5. Break-even Period

1. Calculation Results

• The graph on the left shows the payback period for a $149 Ec³ plug.

• The calculation is based on an electricity cost of $0.16 per kWh, with each ECT valued at $0.05, $0.075 and $0.1

• According to the calculations, if 1Kwh of electricity is used during peak hours every day, it will take a maximum of 100 days to break even.

2. Calculation Process

Income and Expenditure Items	$	Reference
Cost per kWh of electricity usage	0.16	https://www.eia.gov/electricity/monthly/update/
ECTs earned per green score	24	Green Score = Amount of kWh consumed * the electricity consumption coefficient for the corresponding time period Earning ECT = (Total ECT reward per mining round ÷ Sum of all users' green scores) × 90% The daily mining quantity is halved every two years, with 200,000 ECTs per day from 2024 to 2025. Assuming 4,000 non-whitelisted users, with each user consuming 1 kWh during peak hours and 1 kWh during off-peak hours, the total green score for users is 7400. At this time, ECTs earned per green score = (200,000 / 7400) × 90% ≈ 24
ECT Value	0.05	Total supply of 1 billion, market capitalization around 50 million.

• Electricity Cost: The cost per kWh of electricity is referenced from the electricity cost published by the U.S. Energy Information Administration (EIA).

• ECT Quantity Acquired: section Mining Reward in Tokenomic.
• Electricity Consumption Coefficient: Referenced from the Economic Model Overview | VI. Items to be Modified.

• Additional Note from Jianlin: 1/10 of the ECTs earned by users from mining will be used as compensation for gas fees.

• X-axis: Represents the amount of kWh electricity used by users during peak hours each day.

  Reference for the daily electricity usage range on the X-axis: The average daily electricity usage for a U.S. household (3 people) is 37.1 kWh.
