I don't live in your state, but will try to help you. Much of the below information was from a ChargePoint conference. You may want to reformat the most important points into a letter.
1. As more EVs are purchased, more charging infrastructure is needed.
2. EVs can be charged at home, eliminating the time and cost of trips to gas stations.
3. There are wireless charging options such as Plugless Power that make charging an EV virtually effortless.
4. People can now get an EV as their only car and travel across the country by relying on fast charging infrastructure.
5. Automakers are also embracing EVs, which are better cars because they are more reliable and have fewer parts to break down (e.g. no spark plugs, complex transmissions or fuel lines that are associated with gasoline engines).
6. There are more than 25 EVs available on the market today.
7. EVs offer environmental benefits since they do not have emissions.
8. Certifications are available for new and existing buildings. US Green Building Council LEED certification is one possibility.
9. Level 1 charging uses 120 V and can add approximately 40 miles of EV range overnight (4 miles per hour additional).
10. Level 2 charging runs at 240 V and the additional range can be from 10 – 60 miles per hour.
11. Level 3 charging generally uses 480 V, and requires a 3-phase power supply. This method currently offers 100 - 300 miles of additional range per hour.
12. Organizations may be able to get credits for installing EV charging stations. Certain conditions might apply, such as having a minimum 2% of spaces set up for EV charging with Level 2 or above.
13. There may be other incentives available for installing Level 2 chargers.
14. Case study:
a. A commercial manager in Atlanta was looking to attract new business tenants.
b. The buildings were constructed prior to most EVs being available.
c. A Department of Energy $1,000 grant was offered for the installation, paying for the cost of the ChargePoint stations.
d. Initially, four Level 2 chargers were installed at the first property and another four stations were added at another property.
e. Since the stations were installed, several tenants decided to purchase EVs since charging them would be significantly easier with the new stations in place.
f. A minimum of 35 EVs are now in these Atlanta commercial properties, all supported by Level 2 ChargePoint stations.
g. As a result of the program, tenant customer satisfaction is high.
h. They continue to add to the EV charging infrastructure today.
