The purpose of this amendment is to change the period of performance (POP) for the solicited project and to address contractor request for information (RFI).

a. The period of performance is changed from 1

April - 30 June 2026 (90 days) to 1 April - 30

July 2026 (120 days).

b. Q11. I have the following question based on the information provided. An electric bill with two meters was included. I am assuming that one meter is for the rented property and the other meter for the observatory.

If my assumption is correct, will the

PV and battery system be designed exclusively for the observatory or will it also include the energy consumption of the rented property?

A11. The solar system should be designed to provide power exclusively for the 14 observatory buildings as stated on page 2. The fourteen buildings, excluding the 911 Building, are shown in Figure 1 of the

Statement of Objectives.

c. Q12. So far, the information provided to us indicates that the property consumes an average of 5060 kWh per month. We now have new information: the January 2026 bill shows a consumption of 2820 kWh from one meter and 1020 kWh from the other. It is necessary to: 1. Provide consumption data for the last 12 months for each meter; 2. Identify which meter is for the rented facility and which is for the observatory; and 3.

Clearly define whether the project includes the observatory plus the rented facility or is only for the observatory's consumption.

A12. 1. For the purposes of this solicitation, an average monthly electric usage of 5060 KWh should be assumed.

2. Meter number 00002534828 is believed to be for the observatory buildings.

3. The solar system should be designed to provide power exclusively for the 14
