Rock Island Regulatory Approvals
REGULATORY APPROVALS
STATUS MILESTONES
Illinois Commerce Commission unanimously approved the Rock Island Clean Line on November 25, 2014, making Rock Island a public utility.
Iowa Utilities Board informational meetings completed in 16 counties, franchise petitions filed in November 2014.
Federal Energy Regulatory Commission authorized Rock Island to negotiate rates in 2012

Rock Island will supply 15 million MWh of clean energy per year to reduce projected REC shortfalls, helping states comply with Renewable Portfolio Standards. EPA 111(d) rules strengthen need for renewables and minimize likelihood of RPS repeal or rollback.

Levelized Cost of Energy$ / MWh
1. Based on the Lazard estimate for high-capacity factor wind, includes Production Tax Credit2. Assumes ~725 miles of transmission at $2 mm per mile, end-point converter costs of $250 mm each, mid-
point converter at $100 mm and development cost of ~$100 mm, price is flat for 25 years3. Cost of generation based on mid-point of Lazard’s Levelized Cost of Energy estimate4. Assumes $4.50/MMBtu gas price. Source: Clean Line, Lazard’s 2013 Levelized Cost of Energy Analysis

Direct Current Technology
• More efficient — Lower line losses
• Lower cost — Requires less infrastructure, results in lower costs and lower prices for delivered renewable energy
• Improved reliability — Control of power flow enhances system stability and lowers cost of integrating wind
• Smaller footprint — Uses a narrower right-of-way than equivalent Alternating Current (AC)

Economic Benefits
$7 bil l ion in new wind farm investments
$2 bil l ion investment in transmission l ine project
Millions per year in tax payments
Provides electricity to 1.4 million homes per year
5,000+ construction jobs
500+ operations jobs
Significant pollution reduction
Increased market competition benefits consumers
"Expanding transmission is ver y impor tant to the U.S. wind industr y and to Iowa. The Rock Island Clean Line enables a market for 4,000 MW of new wind, suppor ting hundreds of jobs at facilities like our wind blade factor y in Newton, Iowa."
