Programmatic R&D Needs<br />
The above areas for innovation can only be attained if strong RD&D programs are in place that nurture<br />
this early industry. Although there are no programmatic silver bullets, these guiding principles should be<br />
pursued to ensure success:<br />
ÌÌ<br />
Clear focus on cost-reduction pathways -- Continued benchmarking of technology innovations with<br />
respect to their contributions to reducing the CoE is an important factor in identifying solid cost-reduction<br />
pathways and measuring program success. It is important that such benchmarking occurs by modeling<br />
commercial-scale arrays from a performance, cost, and economic point of view. Cost drivers at commercial<br />
scale are different from the cost drivers at pilot scale, and it is important to engage in the design and<br />
optimization process with the end goal in mind.<br />
ÌÌ<br />
Demonstration and validation -- Demonstration projects allow the design community to develop a<br />
comprehensive understanding of all the elements contributing to the CoE of a particular technology. It is<br />
important to transfer the knowledge gained from these demonstrations to the development community<br />
so novel design concepts can incorporate those lessons without having to repeat their mistakes. An<br />
independent test and validation program can go a long way toward achieving that goal. While this has<br />
proven to be difficult to implement, given the commercially sensitive nature of this type of activity, it is a<br />
critical ingredient to accelerating technology innovation. Such independent validation work can then be<br />
fed back as lessons learned into computational codes and design standards.<br />
ÌÌ<br />
Development of strong theoretical modeling capabilities -- The key difference between engineering<br />
capabilities existing 30 years ago and today is that modern computing capabilities allow rapid simulation<br />
and trade-off studies to be performed on devices that would have required extensive physical testing<br />
in the past. Moore’s law, which predicted that computational capabilities double every 18 months, has<br />
largely held true over the last 30 years (back to when wind power was in its infancy). Over this 30-year<br />
period, this yields a millionfold improvement in computational capabilities. By far the most fundamental<br />
technological difference today, theoretical modeling allows innovation cycles to be accelerated, enabling<br />
