              related to: (a) Pricing of energy, (b) sharing of renewable energy credits
              and other potential incentives, (c) capacity and delivery of energy, (d)
              incentives, penalties, and exceptions related to planned versus actual
              date of commissioning, and (e) allocation of risk related to intercon-
              nection, siting, and permitting. This activity should be started as soon
              as detailed wind assessment is complete.
              Land Lease Agreement
              Long-term land lease agreement is a legal contract between the project
              and the landowners. Often, land leases are signed not just for the prop-
              erty that contains the wind farm, but also for adjacent lands that are
              in the prevailing direction of wind. This protects the wind farm from
              other wind development that may infringe upon the wind resource.

              Community Involvement
              This ongoing activity must be performed from the outset by the project
              developer to build support for the project in the local community. An
              effective public outreach program must provide a venue to listen and
              address the concerns of neighbors. The most dominant concerns are
              likely to be environmental, viewshed, noise level, and property value.

              Project Engineering and Procurement
              Project engineering of a wind energy project includes a variety of
              tasks, some that are performed by the developer and others that are
              the domain of a contractor.

              Turbine Selection
              Evaluation of turbines for the project at hand should start soon after
              1 year of met-tower data. Most turbine manufacturers will not pro-
              vide a quote until they have examined 1 year of onsite wind data. For
              projects on a tighter schedule, turbine selection may be commenced
              with 6 months of wind data and MCP analysis, at which point the tur-
              bine class can be determined with some certainty. A contract with the
              turbine manufacturer is usually not signed until the financing entity
              is chosen and the financing entity has approved the pricing, the terms,
              and conditions for delivery, supervision, warranty, and others. In ad-
              dition, a significant down payment, in the range of 30%, is required
              at the time of contract signing with the turbine manufacturer.
                 Turbine selection allows subsequent engineering to begin. Inputs
              required for engineering are: Turbine-rated capacity, blade size, tower
              size, generator type, weight and dimensions of components, power
              curve, noise data, and variety of other inputs.

              Project Layout and Civil Engineering of Infrastructure
              Project layout is a task that begins with sizing of a wind project and
              layout of turbines using software like WindPRO or WindFarmer. This
              is a first-pass layout of turbines that meets all the known constraints:
