Who is eligible?

Must be a current institutional or public/private entity that receives electric service from Entergy Arkansas. This includes, but is not limited to, K-12 schools, accredited higher education institutions and local, state and federal governments and municipalities.

What are eligible upgrades?

Below is a list of upgrades and repairs that are eligible for CitySmart incentives:

• Improved building design (new construction only).
• Interior/exterior lighting retrofits.
• Interior lighting controls.
• HVAC controls and upgrades.
• VFD motor drives.
• Commercial refrigeration.
• Commercial kitchen upgrades.
• Direct install (low-flow faucet aerators, pre-rinse spray valves, shower heads, LED bulbs, weather stripping, overhead door infiltration).
• Waste water treatment plant fan/blower/pump retrofits.
• CoolSaver air conditioner tune-up.
• Advanced Wi-Fi thermostats.
• Behavioral Savings (Continuous Energy Improvement).
• Retro-commissioning Lite (RCx Lite).

Typical Elementary School Project

This example illustrates a possible scenario that might exist at an elementary school. Simulated existing conditions and sample proposed retrofits are listed with example calculations of energy savings, incentives and simple payback. The data given below is not necessarily indicative of what you may see at your site, but can be reviewed to understand how the program will operate and the potential value of the CitySmart Program.

Existing Interior	Retrofit Interior	Annual Energy Savings (kWh)	Assumed Blended Electrical Rate ($/kWh)	Annual Energy Savings ($)	Entergy Base Incentive Rate	Entergy Bonus Incentive Rate	Total Incentive Amount ($)	Est. Project Cost ($)	Est. Simple Payback (Yrs)
(200) 2’x4′, 4 lamp T8 with electronic ballasts W/O Occupancy Sensors	(200) 2’x4′, 2-lamp LED fixture  WITH Occupancy Sensors	47,108	$0.080	$3,768	$0.12	$0.00	$5,653	$14,000	2.2
(100) 2’x4′, 3 lamp T8 with electronic ballasts W/O Occupancy Sensors	(100) 2’x4′, 3-lamp LED fixture  WITH Occupancy Sensors	15,642	$0.080	$1,251	$0.12	$0.00	$1,877	$7,000	4.1
(50) 60 watt incandescent bulbs	(50) 9 watt LED bulbs	7,600	$0.080	$608	$0.12	$0.00	$912	$950	0.1
	TOTALS	70,350		$5,627			$8,442	$21,950	2.4

The total annual savings would be approximately 70,350 kWh, resulting in an estimated $5,627 in annual utility savings. The estimated cost of this project (using the above simulation) is $21,950, with an estimated incentive of $8,442. If the facility were to make these upgrades, the net project cost to the customer (after incentive) would be $13,508, yielding an approximate 2.4-year payback period.

Typical Wastewater Project

This example illustrates a possible scenario that might exist at a reasonably large wastewater facility. Simulated existing conditions and sample proposed retrofits are listed with example calculations of energy savings, incentives and simple payback. The data given below is not necessarily indicative of what you may see at your site but can be reviewed to understand how the program will operate and the potential value of the CitySmart Program.

Existing Conditions	Proposed Retrofits	Annual Energy Savings (kWh)	Assumed Blended Electrical Rate ($/kWh)	Annual Energy Savings ($)	Entergy Base Incentive Rate	Entergy Bonus Incentive Rate	Total Incentive Amount ($)	Est. Project Cost ($)	Est. Simple Payback (Yrs)
(1) 300 HP Aeration blower with throttling controls	Provide (1) new 250 HP high efficiency aeration blower with VFD controls	735,929	$0.065	$47,835	$0.10	$0.04	$103,030	$475,834	7.8
Existing “coarse bubble” diffuser system	Replace existing with a “fine bubble” diffuser system	169,080	$0.065	$10,990	$0.10	$0.04	$23,671	$43,000	1.8
(25) 250 watt metal halide fixtures around the facility	(25) 4-lamp T8 fixtures to replace the metal halide fixtures and add occupancy controls	10,665	$0.065	$693	$0.10	$0.04	$1,493	$2,704	1.7
(40) 2’x4′, 4 lamp T8 with electronic ballasts with no occupancy controls	(40) 2’x4′, 2 lamp T8 fixtures with premium efficiency ballasts and add occupancy controls in some areas	8,011	$0.065	$521	$0.10	$0.04	$1,122	$3,090	3.8
	TOTALS	923,685		$60,040			$129,316	$524,628	6.58

The total annual savings would be approximately 923,685 kWh, resulting in an estimated $60,040 in annual utility savings. The estimated cost of this project (using the above simulation) is $524,628, with an estimated incentive of $129,316. If the facility were to make these upgrades, the net project cost to the customer (after incentive) would be $395,312, yielding an approximate 6.6-year payback period.
