yes — delegated energy works for any smart contract interaction on TRON: USDT TRC20 transfers, DEX trades, NFT minting, staking, governance votes, and dApp interactions. The only limitation: energy is consumed per-transaction based on contract complexity. A simple USDT transfer needs ~65,000 energy. Complex contracts like JustSwap or SunSwap may need 130,000–200,000 energy. If your transaction runs out of energy mid-execution, it fails and you lose the gas — always slightly over-estimate.

8 platforms provide REST APIs for programmatic energy rental: iTRX (HMAC-SHA256 auth), Tronex Energy (API key), MeFree (HMAC auth), Feee.io (API key), Tronify (REST with tiered pricing), APITRX (smart per-tx mode), EnergyFather, and TronMax (Setting/UI endpoint). FeeSaver and NETTS operate through Telegram bots which can be automated but aren't proper APIs. Use our feature filters on the Compare page to find exactly which platforms match your needs.

The board is updated every 15 minutes. Each platform is scraped sequentially with a short pause to avoid rate limiting. The pipeline: scrape → aggregate → fill gaps (cross-platform price estimation) → publish. Prices marked with “≈” are estimated from market ratios rather than quoted directly by the platform, and platforms whose last successful scrape is older than 3 hours are flagged as stale and excluded from rankings. The generated_at timestamp is shown in the header badge and footer so you know exactly how fresh the data is.

Energy delegation in TRON is non-custodial — the platform delegates energy to your wallet, and you pay TRX. The energy is assigned to your account on-chain; the platform cannot take it back during the rental period. Your funds never leave your wallet except the TRX payment. If a platform disappears mid-rental, your already-paid energy remains delegated until it expires. No staking, no lockup, no smart contract approval needed. Always verify reputation and start with small amounts.
